The Sinn 903 is not technically a homage. When Breitling went into administration in the '70s, Sinn went in and bought the rights to the Navitimer, making them one of only three companies allowed to make slide rule bezel chronographs in the 'Navitimer' format (the other two being O&W and, of course, Breitling). Sinn gave it the 903 model designation, but (after a few legal battles with the revived Breitling) were not allowed to use the Navitimer name. Sinn actually developed the navigation chronograph, improving it, hence it has improved water resistance over the Breitling equivalent.

I'm Sinn fanboy. Own 556ib, 356 flieger, 104 in blue, and the 144. When I first got into watches, Sinn seemed like the perfect company for my lifestyle and represented a tremendous value for their products. They use top level movements in all of their watches and they are regulated. A Sinn rep also told me via email after servicing my 356 that they regulate all of their movements slightly on the faster end of COSC. This is because they say that the movements tend to slow down and lose time over the years between services. This has been true in my experience. All of my Sinn pieces run around +4 to +6. They are finished very well and the company actually does have great customer service when it's time to get your watch serviced. If you're just getting into watches or a seasoned collector the 556 or the 104 are great introductory pieces for the brand. But I think getting a watch with all the cool technologies that they offer is the coolest part of the brand. Dehumidification capsules in the case, oil filled cases, Diapal escapements, low pressure resistance in case you need to eject out of a fighter jet 🤪, UTC complications for traveling, tegemented cases and bracelets, tide timers, magnetic field protections, and extreme temperature resistances for operating in extremely cold or hot environments. I mean no other company is doing things like that to the level Sinn is. They bought the rights to the navitimer from breitling and make it better than them in my opinion. The Sinn 140/142 has also been worm on I think at least 2 but maybe 3 space missions also. Sinn has made watches for Bell and Ross and have also worked with Damasko. The brand is pretty cool and they are durable affordable. The only thing I can knock the brand for is they use anti reflective coating on the top side of the crystal. I'm not fond of this but I'm pretty positive my Omega seamaster 300 has AR coating on the top side of the crystal also. The coating can be scratched and makes it look as if the crystal has scratches on it over time. And I also don't like Sinn divers a whole lot but that's just personal preference. I just don't like the hands and the dial layout. I'm sure they are made extremely well.

One of the brands you "stumble" on and wonder why have I not seen these before! The catalogue is immense, and they do what it says on the box, no pretensions, no overkill...just great pieces and moreover the majority are tool pieces designed for a specific niche, but appealling to people who enjoy that! And fantastic value is the icing on the cake, just great everyday wearers!

Cannot say enough good things about Sinn. I own a 556a and love everything about it. The 104 with arabic numerals is the textbook definition of a one-watch-collection candidate. 🙏🏻

The 556i was my gateway watch. Great value. Super clean and uncluttered. Excellent quality. The epitome of a German watch, as far as I'm concerned.

Sinn is on my list of grail brands to own. They’re just so aesthetically perfect. You get more than what you pay for.

Sinn finally get some long overdue love. Great video - very informative. Lots of Sinn models not included, which just shows how much they have to offer. Every collection should have a Sinn.

Finally a full and respectful rundown on the truly greatest tool watch brand there is. Top stuff.

You put it so succinctly, “Some of the best value for money German watches out there.” I have always loved the U1 but, like yourself have never been aware of how many models they actually have available. Some amazingly well designed pieces on show here. They really are truly great utilitarian tool watches. Yet another top notch video from you here my friend. Always educating and entertaining! ✊

I love how this is just you going through their repertoire, not even taking a look at the history of the brand in particular or taking pros and cons, just taking a look at each watch one by one and mentioning what details you see and what you like about it. Not mentioning prices or quality or the movement, just talking about the design. This somehow spreads positive vibes and makes me want fall in love and buy every one of these watches. Really love watching ypur contet. Keep up the good work

I have a Sinn 104. Absolutely love it. It's a keeper!

Sinn is a fascinating brand and deserves more praise and recognition than it gets.

Wow, talk about falling down a rabbit hole, that 15 minutes just flew by

Underrated brand that doesn’t get the love it deserves.

Excellent video! Thanks for putting this together 👍 3 years ago I attended a WatchBuys’s Roadshow and was blown away by the quality, innovation, technology and design of Sinn’s watches. I’m now the proud owner of a few Sinn’s. So far I’ve acquired a EZM9, T1, T1B, U1 Professional and a 836. Their Tegimented steels, U boat, stainless steel or titanium, are just amazing in their ability to resist scratching. Using Top Grade movements is a big plus too. All of my Sinn’s run within COSC specs. Needless to say, I’m a huge Sinn fan 🍻

Notice how beautiful these matte bezels are. Much better than the shiny ceramic bezels we see nowadays. Thanks for wonderful overview ⌚

It’s 2023 and I finally got into auto/mechanical watches. I own a sinn 13.1 and totally love it. So legible so masculine and so sexy imo! The kings of understanding legibility, line weights, and emphasis on their individual purpose..

Love this video. Thank you for giving such extensive coverage to the whole line. You accomplished your goal to inform us that there's more to this brand.

The Sinn 356 was my first automatic watch! Seeing the 356 mentioned on your video made me smile. Your channel has helped me learn how to articulate my own taste in watches, thank you!

I have a regular U1 and a U1S. Worn them all around the world in 20 countries. It tough as nails, understated enough that it doesn’t attract attention, but always gets attention from watch lovers. I own several more expensive watches but the U1 seems to always get the most wrist time. Just an outstanding time piece.

I liked them all. Beautiful, Elegant, and Functional Timepieces obviously well engineered!

At this point in collecting I have sold almost 300 watches and narrowed by collection to only Sinn. Gone over the last two years are all: Rolex, Omega, Tudor, GS. Bought my first Sinn, a 556A-RS in 2020. Now have four and will buy 1-3/year. Absolutely my favorite brand I have ever owned.

I definitely want to add a Sinn into my watchbox in the not-too-distant future. It's a watch that I can actually read the damn time with.

Love These watches! Simple, High Contrast, Elegant! Beautiful Timepieces! I Love the Chronographs!

Outstanding. Great presentation and great brand. Becoming my favorite watch channel.

They always remind me of the Porsche 911. Engineered so precisely with no need for flashiness. Just gets the job done. Love this brand.

A great review of Sinn. I love the execution and sheer simplicity of the 556i....I have just got to get one.

I really enjoyed this. You make some very interesting observations.

I got the 104ABE recently and love it, there’s something so nice about a proper smart tool watch. That you don’t have to worry about but yet looks good when you need to be smart. It’s a strap monster and from a leather strap to an orange NATO it completely changes whilst still looking great.

Another great video IDGuy. Sinn has definitely been a brand that has been on my radar. Well built and utilitarian tool watches at their best.

The 856 is one of my favorite watches in my collection. Which contains Rolex, Omega, JLC, etc. Simply spectacular watches

Thank you IDGuy, that was a great run through of the Sinn watches that have been off of my radar.

Love Sinn. I've owned ten over the years and loved them all in their own special ways. Selling my EZM3 is probably one of my biggest watch-selling mistakes.

I don't own a Sinn but have always been attracted to them, I'd love to own one in the future, they have the ultimate utilitarian aesthetic and from everything I've read they can back it up, really cool brand, I think my first German watch would be a Sinn.

I have two Sinn watches that complement each other ; 104 St Sa A (Arabic numerals) and U1 B and both are fantastic and your presentation was excellent summing it all up extremely well. Tremendous respect for this brand as they deserve kudos. I love your Saturday night live and you are a great host with the difficult task of reading Chat as well as presenting. You are very intelligent ID Guy

The Sinn Navitimer (Sinn 903) has an interesting history. After the quarz crisis bankruptcy of Breitling, Sinn bought the rights of the Navitimer as well as the leftover cases and dials and kept producing them because the watch was widely popular amongst pilots. Sinn focused on further improving the Navitimer. Meanwhile A Company called Sicura owned the Breitling Name aswell as the Navitimer Name, later resurecting the Brand and the watch. Sinn still has the rights to the 806 Navitimer and all the later iterations that they made, which is why they still have that watch in their portfolio.

Yeah, you now know why I love it. Sinn watches are definitely the watch most watch enthusiasts should try. Their taste can develop from these watches even if they don't like it. Btw, Sinn 903's design is better than Breitling's Navitimer because it has a much cleaner look IMO.

Fabulous review! always love your videos and a Sinn fan this one was amazing!

Great video showing the (maybe mostly unknown) variety of Sinn watches. I'm very much looking forward to collecting my first Sinn watch (104 with the white dial) next week.

The 903 IS the REAL Navitimer ... Sinn bought the equipment and the rights to the watch. The 903 is more of a Navitimer than the current Breitling Navitimer.

Great video about a great brand. Love my 556i and 103 Ti Diapal.

I've owned four Sinn watches (556A, 856, EZM 2, currently EZM 13) and I love the brand. When people ask me about it (which are only ever watch nerds) I tell them I think Sinn is what Rolex was in the 60's. A real tool watch with state of the art tech. The only issue I have is the inability to see them in-person in the US. I wish they had some sort of dealer network as I really don't like buying watches without trying them on.

Absolutely top quality watch brand with very little amount of advertising. Next stop, Damasko!

Great review and an introduction to the entire line. Really liking Sinn.

Great Video, Thank so much for all your hard work putting this one together. I am more of a high end watch collector, but these Sinn watches are doing it for me. Wish there was some dealer in NYC area to try them on, i'd like to pick up a few. keep up the great work!

just bought myself the 556i before the price goes up again on these, just the best value for money tool watch with decent bracelet going around.

Great video on Sinn watches. I own a 903 in blue on blue leather strap, and a EZM13 on steel bracelet. Superb quality and attention to detail from Sinn.

what a great video. Thank you, I knew Sinn only because of the popular models... god, what I was missing

Excellent Sinn overview video. Love my 856 UTC!

Great info. This was so helpful. Thanks!

Hey IDGuy, You did an excellent job in this segment and I feel compelled to mention two additional Sinn follow up points. Firstly, I think that you neglected to mention Sinn’s involvement with the storied Heuer Bundeswehr Chronograph program and this remains the stuff of military watch legend. Next, for those brand enthusiasts that find themselves in Frankfurt am Main, a visit to the Sinn factory is not be missed. What the brand may lack in the way of a bricks and mortar dealer network in some locales, it makes up for in spades in hospitality.

that was a brilliant review of the sinn loved it

Great video. I have the white dial Sinn 104 but very keen on the new U50! Thanks.

Thank you for the vid. I am still not convinced, but my curiosity is sufficiently piqued to try some out on the wrist next time I get a chance :)

I'm watching this wearing a Sinn EZM3F. Best piece I've ever owned.

love the style and love the utilitarian aspect - my fave brand

I am glad everyone has a favorite brand of Watches. I see the same features in every watch shown here. Not my cup of tea. I think it really is for working people who dive fly drive and saves lives. This is the brand these people need. Enjoy your collectibles , Don't sell them Pass them down Good video for Sinn

Sinn is definitely a strong favourite of mine as well as Damasko, great video!

AFAIK the 903 isn't actually a hommage, I'm pretty sure they have the rights to the design.

I have the Sinn EZM 1.1 and the 103 - The blue one at 4:08 in this video. I love their watches. Technically advanced, hardened tegimented steel and great lume. Also great water resistance. I find their service isn't bad either. Great watches and a great company. I'm looking at a U1 or the new U50. Also don't forget their more formal watches, including their Sinn 910 rattrapante or split seconds chronograph and their damascus finished watch. I dream about their EZM 15 which is another central seconds chronograph.

Loved the video, SUBSCRIBED!

Great vid, now I blame you for getting me into Sinn 😂

Excellent brand summary..great work..

Great review of this brand. Worth noting that while most know Sinn for their utility watches, they also do fine dress/formal watches and a great line of women's watches (a generally weak area for many brands). One of the few brands that make true modern tool watches. Most watches labelled 'tool' are really dress/tool or casual/tool. My only criticism of Sinn is that they tend to function over form, but in their best watches the supreme functionality creates a handsome aesthetic.

Awesome lineup, they’re perfect, some day!!!

The Sinn 203 with full black bezel is absolutely stunning yet so tool like in styling all in one

Sinn 144 St Sa ....the best ever Sinn..one of the best looking chronographs, period!

It’s really great brand👍 I have Sinn ux more than 5 yers, it’s amazing watch with oil, no scratch at all, I just want more Sinn. I’m thinking about 556 A RS and 857. Thank you for a good review about Sinn👍

Super presentation, thanks.

Many thanks for your Video - Sinn is such a Great Brand!

Wow what a video👏🏿👏🏿. Sinn one of my favourite brands 🔥🔥

Own the 104 ST SA A. Lovin’ it. Plan to own more too 😇

Just received the Sinn 856.7661. The tagimented matt finish looks so good in person.

I’ve been through a few 556 and 104 models looking for that perfect under the radar tough daily wearer. Finally ended up with an EZM-3 and it just feels natural, and hardly anyone wears it. Eyeing the 856i as well...

The 756 is such an underrated watch. Without a running seconds hand, you have possibly the cleanest, most legible chronograph out there.

I love the Sinn Flieger and the 903 Navitimer pieces.

Welcome to the Sinn fan club IDG!

I love all the pieces!

Love the 556 great value.... I have the 104 white dial and it’s great with nato

Wow, great video. Thanks.

I currently own the 556I, Damanzener ( very very limited production ) and just arrived is the U50 MOP. Great brand in terms of quality , austere dials and tech

Great video, thanks, any thoughts on the Frankfurt, financial district watches ? they look great, and also the classic ones.

Nice presentation!

Thanx - very well made video!

There are also a lot of very interesting and useful technical complication unique to the Sinn-brand, like Tegiment (steelhardening), Ar-gass filling with moist-absorbing capsule in the watchcase, Oil-filled Hydro-cases for under water legibility at every posssible angle.

Great vid 👍 *SINN FOR THE WINN! Everything you need in a watch, and nothing you don't.* Typed with a 104i St Sa A (grey/H-link) on wrist - edit: I guess I'm a member of the 104 cult 🤷🏼, and with plans on a 556i RS to keep it company soon. I could dump the rest of the collection and still be perfectly happy going forward with only 2 Sinns. Well, ok, keep the G-shock solar/atomic squares, the GW5000U-1JF and the 5610U with the Ti mod. Ok, and maybe add a white 104i or 105. And *definitely* an EZM. The "U" series is 🔥. And keep a couple mod builds. But srsly, could focus my collecting niche on GER tool watches and be very satisfied. 5:45 - that grey 900! 🤤🤯🔥

Thanks for covering Sinn. These are the toughest watches made... I want the 356 with acrylic crystal. Great chromo for 2k.... you should cover the special features of these...tagmented steel, copper sulfate crystals, anti magnetic and inert gases used...

You nailed it. Great watches The Porsche of timepieces.

Another excellent analysis!You have Sinned, therefore you are possessed 😁

Love my Sinn 103 sa B E and Sinn 856 S UTC - bought those VAT free plus a healthy discount a couple of years ago. Both get a lot of wears despite also having the Speedy Sapphire Sandwich, IWC Pilots chrono and Tudor Pelagos LHD in my collection.

Great review of the brand. Next time of the watch shots please include the model numbers. Own a Sinn 856 b uhr feilger on bracelet. Great daily tuff as ever. Have order a U50 T on bracelet a model of a smaller version of the U1. Sinn listened to customers wanting a smaller U 1. And came out with one. What brand does that? Thanks for your shows and content. Stay healthy safe and warm.

I just purchased my first Sinn (EZM 1.1). It’s built like a bank vault. Actually, if bank vaults were built like Sinn, there would be fewer bank robberies

I've flipped 3 Subs in my collection. My recently purchased 104 ABE fills the Sub hole to where I doubt I'll ever feel the need to buy another Sub.

Sinn is terrific. I have the 104 LE with tan lume and the contrast is still fantastic. In part it’s the little things, like the white outline on the hands that make them pop, despite the softer tan. But they don’t quite seem to know how to take their identity and translate to a dress watch. The latest ones are hard to embrace.

My favorite Sinn line is actually the Frankfurt Am Main series! Dope watches.

Fantastic video

I have a Sinn type 144 Ti GMT for some 23 years now. Ti stands for titanium housing, that is (unfortunately!) not offered anymore, while GMT stands for the Valjoux 7752 with an additional hand, showing a 2nd time zone. It's the professional watch that I use for travelling overseas since I've got it, and I use it, too, when going to the work shop where there is dirt, steam and somtimes the need to put hands on something. With the last service, I ordered to add a DIAPAL escapement working lubrication free and opted for the Ar-dehumifying technology, containing much tighter EDR seals, argon filling (inert gas) and a drying capsule to prevent / delay aging of the lubricant. Now, 5 years after the last service and occasionally working in an environment with a lot of steam, the watch still has an accuacy of + 1 ... 5 s/day, while in former times it had to get a service after that time. While other watchmakers write things like "Engineer" on their dial, this whatch is a true and sturdy engineer's companion. @ ID Guy: To my understanding, it's these particular features like Diapal escapement, Ar dehumifying technology and so on that made Sinn become a quite outstanding chronograph supplier, not just because of that very clear high contrast design. One more thing: I choose the 144 type because this was one of the rare examples with a tachymeter on it's dial, enabelig me to read the speed per hour from a time measurement (that's why I have a chronograph / stop- watch complication). I'm working in plant engineering, so I can easily check production volumes per hour or when driving a car, check true speed (rather than believing the inaccuracy of the speedometer). I really dislike the pulse scale (that covers all speeds above 190 units / hr) of my 144 type watch (not because of speeding) on one side and on the other side I just can't understand, why buyers of chronograph watches accept when there is not tachymeter scale there - what do they need that type of watch for if not for time measurement?

Loved this. I would love a video on no date watches, the symmetry is beautiful and would like to know your thoughts.

Choosing the reference 5.56 for a field watch definitely makes sense.
