Thanks for creating these educational videos. For me, knowledge is an important part of being a watch enthusiast.

Man, the GMT has to be one of my favourite and more useful complications!

This was by far the best explanation of how GMTs and the different movements work! I just purchased the Seiko 5 SSK003 "Batman" GMT and love it!

Great video and content as always Teddy. You just answered a lot of questions I had about GMTs.

I’m glad I’m not the only weirdo that appreciates all these tiny details about watches, I’m not gonna lie the Tudor Pepsi was looking like the choice but the ball Pepsi with the blue dial is special. Nice one my guy 💪🏾

Your explanations are always the best. Great video, as usual.

I really missed these strictly instructive videos from teddy... Amazing watch-commentary pair up and on point as always! Thank you so much 🫶

Love these educational videos. Thanks, Teddy…!

Absolutely fantastic video Teddy. Great explanation, there were some complications I had no clue about before your explanation. It seems the new Seiko GMT movement is an "Office" GMT but despite more work to set it up I'm sure it's fine for traveling. I do admit though I tend to throw on my G-Shock Mudmaster GG-1000 Ana-Digi or for a smaller fit my Casio Royale AE-1200 where home time and destination time are right in front of me without thinking about it! $30 and every time zone, that's even indicated on the little digital map! 😁

Best GMT video out there to explain all of the various types. Thank you Teddy!

I love my Tudor BB GMT since I bought it one year and five months ago. I love it. Thanks for another excellent video Teddy.

Your timing is great. I just got the new Seiko 5 SSK001 GMT. I was also confused about caller/office vs. true/traveler. Thanks for the informative video as always. Absolutely love your content, Teddy. Let me know when you're in LA and I'll buy you a fat burrito.

Exactly what I needed to learn! Thank you again, Teddy!

terrific overview Teddy

Great video. For those on a tight budget, I recommend the Casio Royale (AE-1200) - a world time watch for under $30.

Thanks for the explanation of the True vs caller GMT. Never really understood it.

Great video, very comprehensive as usual! For the last “budget” option I was thinking about the rado captain cook over-pole as well with its world time bezel.

What a awesome video that cover pretty much all there's to learn about GMT watch; great work Teddy, keep the good efforts !

GREAT explanation. Finally cleared things up for me. Thanks Teddy! 🙌🏾 ⚡️

Thanks very much for explaining the GMT and other the other types as well!!!! You are very much appreciated!!!!

I heard you talking about GMT watches in other videos and had no idea what it meant. Thanks so much for this.

Great Video! Thank you. Also thanks for showing the difference in setting a caller vs. traveler GMT.

Great video Teddy, really enjoyed this one and am in the market for a GMT...HELPFUL!

More one perfect vídeo. Congratulations from Brazil!

Great video!

Teddy my favourite ringmaster

Excellent video with clear explanations.

Liked this one - thanks. I know you mainly focus on autos, but Citizen and GShock worldtimers do some neat things with multiple time zones - especially the ana/digi models. I've got this GShock Gulfmaster (which is a beast but I love it) - you set up your times (one for the analog handset, one for the lcd) and when you travel and want to swap you just press a button and the hands move by themselves. Which is very cool if you're a big child like me. Take care.

Just when I was starting to realise I don't know how to set some of the GMT complications but too embarrassed to admit it here comes Teddy to the rescue. Thank you sir 👍

Really helped with understanding what a GMT-watch is, didn't think I would need one but now my collection feel the lack of it.

Great video. One 2nd time zone feature can be found in chronographs with the chrono minute and hour counters co-axially mounted together. But the chrono must come with a 60 minute counter.

All the vids are great. Thanks for all this content

Great video as usual!!!

Bravo, another amazing video... THANK YOU

I recently got the Oris Aquis GMT Date, 24hour time scale on the face AND a rotating bezel. Simultaneously tracks 3 timezones. 👍

Very informative. Thank you.

Ya, definitely helped. I learnt a lot. Thanks!

Great video, thank you! Good explanation

My favorite world time watch is the Seiko Prospex Solar SSG015 - World Time Radio-Sync Solar Chronograph. No need to manually set the time because of the radio sync. It’s a bit clunky because of all the complications but is by far the coolest piece in my collection and definitely a conversation piece.

Amazing video. The GMT is my favorite complication. I have a GMT Master II Pepsi and a Mido Ocean Star GMT. The Mido also has a true GMT movement.

I'd also consider the JLC Reverso Duoface as a GMT as you can have each face showing a different time zone and the travel time has a jumping hour mechanism

Love the piano Teddy, a great touch☺️

Great video!👍

Really appreciate this education

GMT is my favorite complication. Great video!

Packed with information. I like this type of video

Listen. I learn from Teddy Baldassarre. This content is so great, I watched it twice.

Simply spoken, well addressed.

Terrific video Teddy! There is another permutation on the WT watch in the Montblanc Geosphere. A beautiful way to represent time.

Very helpful. Thank you

Teddy, this is the best video I’ve yet seen discussing GMT watch types and functionality. Nice work. 😎🌎🌍🌏⌚️

i love the last one (12hr rotating bezel) because i can confirm the future relationship of local and home time zone. it helps me to decide when to set meeting in the future.

Excellent video! Zodiac has nailed the summer watch look, that's for sure.

Great video. I love GMTs. Some hobbyists are dive watch guys; others are dress watch guys. I am and will forever be a GMT guy.

Once again teddy thank you for the history lesson I make sure I all ways like your vids very knowledgeable

Thank you this was useful.

Very nicely done.

Fantastic video.

There are some really cool GMT watches out there, but personally I don´t travel that much and I don't have the need to track an second time zone so these are the type of watches that I wouldn't buy, but I enjoy so much to see them

I dodn’t know quite a few things mentioned, but the most surprising is that you’re usually unable to quickset date on true GMTs. Had no idea and honestly I think I prefer the simpler movement. I swap watches too often and I’ve got to set my date all the time, true gamechanger

Hi Teddy! Finally, an explanation of the GMT watch variations that makes sense, and so much detail packed into a short video, very much appreciated. I bought a Tissot Chemin des Tourelles Powermatic 80 GMT-24h watch a few years ago and until now, I never knew whether it was classed as a 'real' GMT watch or not. It has a 24hr scale on the dial face on the outer edge for one time zone, and once the hands have all been set, the smaller hour hand can be rotated independently back or forward without interrupting the other hands. I gather from the video, this makes it a true GMT, correct? I liked the fact that it was an automatic as apart from 3 Quartz watches I have in my small collection, the rest are either automatic or manual, oh and one solar powered quartz which I like because the battery is unlikely to need replacing in what's left of my lifetime, the other Quartz watches are a pain getting batteries replaced (TAG Heuer, Rado and LV). Cheers!

I have an Ulysse Nardin Dual Time base on UN-334 in-house caliber with pushers, which is also a very interesting and convenient way of having two time zones. New Grand Seiko GMT is quite cool too

Professor Baldassarre, Dean of the Faculty of Horology, thanks very much from this new student. Cheers!

Just got a Mido Multifort GMT Wordltimer, I love it!!

I love my Citizen Satellite Wave with F150 movement. When getting off the plane, I just tell it to listen for the GPS signal and it knows exactly where I am. It does NOT track my home time, but super easy to reset to the new local time, extremely precisely. I also have a Russian Vostok with a 24 hour hand and a rotating bezel that is pretty handy. You can't independently reset the fourth hand, nor the hour hand, but graphically it is very simple. It's so simple it doesn't even have a date quick set. Another one I have that is handy for travelling is another Citizen and a very common one at that, the Nighthawk. And a little surprise for quickly resetting the hour is my Timex (don't know the precise model). It is one they made recently with wire lugs and looks a lot like WWI trench watches. It came on a very soft "bund" strap made in the USA. Cool little watch that can quickly change the hour hand only. Lots of fun options out there!

I am so into that Zodiac - the white and green pops so nicely

That was awesome

Excellent video

Helpful thanks

The first time I was on a connecting flight through SLC I realized what a pain it is to have a caller GMT. Next I did my researched and figure out the whole caller/traveler thing. My next watch was a Glycine Airman Purist which actually has a caller GMT movement (2893-2) but it has no 12 hour hand, it is a 24 hour watch which I grew to love. Now I have a Panerai 233 which is a traveller with a 12 hour "GMT" hand but a matching 24hr sub dial for AM/PM. This allows me to cover up the GMT hand w/ the hour hand when I want to clean up an already tidy face. It is a fun discussion on what could be called a "TRUE" GMT. If you're sitting at home it's no big deal to spin a traveller GMT around to suit your needs but when you have I tight connection and all you have to do is pop the crown and rotate the local 12 hour hand up or back an hour or two it truly makes sense.

Most excellent!

I have a few GMT watches and like them all. Some are easier to set the GMT hand than others. My favorite is the Seiko Landmaster Spring Drive. That watch for the money has a great but underrated movement.

Really appreciate all of the effort you put in these videos! However I think you should at least mention the seiko or citizen options that have multiple timezones and GPS sync to keep them updated automatically

I had a need for an office GMT. In a pinch, what I did, was to use the bezel on my Seiko Skx007. I needed to track Phoenix time and Madrid time. I just positioned the 12:00 mark at the 3:00 position and read the time that way. It works! 😅

Thanks Teddy! I love & learn more about my Luminox Commando... Great Vidya 😁😁😁 GMT is cooler the same I thought 👍🏼

Very well made video! Now I want a GMT watch just for the cool factor. Had never understand the aftermarket half colored bezel with 12h scale. Now I know they just don'r know what they are doing. haha Subscribed!

In love with my black and white Planet Ocean gmt

Thanks Teddy!! Any chance you can do a video on d.dornblüth & sohn?

Seiko SUN023. true GMT kinetic tuna. Thanks for another great vid

My favorite GMT right now is the Grand Seiko Evolution 9 GMT, reference SBGE285 - a stunning titanium watch with spring drive to boot. I'd love to see a review.

You should do this kind of video for all different watch types! I'd love a video on the history of dive watches

Just found out my Tudor “root beer” should be arrive at my AD soon! Really excited about that one.

3:09 I think people massively understate how much of an influence Pan Am had on modern aviation as we know it. Fun fact, not only did they popularise the use of GMT watches for pilots, but they were also the first ones to utilise the iconic naval officer dress style uniform for pilots, with all the other airlines following suit.

Teddy, great job with this deep dive into GMT topic 👍

I like GMT watches. Genuinely useful while traveling 🤠

GMT complication is fascinating and very usefull. However I find the most usefull and clear is the second ring time zone

Great timing after Seiko released the GMT Seiko 5

Very interesting information, Please do a video on pieces of Greubel Forsey or Phillippe Dufour

I travel to different countries very often for work, having a GMT watch helps me a lot.

Thank you to clarify the operating mode of the GMT Watches . I will try to find details in book (in French) . Enjoying your videos, i think that there is now more watches with this GMT fonction. I will try to forget the OMEGA WORLD TIMER (wonderful) you have already shown us that we can find GMT watches for affordable price.

I use my dive watch as gmt. At first it may take a little bit of brain effort, but later it’s super easy. Sometime when I travel I just place the 12h marker on the dive bezel at the hour difference of my home town and I set the watch hands at the local time. For example, traveling from Valencia to London. 1h time difference. I rotate the dive bezel so it’s 12h marker stays at 11 oclock. So when it’s 11:00 in London, I know it’s 12:00 in Valencia. When it’s 9:00 in London, the hour hand points at (50) marker on the bezel, which corresponds to 10h. For a trip to a city that’s only 1h time difference this may sound stupid. But you don’t know how many times by mistake I end up adding an hour, instead of substracting. When I need to know the time and time difference quickly without looking at my phone, I do this. After all I have a rotating bezel, I’m not going to dive or anything, so why not use it?

Thanks Teddy. Clearly explained. What is the difference between GMT and UTC? I missed that one.

i guess this whole time, I knew nothing about GMTs lol great vid!

Excellent Teddy, thank you 🙏. Now I don't have to feel foolish not knowing this quite important complication 👍😁

The names of these different types of multi-time-zone watches makes them sound a lot more different than they functionally are. It feels like a difference between A car whose back door can only be unlocked using the buttons on the front two doors vs one Who’s back doors can be unlocked independently. They’re all dual time lol

Great video. I would like you to take a few minutes to explain with examples about the World Time complication, since it confuses me when it is daylight saving time and the configuration of the cities on the bezel or rehaut of the watch.

Very thorough explanation! For me living in the US, and only really caring about other time zones in the US, the simple 12-hour rotating bezel is my best option. I just wish there were more watches out there to offer a 12-hour bezel.

Nice video, but I thought you made a video on this subject already. Thanks.

the last watch is simply amazing, unimatic? what serial? great content man

Great video, but you should have mentioned the best dual time solution created to date - an extra two hand dial that can be set independently. I love my GMT watches, but I am forced to admit that my inexpensive Zeppelin has the shortest "time to perception" compared with my office and traveller GMT watches.
