Hello wise ones.

Please can you tell me a name and part no. for this?

It's from ETA 2783 but the pdf I have has no match.

 

Am I even likely to be able to replace it?

 

Many thanks

 

Tim

Is it an adjustable stud holder?

As in regulator stud?  then yes. there is part 2 to it, a pointer that sits over the top of it. 

you'll notice the teeny pin where the brass circle is has snapped off. Hence the need to source a replacement.

I think, others will correct if wrong, its part 375.

hmmm, 375 is the stud holder on my 27xx variant sheet.

on cal no. 28xxx  it's part 303/2

 

Hoping my local friendly watch maker can dig something out from his mountain of spares!

Have you looked at the 2750 its the same family and listed as part 307. I think it will work but not 100 %

Indeed. I stand corrected which is not unusual [emoji4]

Found a better clearer parts list for whole family.

Shows 307/1 for that part.

Sorry TPT [emoji20]

      Parts sourcing for FHF 180 movement

      All watches are repairable a few oven duff tools knowledge skills. But I was just agreeing that it be easier to get a movement.

      About repair watch's jewel.

      By jhoho202 · Posted

      First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?

      Parts sourcing for FHF 180 movement

      I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank

      Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.
