Came across this PuristSPro thread from seven years ago recently while researching bumper chronometers: http://www.watchprosite.com/omega/seamaster-chronometre-restoration/677.754598.4992923/0/ I vaguely remembered it, and not just because I was a participant. MSN, Erich, and Hoi were also there. Well, I found this yesterday while scanning thru eBay: https://www.google.com/url?sa=t&rct...202219985768&usg=AOvVaw2bfTX10MIvJGohK2drRJdB I realize it's problematic, not least because of the low movement production number, but I have to wonder if maybe there's some credence to the notion of legit 354 rg's with three examples in hand now. [watch and photo credit: Hoi / 2011] Has anyone else come across one and dismissed it as a franken? Intrigued, Art
Art, IMO these are watches with swapped balance cocks which is a work of minutes - I don´t tink that there are any authentic cal. 354 with RG regulator best erich
Hi Art, I agree with Erich. Even in Omega's own "Nomenclature des Calibres" document no mention is made of an RG in a 354, and 352 was the designated RG calibre. I think maybe some watchmakers who live on the dark side could be encouraged to try this combination on because of the general infatuation of the Omega collecting community for anything RG Cheers Desmond
I think this is a very early cal. 352 movement with a swapped bridge: Note the serial number at 11.5M and the unusual font on the rotor. It's fairly priced for a working parts movement. gatorcpa
The ratchet wheel also looks like the RG version too on that movement so not just a RG bridge change, also the extra writing on the rotor is usually found on chronometer watches. I'm not really up on these movements so just an observation that will probably be shot down by those who really know what they are talking about.
Many cal. 354 chronometres with swan-neck regulators also had the extra writing on the rotor. Bang bang.
Not that far off the 14311 Chronometres of 1950+/- , well known to have early 352 RG's. Playing devils advocate, raises the possibilities of early 354's having over lap in parts? Might be better to have questionable movements disassembled and examined in the totality of their parts.
That was the consensus seven years ago as well, Desmond, even considering Hoi's identical movement within that thread on PuristS Omega forum. It did strike as more than slightly odd, though, that another would pop up with exactly the same architecture. One's a fluke, two's a conspiracy, but now with three, I'm not entirely confident anymore in the consensus judgement. Movement production numbers are widely scattered between them, which supports the notion that these examples are put-togethers. Still, I'm intrigued by this anomaly. Thank you all for your replies; I was away from home and unable to respond until just now. Art
