Hi all,
Whilst having fun poking around this forum and the internet, I came across this Genève ellipse. The strange thing is that I could not find any matching model, neither here, on the internet nor in the Omega vintage database. Anyone here any idea as to series, date etc?

The Genève "Elipse" (Models 511.0416, 511.0417) were only realised for a short time, 1973 to 1976.

There are a couple of references in AJTT.

Strange but somehow appealing (to me that is)

Seeing this (thank you btw) makes me thing the gold plate is almost fully polished away, don’t you think?

Correct.
Inside the caseback of your watch you can see the words

LUNETTE and PLAQUE OR L 20 MICRONS, which translates to 20 Micron Gold Plate on the glass bezel.

FOND ACIER INOXYDABLE means stainless steel back.

Thanks guys, but is there anyone on the forum with a decent version on the OF? This series looks quite different from what I read that dor members have, considering the “oddness”

Plenty of 'oddness' on this forum if you look for it [and lots of smiles].

What I miss though is the movement number. Is that polished away or just not printed on the movement?

I'd say the reason is that the caliber 625 is a manual caliber using many parts of the automatic caliber 670, so it doesn't have the rotor or the upper bridge etc where the caliber marking is.



These were desperate times for Omega who, like many other manufacturers, was being impacted by the quartz crisis and as a result, some of their products did not meet the standards we see today.

Just being fussy, but "PLAQUÉ OR L" is short for "PLAQUÉ OR LAMINE," which means "gold-plated laminate."

IIRC the 625 was a cheapened evolution of the 620.

Incidentally there should be a sequel to AJTT soon for anyone that doesn’t have one, not sure on the ETA but it will be the gospel according to Petros, and should remedy many mistakes in the original and likely expand further on it.

I am willing to bet that these came in stainless steel as well as gold plate and just shared case backs. Look at the crown - it is the exact same as the gold plated one, but in steel/chrome plated finish.

I have an absolutely gorgeous DeVille (also a cal. 625) from the same era that is also in SS and has a "PLAQUE OR L 20 MICRONS" inscription in the back. No signs of work being done and came on a correct strap too. When googling the reference, I found other in steel, none seemed abused.
