oldhippy Posted January 19, 2017 Share Posted January 19, 2017 Have you looked under the balance for the I D, my sight is not that good but I think I can see something under the balance. Or take the movement out, remove hands, dial, if nothing there take a photo of the dial side and post, many I D's can be recognized by the setting leaver work.

clockboy Posted January 20, 2017 Share Posted January 20, 2017 I think it is a FEF 6664. I say think because these style of movements look very similar to each other. To be certain you need to take measurements of the movement & also take what measurement if you can of the old balance staff. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?00&ranfft&a&2uswk&FEF_6664 to do your own research use this http://www.ranfft.de/cgi-bin/bidfun-2uswk.cgi?1&ranfft 1 Link to comment Share on other sites More sharing options...
Danh Posted January 20, 2017 Author Share Posted January 20, 2017 Thank you very much for your help i promise I did a lot of looking before I posted, but then went "movement blind" in the hope that someone would say "accurist used to use XYZ company" thank you again for your time Link to comment Share on other sites More sharing options...
oldhippy Posted January 20, 2017 Share Posted January 20, 2017 Thanks clockboy it sure looks like that's the one. Link to comment Share on other sites More sharing options...
clockboy Posted January 20, 2017 Share Posted January 20, 2017 OK getting the balance is the challenge. If the staff is the same as cal. 6600 or 430 then the staff can be purchased from the link below.. I might have one in my own stock.!!!!! My "bestfit" book does not show the 6664. So I suggest use the measurements shown @ the balancestaffs site for the 430 to see if it is the one required. http://www.balancestaffs.com/fef.php or http://www.ebay.co.uk/itm/3-piece-vintage-FEF-6600-Swiss-made-Balance-Staff-For-Watchmaker-265-/262805841601?hash=item3d3072e6c1:g:~pgAAOSwaB5XjdWG Link to comment Share on other sites More sharing options...

Marc Posted January 20, 2017 Share Posted January 20, 2017 I would certainly say that it was part of the same family of movements as the 6664 but there are a number of differences. The 6664 has a push pin stem release and an adjustable stud carrier. The OP's watch has a screw stem release, a fixed stud carrier, and a completely different set lever bridge/spring. It also has a cut away around the outer edge of the train wheel bridge, although this may simply be cosmetic. I'm not saying that it definitely isn't a 6664 as it is not uncommon for there to be slight variations within a particular calibre, however, this level of deviation is usually accompanied by a change in designation. Of course it may make no difference at all in this case as it could well be that the same balance staff is used across the whole movement family, but then again if there are variations in (for instance) beat rate within the movement family, this may also mean variations in balance design and potentially different staffs. It goes without saying that whatever it turns out to be it needs a non-shock protected staff and not the Incabloc illustrated on Ranfft. 1 Link to comment Share on other sites More sharing options...
clockboy Posted January 20, 2017 Share Posted January 20, 2017 Good useful info Marc. The only way to be really sure is measure the old balance & see if the same measurements apply to the 6600/430. 1 Link to comment Share on other sites More sharing options...

oldhippy Posted January 20, 2017 Share Posted January 20, 2017 Depends on your experience if you haven't replaced a b/s before you might think of obtaining a balance complete. 1 Link to comment Share on other sites More sharing options...
Danh Posted January 20, 2017 Author Share Posted January 20, 2017 That's a good point, it all depends on tooling costs i need to replace one at some point - so that point could be now Link to comment Share on other sites More sharing options...

Danh Posted January 20, 2017 Author Share Posted January 20, 2017 Thanks Kaz after looking at the tools I don't have to change the balance staff, I may replace the movement with a suitable ETA really helpful thanks Link to comment Share on other sites More sharing options...
oldhippy Posted January 20, 2017 Share Posted January 20, 2017 BUSAKAZ, I know your trying to help, but your movement is nothing like the Accurist, apart from size and shape. Just look at the difference in the plates and wind up mechanism, do you see how different they are. Link to comment Share on other sites More sharing options...

Oldhippy I can obviously see it is different but if it got him out of trouble he could of had the movement for free. Link to comment Share on other sites More sharing options...
