Piaget bumper???


Recommended Posts

Morning all

 

I was wondering if anybody could shed any light on this movement if possible. The watch dates from around the 40s or 50s and I’m not sure if this is period correct for this watch. I have seen similar looking watches housing an AS1250 movement stamped Piaget but this looks to be different. My inital guess is this has lots of replacement parts but I’m no expert so was wondering if someone could help.

 

Thanks guys

That appears to be an AS 1171 which would fit with the your dating i.e. produced up to about the mid-1940s.

Looking at Ranfft does gives production for the 1171 spanning 1935 to 1945 whilst for the 1250 it's 1940 to 1953. If you've seen similar watches to yours sporting the latter it would indicate yours is an early model that used the earlier movement.

That would make sense as I have been told the printing on the dial “fab sussie” would be indication of an earlier model. Thanks for your help it’s much appreciated

Out of interest what condition is the dial in given the age of the watch? The case, at least from the back, looks to be pretty tidy.
BTW this is a good set of pics relating to a service of an AS 1171 you might be interested in: https://watchguy.co.uk/cgi-bin/library?action=show_photos&wat_id=3006


Yes the case has only a tiny dint on the back of one of the lugs but apart from that it has only light scratches and I also believe that it’s unpolished but I’m not expert. I’ve attached a picture of the dial and would love to hear your opinion on it.

Cheers & thanks for the link to the AS1171 service

Ah ... so it's actually an AS 1172 as it has a sweep hand rather than a sub-second hand. Same movement in the main as the 1171 though.

The dial looks amazingly fresh ... the first thing that stands out is that the Piaget Automatic script looks a lot fresher than it has any right to on a 75 year old watch! But it could just be that Piaget used good quality materials and that, based on the good condition overall, this watch has only been used on special occasions and kept in a dry dark place normally that preserved the dial.

Nice watch. :)

Nice watch. [emoji4]

Oh interesting. I have sent some pictures to Piaget to see if they have any information on the watch as I don’t even know the reference number or anything else about it and would love to have a little more information. I have no reason to believe the dial is a forgery but if it was I wouldn’t even know to be totally honest as the brand & age of the watch are out of my expertise, hopefully Piaget can shed some light on this matter....

There's nothing to suggest anything about this is a forgery.
You might have already come across this in your research: https://watchcharts.com/listing/599135 Same era, same font around edges etc.

Sure, no I have not come across this during my research so thanks for that. it certainly does display a lot of the same traits doesn’t it. I’m having trouble finding out if similar models also have fixed bars between the lugs as mine does but I’m guessing there would be different variations between the models anyway. aesthetically I find the watch very pleasing but until some of these questions have been answered I don’t think I will be able to fully enjoy the piece as I’m a sucker for knowing the history of my timepieces.

Cheers

    • Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.
    • That's a good idea - shrinking down the nut and wrench size from the old casebook trick!
    • I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.    
    • I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.
