Here are some extra pictures. The link you sent is for a different movement which I believe has different feet. This watch is a cal 354 with the correct case back and serial numbers (in terms of range).
Re dial specifics, I’ve given some thought to this too. The photos from Omegamania and Phillips auctions are static. No videos of this the watch exist (other than a few seconds in the 2nd John Goldberger Hondinkee talking watches video). Secondly, it’s hard to say how or how differently these dials could have aged over the past 70 years, because there are so few around.
Re provenance, I believe im the third owner. The seller purchased it in 2006 from the original owner, who had it since the 50s.
