Hi ro63,I see that Brietling,Huer and many others used this movement, the only one I've seen that was anything like it was a Avia Marineo,there does not appear to have been anything on the dial,so I don't know if they were sold new like this ,and if so why,I imagine it was a fairly expensive in its day,so you would think the maker would want their name on it.

Dugena used the 7733 in their chronos - though they changed the calibre number to 4002. A bit like Poljot copying it and calling a 3133.

Is there a calibre number underneath the balance wheel? The Dugena I have shows "7733" underneath the balance and, if I recall, the Russian clone has "3133" engraved on one of the bridges. As for the watch being unsigned, well, I suppose any maker could grab a movement and add hands, dial and case. Why - I've even done it myself!

 

Other than that, I don't know much more.

Hi Will, under the dial is the Valjoux stamp and 7733,I have seen unsigned watches on vacheron,s site and they are all factory samples,so I suppose it could be one of these,?

That's certainly a possibility. My guess is that a small watchmaker has bought some 7733 movements, cased them up and sold them. There are any number of unsigned makers/sellers out there that have done that over the years.

 

Whatever - enjoy the movement!

I think that watches were supplied sterile so retailers could put the own name/logo on if required. some small retailers probably didn't want the additional cost so left them as was. I have a 7734 with the name Jean Decret on the dial but have been unable to find anything on the brand at all!

If i remember correctly . the 3133 wasn't a direct copy, they added more jewels to the movement as well.. and the parts aren't interchangeable (well the parts i wanted unfortunately!)

7733 & 7734 have been nice movements to work with. think the difference is the 7734 has the date..

      Parts sourcing for FHF 180 movement

      By JohnR725 · Posted

      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

      By praezis · Posted

      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.
