We know you want more watches…. click here: linktr.ee/watchfinder

Being able to work this around your friends when you need to split the bill at the restaurant will guarantee you some heightened sense of superiority.

My experience with such bezels are limited to "ooooogh... It turns!"

Being an airline pilot, I must tell you few things... That’s one thing you must learn as a pilot for calculations by an E6B slide rule. Unfortunately getting bloody old you can’t see a damn thing on the bezel... Cheers chaps. Ps : excellent review .

Can you imagine at the next dinner party explaining all this to the girls. I hope they'll be impressed.

It's incredible how much knowledge is lost in one generation. My dad was an engineer and I had once opened up his old trunk containing engineering books and yes, a slide rule. Never understood how to use it and it pains me to think I'll never be able to explain it to my kids without resorting to a KZfaq video. Great explanation on the Navitimer; I've newfound respect for traditional timekeeping.

Exam today: Teachers tells the whole class to put their smartphones on the front desk and take off their smart/apple watches. Exam in the 1950's/60's: Teacher tells the whole class to all take their Navitimers and chronomats off.

Someone actually knows how this watch works?!? Madness.

10/10 didnt understand a thing.

That Breitling is probably the most beautiful watch I have ever seen.

No wonder plane crashes were much more common back then... this is far worse than texting while driving!

Now I see why these are called "Complications"...

I'm studying Commercial Aviation at UND and when I heard about this watch, I immediately took out my E6B (aviation's version of a slide ruler) and lo and behold... that watch is pretty much identical.

Your video's are always compelling. I'm 51 years old; a little younger than the slide rule generation, but loved the things and learned how to use one when I was young but am rusty now. They give you more of an idea of how numbers work than a calculator because you can see the correlation. I bought a Citizen Navihawk because it has a slide rule bezel although I've never used it (plus my eyesight is making it more difficult to make out...) Looking forward to your next release! Thanks!

This guy: takes an hour to explain all this stuff The other guy: bro, I all wanted was to know the time

As a submarine navigator I can appreciate the demo. We used a weems and Plath slide rule to perform many of these calculations. It was quicker than using a hp scientific at the time and far quicker once you got the hang of it. The navitimer is a time saving manual computational device. Very cool indeed.

I must say. As someone working towards a career in aviation, a horology enthusiast, and a person who likes more "old school" instruments, this is absolutely amazing

Yeah.....I’ll use it to tell the time 🤣

I must be weird, the very complexity of this thing has suddenly made me want a Navitimer when, previously, I had zero interest in Breitling as a brand! I have vague memories from the 1970’s of a cousin who used a slide rule regularly....I was very impressed then and would like one of my own!

I had to watch it several time with pauses in order to wrap my head around it, genious.

I 'tried' to use one when I was flying regularly, I say tried, i knew how a slide rule works, you had to getting a pilots licence in the 80's it was part of the syllabus, but trying to use one of these in a cramped cockpit, with no autopilot and a lot of turbulence is near on impossible. in the last 30 years the only time i have ever rotated the bezel is when when OCD gets the better of me and i've re-aligned the 60 back to 12' o'clock after its rotated due to putting on a snug sleeved coat or reaching into a bag etc...

I wish I had this in 6th grad I could have cheated in the class tests

As a NASA navigator I can appreciate the demo. We used a weems and Plath slide rule to perform many of these calculations. It was quicker than using a hp scientific at the time and far quicker once you got the hang of it. The navitimer is a time saving manual computational device. Very cool indeed.

Used it all the time when I used to flight instruct. On a Casio.

8 min of pure pleasure! Thank you!

I have a new appreciation for these watches. Amazed by the skills and hands who made these watches decades ago

Thank you for this most instructional video! There are people who try to explain the Navitimer 01 functionality and fail miserably because they don't show a detailed enough example with a zoomed lens as you've demonstrated. Also I appreciated the different examples. +1

Love the video but may be a dive watch Is more suited to my intellect

THIS - IS - GENIUS Navitimer goes with me on every math exam since today!!!

Me: I am too old to do math in my head Watch: You are also too old to watch the results on the watch.

After this, I still don't know how it works.!

Most people don't know how to use the E6B tool, and most pilots will tell you they never even need to. This is mostly true nowadays, but I can say that my E6B AOPA watch was extremely helpful on my multi-engine commercial checkride. The checkride began with a VFR cross-country diversion and I was told to utilize my E6B before checking my calculations with the garmin G430 in the plane. The only problem was that I forgot my E6B in my flight bag in the rear of the aircraft, well out of my reach (it was a Beechcraft BE-76 Duchess). So I simply used the E6B on my watch and got the numbers I needed. They checked out when compared against the G430 and I was able to continue (and pass) my checkride. Failing would have set me back quite a lot of money, so I was very glad I had my E6B watch with me that day. I still wear it, even though I am now flying Embraer E175s and will likely never need it for work.

The navitimer is an exquisitely beautiful timepiece. I’m in love with this watch!

Since you are reviewing pilot watches do a review on the legendary Longines Charles Lindbergh Hours angle. If they got burned by the Navitimers slide rule imagine the Astronomical almanac and the meridians... Thank you indeed for all the exceptional watches that you are reviewing .

All student pilots even nowadays have to learn how to use an analogue circular flight computer, which is exactly what that watch is; Amazing. Great video!

I think for the modern pilot this watch still has some use. Currencies conversions is one. Litres to gallons is another. Also knots to statue miles per hour and kmh. And of course it looks pretty damn nice. Ideal for gross error checks etc.

My life feels less complicated now! One of my desired watch. ⌚

As a Mars Rover I can appreciate the demo. We used a weems and Plath slide rule to perform many of these calculations. It was quicker than using a hp scientific at the time and far quicker once you got the hang of it. The navitimer is a time saving manual computational device. Very cool indeed.

The quality and content of this channel never ceases to amaze me - I bet 99% of navitimer owners don't understand how to use it . .

My late father made all his engineering calculations on both short 6inch and long 1foot slide rules in the 1950-70,s I never got past the basics but he worked out geometry and sin and co sine stuff that was way beyond my tiny mind

I kinda lost you at "It's a complicated mess" ... my dad used a slide rule back in the day .. and I understand the idea of it but I've no idea what the hell we're supposed to be looking it. But I appreciate the attempt. I'm buying the Sinn 903 Navitimer (a licensed version of the Breitling) .. which has all the mess too .. so I'll have a lot of practice with it.

Nothing beats the slide rule bezel. This is what innovation is about. Always in love with the navitimer !! :P

Make a video about how Watchfinder and Co. came into existence, or maybe behind the scenes videos. Your videos may well be as luxurious as those watches you present here. Love the art!

These are amazing mechanism. Credit to the maker. I understood what it’s for but did comprehend how to use it. Despite how well it was explained. I’d have to buy one and practice. Excellent

Funny how much has changed in the last 50 yrs or so. My father was an engineer and I went to engineering school in the late 60s. If I wanted to forget how a slide rule works, I’d have to get a pre-frontal lobotomy. 😆 I knew how to use one before I was 10, used it a little in high school, and I virtually ate, slept, and brushed my teeth with one in my hand 😉 in college. If you understand logarithms, it’s easy as pi! 🙄 I would eventually like to have a watch with a slide rule bevel in my collection, just to play with from time to time. 🧐

Now I want one of these.

This is fascinating. My father has a Navitimer and is a hobby pilot, I must show him this, he certainly doesn't know all of these features!

I've been wearing a Rotary Aquaspeed quartz for years, a cheap and fully functional slide rule bezel watch... And I never knew.

While you were out partying I was mastering the ways of the n a v i t i m e r

Can the it calculate how many times I need to watch this video before I can understand how my Navitimer works?

Thank you for being the best Watch channel on KZfaq! Good to see you aren’t pushing Squale on everyone!

The Navitimer has always been on my top ten list

Really well done. Thank you so much. I love my Navitimer. I have the Blue eyed Black.

This watch is such a beauty. Totally my style 😍

I took ground school and it took us longer than 5 minutes to learn how to use the B6b slide rule. Amazing you did it in such a short amount of time.

Just ordered mine. What a blast from the past. In the mid 1980's I think we were the last kids in high school to learn slide rules along side of our scientific calculators.

This was so stressful lol! Sticking to my iPhone for math.

still a complete mess for me tho. i think you really have to spend some time with it. But its rather useless in the time of smartphones. the most usefull feature in my book is a gmt function with a roatating bezel to display 2 timezones. that comes in pretty handy but again so does your phone.

I"ve had my navitimer for 5 years (well, almost) and had no idea how it worked - thanks for this! LOL

I’m a private pilot and avionics engineer and own a Navitimer. I’d personally prefer to do the math on paper as I’m way faster with the arithmetic then using the E6B on this watch but I have to give kudos to all the pilots that have flown in the earlier days when a calculator isn’t easily accessible. I know some airline pilots still use the slide rule on the watch but it takes time to get familiar with the indices and a little logic behind the decimal placement.

That's so cool! I've never wanted one more than now. Alas, they're so big.

I'm more confused now than before I watched the entire video.

I always looked at the watch with a question mark in my eyes, but now I have two light bulbs. Thanks for explain one of the watches consumer mysteries

video starts at 3:23

Er no! My Brain has just imploded!

You lost me at “rotate bezel”.

I’ve been wondering about these. To me this is just the perfect looking watch. Just wonderful

3:58 setting off my "hey Siri" 😂😂

the only problem is, imperial units...

Mile High Club

My eyes glazed over almost instantly when the figures started flying.

Your narration is ridiculously good.

Imagine spending thousands just to calculate 9x12

Always a high quality production and narration with all your videos. Thanks

I work in R&D and use the chronograph and dial for quick calculations on a regular basis. It generally beats the colleagues and their smartphones in speed: the expression on their face is priceless!

I have a Citizen ProMaster Eco Drive which dose the same thing but you have separate knob that you turn and the flight computer turns inside the glass so no need for a Bezel on top of the glass , had this watch for 10 years now and it has never let me down still going strong.

Now I know what video to direct people to if they ask how my watch works.

Best explanation of a Navi timer ever!

I am more confused now that I have watched the video. Your explanation is SUPER clear, I just lack brain cells I think

its very impressive that before any computer existed, people calculated log by hand and get the correct markers' spacing for slide rules and rings.

It's, basically, the circular "E6B Flight Computer" shrunk down to fit in a watch bezel. The E6B is carried around by pilots and student pilots during flights because electronics can fail for any number of reasons, and usually at the least convenient times. Laminated cardboard (the E6B) doesn't have to worry about, say, the power going out. Failure, case-in-point: During the Apollo 11 moon landing, the electronic mission timer in the lunar module failed. Neil Armstrong left his _purely mechanical_ Omega Speedmaster behind, during the lunar excursion, to substitute for the failed, electronic timer.

Thank you for the video. That was amazing. One of my favorite watches. I will watch a couple more to understand how that works.

What's the third marker between NAUT. and STAT.?

This timepiece is for the serious navigator or aviator. It is really a technical instrument.

I’m in my late 60s and grew up using a slide rule for math/science subjects. One of my last devices before the advent of quartz calculators was a circular slide rule. Very compact and easy to use. I’d love to try the Navitimer for old times sake - pun intended!

First. Obtain a slide rule you may acquire in Ebay. Seriously, you can still acquire that relic . Go over the available videos , learn and practice. The do have circular slide rules too. Once you pick up the technique the timepiece sliderule is seen as a clever tool. The air force pilots and naval aviators might still be learning this material and still by time pieces that have these features.

Simply the BEST watch channel hands down

This enigma was in the back of my mind refusing to die since the early 90s!

If it's used by pilots, why is it named Navitimer? Not maybe skytimer. Forgive my ignorance, the Navi is from Navigation not Navy

When electronics fail, for some reason (battery loss, flood, electromagnetic interference)... get to basics is a good backup plan.

This is by far the most aesthetically appealing watch ive ever seen.

It’s not just how flying used to be done, during your flight training you use a flight computer which is literally just s larger version of a navitimer! I remember my first diversion I had to calculate in flight using a flight computer 😂

Wow. There I was just using the slide rule for simple stuff like multiplication, division and miles-km conversions!

Watched 20x. I know the dial moves. The end. It's amazing. And I'm depressed I didn't understand a word.

This is what we pilots call E6-B calculator. There is a reason pilots like me and others don't use this anymore. They don't even teach new pilots this. The watch would be cool in the 50s or till digital calculators came along. Now as he said its just a mess on a watch!

I used a whiz wheel for 3,000 flight hours to calculate fuel burn and time on station available. Once you get the hang of it, it’s faster than any calculator

Great job! I've seen circular sliderules but not the watch, Beautiful piece!

I’ll admit I thought that this watch was just a hideous mess, but this really is very clever! Great explanation.

This watch, in this spec and color is probably my dream watch.

Incredibly detailed and useful video. Thanks for the help!
