I'm not sure this is the right thread to post a watch assessment
@browncow -you would probably get more responses if it had its own thread
my views:
Fonts looks good on dial -mismatching Ms, Chronometre, etc all good
The outer edge of the dial looks though it has been repainted -could have been some corrosion around the outer edge -and is now coming off
hands look tired -and lume looks very aged
SWISS MADE -no Ts but that whole subject confuses me -but definitely repainted (badly)
replacement (thicker) crown -but possibly correct for the era?
case is polished but not too bad -lugs have just lost their edge
medallion is slightly worn despite what the seller says -but not too bad
movement looks a bit 'bleached' in places and as though it has some corrosion spotting on lower plates (out of focus) -could be signs of historical water ingress and corrosion being cleaned -and explain the repainted outer edge of the dial
strap not period -but goes well with the watch
$1,600 -silly price -quite expensive even if it was perfect
hope that helps
