Is this a Franken bumper, and which Omega bumpers might be chronometers?

Spruce · Dec 27, 2020

No, I’m not bidding but I was curious about the movement/dial.

Advertised as a ‘refinished' dial, the poorly refinished dial describes the watch as a 'chronometre' whilst the 354 movement is marked ‘unadjusted'.

I assumed that this 354 wasn’t a 'chronometre' but wondered if a 354 was ever calibrated as a chronometre and, if not, which of the various bumper movements might ever achieve chronometer status

cal. 352, 354 (some), centre-second
333, 343, sub-second

And the chronometers would say Adjusted.

well at least the strap is the right width for the case.

I have a Seamaster Calendar powered with cal.353 and it is non-chronometer. The watch you've posted has a poorly refinished dial, seconds hand is goldtoned but it's color differs from the hour and minute hand (from the pics), also if this is a 14k or 18k gold model it should have hallmarks on the case or inside the caseback - which I don't see here.

Hi,

It is an American made 14k gold filled case.

Cheers,
