I cannot find this watch face anywhere - I did a reverse image search and got close, but not. I'm interested in selling it but would like to know the approximate value. Thanks!
All you need is in the last photo you posted: model reference number is on the case back (four digits), caliber number is under the Omega sign (three digits). Search via this encoding, in gold..
Most references came with many dial variations, so you won't always find a match online. The reference number is 2369, and it's 14k gold. That's what you need to know for valuation, in addition to the condition obviously.
While we have the same numerals, raised indices, and hands, the comparison is inexact, because mine is 18k RG, the case is French, and the movement is cal 360, but I (well, obviously) agree that the dial is an attractive one. Bought too long ago to remember its price, but kept for its continuing value.
