When the power is out, mechanical and manual devices are what we fall back on. Astronauts have them for this reason so do pilots and seagoing navigators.

[@felixs.7243]

If I had to choose a single Chronograph to own, it would be my vintage Sinn 156 Military Chronograph with a Lemania 5100 calibre. My father gave it to me a few years ago and I wore it almost everyday for years. He is in the Bundeswehr (the german military) and used it as a legitimate timer for his job as a artillery officer. It's 30 years old and saw real use, both in normal training, but also in actual missions, as it was with him in the Kosovo-conflict. It's my favorite watch and I will always cherish it.

[@louiscyfer6944]

i would choose the bulova 97b122

[@jaimerivera2545]

I would choose my Croton from the 70s, with the Lemania 1340 in which the 5100 caliber Is based on!

Cool story bro, this is very helpful in helping me decide on my next chronograph

Man, that's some history. KEEP it and give it on to someone in your family :)

I own the mentioned Breitling Rattrapante and am totally in love with this piece of art.

[@CharlieHustle1687]

By watching Teddys videos along with some others religiously over the course of a year and a half, I’ve educated myself. By doing so, I didn’t waste money on trendy or fad watches like a lot of people do while starting this journey. I started with a Seiko 5 and have grown to many more watches. Thanks Teddy!!!

[@jonkonig]

I have done exactly the same as you. So happy I researched and learnt about watches and didn't waste money. Started the the trusty SNK807

[@greiggwilliams776]

Same! Seiko 5! Perfect way to scratch that first mechanical watch itch. While you learn more

Dang guys those are nice, thanks for turning me onto those.

hey, mine too!

[@TCW838]

Thank you. As a newbie, I have my first chronograph (Ball train master II cannonball) as of this month so your videos a a great learning tool for me.

[@TeddyBaldassarre]

Happy to help 🙌🏻

Cool watch!

[@kencrumb5291]

Every time I watch one of your videos I learn something new. You're the first person I followed when I started really developing a passion for watches and you're always the first person I view when I get notifications on my phone. Keep up the great work.

[@TeddyBaldassarre]

Appreciate it, Ken!

[@yuvalalon9508]

I pick my Omega Deville rattrapante 44m on bracelet. Love it!

[@YoussefAbdelaal]

I've just acquired a Glashütte Original Seventies Chronograph Panorama Date, and I'd choose no other chronograph watch! Many people won't know this model or care for the brand. It's a steel sports watch with a flyback chronograph in a bi-compax configuration and an integrated bracelet that can be swapped out for a leather or rubber strap, and a discrete power reserve indicator. I think GO's panorama date window is a rare example of a properly executed date complication that isn't just an afterthought in the form of a tiny window at the 3 or 4 o'clock positions. Thanks for making me feel a bit better about this watch's 14.1mm case thickness!

[@Not_Mark_Twain]

Excellent primer. I don't personally get enough joy or utility from a chronograph to justify the increase in fragility, cost, thickness, and service complexity but I appreciate the background info and candid assessment of why these watches have their fans.

[@24934637]

My first chronograph was an Accurist quartz reverse panda dating from about 1990. I was given it as a birthday present for my 15th birthday, and amazingly it's still working fine! The abuse it suffered was beyond what most watches could cope with, as for a few years I was working as an outdoor activity instructor, teching rock climbing, and taking groups on walks up a river gorge, constantly wet and getting bashed against rocks, it's been very lucky to survive! Nowadays I've got a Doxa Sub 200 C-Graph if I need a chrono, but it's not a watch I use often.

[@chateaubullion2560]

This was so informative. Thank you. I only have one chronograph watch. The Omega Speedmaster, caliber 1861 with hesalite crystal. To me this is "The" chronograph watch.

[@andrewffay]

I got an Omega Speedmaster Racing (44.25mm) with the silver dial with orange accents and brown leather band this last week and I absolutely love it. Having the display case base is great, and the 9900 caliber movement from them is pretty amazing. Thanks for all of your great videos - I watch almost daily!!

[@Jcrpdx]

Every watch shown is a beautiful work of art that is with you all day long. Your videos are fascinating. Thank you. For me a watch is very practical. Pulling a cell phone out of my pocket is inconvenient and in meetings, rude. I also use my chronograph to help me stay focused by inconspicuously reminding me of time spent on each task or meeting. And even in the lower price categories that I can afford, it's an attractive accessory for both formal & casual outfits. And for those who have more disposable income, it's also a personal and portable art collection.

[@stuartizon]

Timing making my pour over with a chronograph - best way of combining my love of coffee with my love of watches 😀

[@christophersmith108]

As far as a chronograph for its chronographic function, then the Zenith El Primero 21 has to be my number one. However, if this was a giveaway "Choose your favourite chronograph" question, I would probably go for an A Lange & Sonne Datograph Perpetual Tourbillon! Thanks for the continuing run of interesting videos. Whenever KZbin tells me that you've posted I seem to be able to find twenty minutes to stop whatever I am doing and watch right away!

[@DavidWoodsGuitar]

Easily the best chronograph video I have watched; extremely informative. Thank you, Teddy.

[@sgtpluck8344]

I love mine as a daily wearer. I's great-looking, great size, comfortable on the wrist and a real conversation piece. Should be a part of every watch-lovers collection.

[@paulfreudman4577]

The one and only, the Iconic Omega Speedmaster Moonwatch is my first and only choice for ultimate chronograph

[@Danny-fs1hk]

Teddy is a good teacher; covering practical applications and historical references too.

[@Hard_7_Iron]

Thanks for this video. My Omega Seamaster is also a Chrono (1999 / 2000). But my favorite Chrono is the cheapest. Timex 1854 Flyback. It’s my Friday and Saturday watch. Years ago while in Asia, I fell in love with a rubber band with clasp..it didnt quite fit. The attendant in the kiosk grabbed her magnifier and started carving away rubber until it fit perfectly. All Black (watch and band) with the tan dial markings. And EVERY Chrono function is in about a 150 degree circular shape, rather than the normal, much smaller 360 degree types. I don’t know why I love this watch so much. But I do enjoy wearing it for over 8 or 9 years now. EVERY Friday and Saturday. Thanks for the hard work man….we appreciate it.

[@Mauricio.Solorzano]

I got a Daytona Panda a few years ago after waiting some time, and honestly, that's all the chronograph I will ever need. It is very thin by current standards, and is incredibly accurate. Yes expensive too, but it is a time piece that my son can inherit and can think of me when I am long gone.

[@ellmanncayetano5551]

Thank you for uploading this. TIL what Chronographs are for. I only like them because of aesthetics and never really bothered what they are for before.

[@guillaumemichel3156]

I researched chronographs for a few months and recently bought the Longines Master collection L2.629.4.78.3. Stunning elegance of the dial with two subdials at 3 and 9, thin hands made of blue heated steel, inside a 40 mm case, and a brown alligator strap. The classic, refined and somewhat simplistic look of this watch makes me think I can hold on to it for many more years than other chronos with bolder design choices or busier features.

[@Z-Man1973]

Thank you Teddy for this very informative video on mechanical chronographs. I've only ever owned one chronograph, and it was a quartz model. I appreciate all the detail you discuss, and there was a lot discussed in the short 19 minutes here. I'm sure you could have spent hours on this topic. Being still relatively new to horology, my most desired chronograph to add to my collection is the Zenith El Primero Ref 032040400/69C494. Looking forward to you next video.

[@allenmurrell]

Recently looked at a new speedmaster. Beautiful and iconic. Then I looked at a zenith defy 21 skeleton chrono. Holy crap. For the money, I don't know what could beat it.

[@stevefox8605]

Had a couple, the Chinese pilot one & a Hamilton x wind (7750). Very cool, but never used the chronograph function ( about as useful as the rotating bezel on a diver for me) & tho I loved the build quality and accuracy of the Hamilton I sold it quickly before it needed an expensive service... Love them aesthetically but ultimately expensive to run & useless for me. Pick one? Gotta be a Speedmaster, the ultimate iconic timepiece. Good episode, thanks Teddy 👍🏻👍🏻

[@anthonystevens8683]

A very well put together explanation of the mechanical chronograph Teddy, arguably one of the best that simply describes the cam v column wheel and lateral v vertical clutch options. I'll only comment on chronographs that I have seen in the flesh at the AD or than I own. It's a tie really depending on form or function. Both are Omega Seamaster chronographs, the current wavy ceramic dial with two sub dials and the previous three sub dial versions based on the heavily modified Valjoux 7753 movement. For form the current version takes the win, the minute and hour chrono dials are integrated into a single dial that looks like a clock and very easy to read at a glance to get a rough view of elapsed time however reading the exact minute is less easy given it has twice the graduations than a thirty minute counter. That ceramic dial is also fantastic to look at. The old version wins for function easily, all chrono hands are red, all hands on the watch carry lume and it's for my eyes anyway easier to read the elapsed minutes. I guess this illustrates just how a new model can move forwards and backwards at the same time. As yet I still don't have a Speedmaster but that might take an overall win.

[@Ratchetfan321]

New fan and dont really have the best watch collection but love learning about them.

[@nmfl100]

I get your comment about the chronograph being mainly a romantic object today, but I'd say the wrist chronograph is still relevant as a tool. No phone or gadget replaces the usability and practicality of a chrono.

[@pgong]

Agreed. The start/stop button is immediately accessible. No have to pull out a phone, unlock, launch an app, etc.

Another great video. I would 100% go for the Omega Speedmaster with the Navy dial and Red second hand

[@engineering_guy]

Great video as always Teddy. I've been watching some of your videos where you say at the end that wearing a watch or having certain complications is now mainly for style or fashion or for the enjoyment of having something complicated on our wrist. I would like to add my opinion...while i do understand that we have smartphones for almost everything, nothing beats the convenience of having a chronograph on your wrist. Smartphones are bulky. If I have a phone on one hand, then essentially i can't do many many things i would want to time. A bike ride for example. The sheer convenience of having a timing machine on your wrist is still unmatched in my opinion ..for the cases where you need both your hands free and ultra precision is not important. Same i would say for timers also. I greatly value the watch on my wrist..not only as a fashion statement..but as a genuine tool which would make my life difficult if i didn't have it

[@manishsoni7689]

As always, another informative presentation on one of the complications I enjoy and 'appreciate' with wristwatches. One question I have is, wouldn't Hanhart chronographs be worth noting in the video being known, I assume, for their history with this type of complication? Your thoughts on this, Teddy, and again, superb topic and video.

[@jolness1]

If I had to pick one specific chronograph, would be the Tag CAF2120 Aquaracer Chrono that was my dad's only nice watch for many many years. I grew up wanting one like it and I think it is a big part of my love for diver style watches. That and my uncles no date Submariner. I know Tag gets a bad rap these days but that watch has a special place in my heart. I believe it has the Calibre 16 (7750) but it doesn't say so on the dial like so many of them do. It held up well. Dad isn't really a mechanical watch fan, just wanted something fancier but was too thrifty to spend the money for a Sub (accountants lol) at the time. It lasted 12 years without service before it had issues (cannot remember off hand what it was) so he sent it in and had it serviced. Doesn't get a ton of wrist time these days so once a month, I wind it for him and wear it around for a few hours when we come over for dinner or something just to make sure the gear train moves around and distributes any lubrication.

I'll never own one, but I dream about the Zenith El Primero. Longines is killing it. That "tuxedo" is so beautiful it could make me weep. Obviously, the Omega Speedmaster is one of the most iconic watches in history. (I can't afford that, either.) I understand it's not "cool" to say anything good about Tag Heuer, but I have always enjoyed the Monaco. Given the realities of my wallet, I think the Hamilton and the Tissot Heritage are very cool.

[@jorgenewport-jones858]

I love my Tudor chronograph Tiger Woods edition. And I also love my Hamilton PAN ERUP chrono.

[@drnick40]

Thanks Teddy! I personally like my Zenith El Primero. It is accurate, good looking and is the thinnest in that category. My model has 100m water resistance so I can wear it all the time without a fear of getting the internals wet. And who can beat the looks of the movement and it’s 36k beat rate. Last but not the least, it is El Primero - the first integrated chronograph movement and the one not anyone but Rolex closed to drive the Daytona. Tons of heritage there. I also have a B01 Breitling, a Speedmaster and a IWC chronographs in my collection but I like the El Primero the most.

[@carllange3950]

Excellent video. The tachymeter scale can be generalized to units-per-hour, not just speed (e.g. mph, kph). I have a vintage pocket watch chronograph that has printed “PRODUCTION PER HOUR” along the tachymeter scale. Quite a few of my vintage stopwatches have decimeter (1/100 minute) scales instead of measuring seconds. This makes for easier calculations when doing manufacturing time studies. My first watch from 1971 was a chronograph. I stopped wearing it when I could not justify spending three times the purchase price to have it serviced. My only modern mechanical chronograph is a Bulova with a Valjoux 7750 movement. Realistically, quartz is far more practical (and affordable) for chronographs.

[@MrKimmuriel]

As a chemist I prefer ana-digi chronographs with independable second hand (and also independable timer for countdown). It shows readable distinct values, and it's usefull in very short timings. Also titanium - preferable as inert material. It's a pity, swiss brands rarely develop these product lines. So we have limited choices. My temporal grail now is Citizen Promaster Sky JDM PMV-65 2271: solar, utc, e6b, tough covered titanium, serious water resistant in 20 bar (for shame, Omega Skywalker ;), good lume, bracelet with good quick-adjust system. It's a good beater indeed. Pick another? Hamilton Khaki Flight Timer (next year), some Breitling?

[@mendipfox1650]

Really interesting video. Thanks. I’ve just added a new Omega SMP300 Chrono to my collection. It’s got the 9900 caliber. I’m absolutely shocked how accurate it is.

I chose the Omega Speedmaster Pro MkIV 45 years ago (Omega cal. 1040, a modified Lemania cal. 1340). One journey back to Bienne for a touch-up and still going strong, keeping exceptional time. They don't make them like that anymore. In second place, I'd choose a 1986 TAG/Heuer 510.500-12 with the Lemania cal. 5012.
