Mainspring winding set from Bergeon, or not?


Recommended Posts

Greetings to everyone, 

 

Recently there was this nice watchmaker festival, and while looking around I stumbled upon this nice little mainspring winding set. The price was right so, I couldn't resist from not buying it. 

On the box and on each tool says Bergeon, and the kit looks like it was never used, some parts even covered grease. Googling did not bring much results, if any at all. 

 

So I'm just wondering, is this a real deal Bergeon winding set, or a modern reproduction of some sort?  Does anyone know?

 

Thank you!

It's 100% Bergeon. Well.... Bergeon had it made. I've owned probably a dozen sets of these, some marked Bergeon, some no name, but clearly from mid 20th century. Identical. There are little nuances, also between Bergeon sets of the same period. Definitely Swiss in any case.

 

The big change on these was when they started making "Nivaflex" sets. The only real difference is instead of a hoky (usually too long) hook, the hook is "internal" to the arbor. Basically machined in, on a spiral, like a real barrel arbor, instead of being whacked in raising metal with a punch. I think it was to accommodate some of the unforgivingness of modern alloy springs being stretched out. Caliber specific winders soon followed, as the trend became to make barrel arbors smaller to allow more spring length, and the old standard winder arbor diameters proved to be too large.

 

I might have this identical set- will check tomorrow when in the shop. I like that a lot of folks back then wrote the date purchased under the lid, I think the set I use most is marked 1943 😮.

Wow. So it's more of a museum piece than an actual tool?

If all the vintage tools that watchmakers are currently using were to disappear because it's a museum piece watch repair would cease to exist. Vintage means nothing to a watchmaker that is a very usable tool.

That's my main set, was off on the date a few years. And another set with the same info sheet as OP, I think the quote in German is something like, "if you want good health, don't take pleasure in good things", maybe someone is more fluent here?

Pretty much correct, according to my German friend.

Who wants good health, should enjoy good things not to much. 😃 

Funny. Tell that to the guys with APs, Rolexs and so on... just kidding))) 

Cool sets btw! Thank you for sharing.

Seeing as how most of my tools for jeweling and staking were purchased from antiques dealers this is wise…

    • Hi Frank and Thanks for the suggestion, Sorry I may have worded things incorrectly. The ac122 is no good as it only ran for 5min, I am looking for the same germanium transistor that was used on the w726 movement back in the '70s or a modern equivalent as i believe it is the missing link for a working clock again. Do you or anybody else on the forum have some idea as to where I might find such a transistor? ... I see you are in Germany and that is where Junghans originated from so I have my fingers crossed.🫰👍 Cheers AL Cheers Richard ... Thanks Cheers Nucejoe ... Thanks
    • If you loosen the screws of the top plate and spin it with the turbo, does it improve?
    • So, I said when i used one of these balances I would provide an update. Do they work? Are they legit? I'm still almost 100% confident they are real just based on clearly being from the same tooling but possibly factory seconds likely with minor cosmetic defects. The one in the photo here which has a little hair trapped under the hairspring is the one i used.  Did it work? Boy did it... So the 7s26 is not exactly famous for being a high accuracy movement. From the factory a delta of 10 to 20 is not exactly uncommon. I put the balance in and the bone headed design of how seikos stud is made it's almost a guarantee you'll put a slight twist in it when you install it that you have to correct and that's what happened. I corrected the twist and like with all seiko balances had to do a tiny bit of correction on the terminal curve to make sure it perfectly tracked the open regulator pins and stayed centered.  I then closed them up and did my final timing and adjustment.  On a 7s26C with the balance from sofly i got a six position delta of ONLY FIVE SECONDS. Which is a tie for the smallest delta i've gotten on one of these movements.  It's been in a 7s26 on my wrist now for 8 days and has lost three seconds. Not PER day, 3 seconds in 8 days total. Based on my experience now i'm confident enough to buy these and I will likely order some more very soon.
    • Just my rotary tool with a muslin buffing wheel and some green Dialux.
    • Okay as somebody totally unfamiliar with old swiss stuff does this look normal to you guys? So theoretically this thing was serviced by a professional of dubious qualifications 20 years ago, sat in a drawer ever since and so I figured the barrel should be serviced and the new mainspring i would hope he'd have put in there would probably be usable (I have a new one anyways ready to go.) but i'm not really sure what i'm looking at here.  There's no bridle to speak of on the mainspring, it's just folded over at the end.  Inside the barrel is a second part. I've never seen anything like this but that folded over part clearly hooks onto it.  I have a brand new GR mainspring for this movement ready to go if i have to replace the mainspring. Is this an integral part or is this something strange the previous watchmaker did? It looks like the bridle is just a separate part of the spring itself. If the new one i have has it's own bridle i'm wondering if i even need this part.
