A Monopusher Longines Conquest Chronograph!

[@Mike-bg3cf]

Stian, you probably don't remember but I said earlier that I watched your servicing of Longines 30L repeatedly on 1/4 speed, rewinding and rewatching in order to get an basic understanding of a simple watch movement without complications. Well, I just watched the section of this video between 1:44 to 2:06 on 1/4 speed probably 50 times over as you operated the pusher mechanism in order to understand the movement of the springs and levers as they interact and cam in and out of the castellations on the pillar wheel to disengage the clutch wheels and release the hammer into the cams on the minute and the second hand wheels to reset them. This would not have been possible without the great camera work that you do on your videos. Thank you very much for the great work. Thanks to you I can now say that I have a basic understanding of the single pusher chronograph mechanism.

[@VintageWatchServices]

Thanks so much for telling me that, Mike, that's really nice to hear :) 😊

[@randyallen2771]

Great video Stian! This was one of your most informative. I remember seeing mono-pushers before but as I recall it was from one of the smaller German makers like Tutima or Hanhart, not Longines, anyway I found the macro pictures of the hairspring positioning and how it affects positional variation as well as the tiny eccentrics most interesting, keep up the good work! PS liked the last video too.

[@VintageWatchServices]

Thanks a lot, Randy, great to hear! I thought this one might be a bit too dry, so I'll spice it up again for the next one 😉

[@tedblack2415]

Nice piece & amazing work , chrono's completely boggle my mind , i don't think i'd ever attempt tackling one , i'm astonished as to how you make it look so matter of fact but also the experience/ in depth knowledge plus spotting and solving the hairspring issue on regulation ,such finite skill i'd love to have a fraction of .

[@-triumphgt667]

Very interesting - thank you - I actually have a very similar watch - same movement I believe but the case is very slightly different with a slight cut out between the lugs. I actually got it when I bought an old VW Polo about 25 years ago and when cleaning it out I found the watch in a fairly poor state in the boot. Had it just lying in the garage for years but got it out a few months ago and cleaned the case up and put on a new strap - it works but needs a service and this episode will encourage me to get it done. It is a Olympic Games version from 72 though serial number starts 18 so slightly later in the run and the lettering still show black so clearly not worn much! The second hand is red rather than the yellow on the model shown but I suppose that may be ageing. Would probably not have bothered without you showing this one so you have saved two watches!

[@VintageWatchServices]

That's very cool to hear! ☺️ It's certainly a watch will worth saving, best of luck with it!

Great video. I'm a huge fan of Longines and they did produce inhouse chronographs post WW2. Into the 1960's(calibre 30CH). They were pretty much _the_ inhouse chronograph Swiss brand. The rest bought in movements. Just one correction. Though it's been long thought that Breitling came up with the two pusher layout. In 1936 if I recall correctly. The same year Longines patented their flyback complication. However a couple of years ago a Longines collector found a Longines fitted with their 13.33Z calibre, featuring a flyback _and_ two pushers _and_ an instantaneous minute recorder from _1929_ Years before Breitling and indeed Longines own flyback patent application. Longines confirmed the watch and they already have a two pusher flyback chronograph in their collection from 1930. I don't know if links are ok(they're not mine. I wish! 😄)

[@VintageWatchServices]

Thanks so much for your comment! Yes, the 30CH was introduced just after the war, in 1947 and produced for about three decades.. I didn't know about a Longines two pushed chronograph pre-dating Breitling, but if that's the case, then more power to them! Longines has made so many excellent contributions to the watch world and they really deserve massive respect 👍

[@HenriqueSantos-pe4nk]

Hi Stian! Thanks for another great video and by sharing your knowledge! During the video you mentioned that Longines had not produced another in-house chronograph after WWII. Immediatly I though about 30CH. More sturdy and less refined than 13ZN. Searching the web, apparently the 30CH was launched in 1947. Is this correct or the 30CH is a derivation from other chronograph maker?

[@VintageWatchServices]

Hello Henrique, and that's why I said someone should tell me if I was wrong :) I seemed to remember the 30CH was from during the war, but you are absolutely correct, it came out in 1947 👍

Always enjoy watching you work. I see this movement is marked "17 Jewels", which as I understand it for the entire movement including the chronograph complication. Can you please tell us how many jewels are dedicated to just the chrono complication, and which pivots are not jeweled in the main movement because of this? Cheers!

[@VintageWatchServices]

Hello Jon, thanks so much for that! The base movement has 15 jewels, with the center wheel not being jeweled. The chronograph parts have two jewels, in the chronograph bridge on the train side, one for the chronograph wheel and one for the minute counter wheel.

[@boydsargeant7496]

Many thanks Stian, cool watch and great video. I’m still not confident enough to venture into the chronograph world. So more cool videos like this welcome to build my learnings. Those eccentric screws would test me. Remind me, are they only for adjustment so you don’t need to remove them if the chrono works ok? But how can you recognise them as a beginner? Ta ta.

[@VintageWatchServices]

Hello Boyd, yes, the eccentrics are only for adjustment. They can indeed be a bit tricky to identify sometimes, but the ones I pointed out are the common places to find them. The only way to progress is to break barriers 😉

@@VintageWatchServices thanks Stian. What thickness was the small plate you made up to support with the Presto tool?

Oh, it's very thin, I think 0.2mm or something. Metal is very rigid when it's a small piece, so you can use a very thin sheet.

Great video, can you confirm the most common dial positions. In the vid you said dial up, 6 o'clock up and 9 o'clock up. Dial up and 6 up makes sense but considering that a majority of people wear watches on there left arm the next most common position would be 3 o'clock up. What do you think. I am just trying to understand and learn from the masters. Thank you

[@VintageWatchServices]

Thanks for watching! 9 o'clock up is indeed one of the three most common positions, as that's how the watch will be when your arm is relaxed at your side. 3 o'clock up would be when you raise your arm straight up, which isn't very common.

[@HeikosGarage]

Hello, Stian. Man does that watch ooze 1970s. With no running subdial seconds hand I would be sorely tempted to allow the chronograph seconds hand to constantly run, but I have been told that is a bad practice because it puts undue strain on the watch. Is that true?

[@VintageWatchServices]

1970's, baby! I did feel the urge to grow my hair longer with this watch, but unfortunately only succeeded doing so wth my nosehair. A well serviced chronograph shouldn't suffer much from constantly running the chronograph, so I wouldn't say it's really bad practice, but there is of course some added effort for the mechanism to power more components.

[@gast9374]

10:45 I've got a question. Why do some balance wheels have weights, and some have not, like this one? And which is better?

[@VintageWatchServices]

The screws allowed for adjusting the balance for time and also for temperature. With newer alloyes that do not expand and contract much within normal temperature ranges, these screws generally became redundant and you will in general not see them in modern watches. However, if a watch has a free-sprung balance, such as modern Rolex's and other high end watches, there will be a few moveable weights (typically at least four) around the balance to allow for adjustments. Free-sprung balances are not regulated my moving index pins as "normal" watches are, they do not have index pins. Instead, the balance and hairspring are very accurately matched and the balance can thus be fine-tuned with those moveable weights. So in a sense, when you see a modern watch with screws or some sort of weights around the rim of the balance wheel, these are likely of a very high quality.

[@gast9374]

[@jbrou123]

How does that Timegrapher get its signal? Does it 'listen' to the ticking? Do you have a video on what the numbers mean? Rate, amplitude, beat Error, etc.? With all the complicated tools and equipment needed to service movements, it's oddly satisfying to see you clean delicate parts with a wooden dowel. With the miniscule amount of lube you use, a vial of that stuff probably lasts a lifetime.

[@VintageWatchServices]

Hello Jason, the timegrapher indeed has a microphone that detects the ticks and the tocks. I talke a bit more in detail about the readings in this video: kzbin.info/www/bejne/npyuZ5hqqcdoh80

[@ygrbooks]

Dear Stian, thank you so much for another most informative and beautiful video of a very cool watch. I have a question regarding chronographs: many years ago I bought one with date, moon phase, seconds, minute and hour counters. The brand is totally unknown (Georges Claude) and it comes - so I was told - with a movement very similar to that of the Valjoux 7758. The seller told me never to let the chronograph run all the time. This is a pity, since the watch really looks cool with all the hands moving. My question therefore is: why is it not a good idea to let the chronograph part of your watch run for an extended time? Any answer would be greatly appreciated.

[@VintageWatchServices]

Thanks so much for your comment! 🤗 The real wear on a chronograph is the starting and stopping of it, so letting it run constantly wouldn't really be a big deal. It's thus not really bad for a chronograph to be running all the time, it would just mean that the mainspring has to power a few more components and potentially that you would have to service it a little bit more frequently, although that can also be disputed.

[@ygrbooks]

@@VintageWatchServices Thank you so much for your answer. I will now watch the many moving hands with less worry.

[@ralphferrara5152]

Nice watch. 👍😁

[@RyanBuchmann]

If a watch is declared to be "shock resistant," what additional features/enhancements do you notice in the engineering of the watch movement?

[@VintageWatchServices]

Hello Ryan, mostly that the balance has spring-loaded cap stones. The balance staff has the thinnest and thus most fragile pivots, so those are the most important to protect against shocks.

[@El1988Che]

Awesome video! I love everything Longines haha. However, I noticed something and I'd love to understand. When you speeded up the video to X60, you could see the crown turning!!?? Is that normal? How did that happen? Great work nonetheless!

[@VintageWatchServices]

That's indeed funny to see! The reason is that the crown was pulled out to set the time, which means that the stem was connected to the time display train and thus would revolve ever so little as if setting the time very slowly. With the crown pushed in, the sliding pinion disengages from the time display train and the crown does thus not move. But it looks very cool in the video 😂
