Please show your vintage Constellations.
Would be great to see the variations in a new thread. I'll go first.
1961 Pie pan, Cal 561, Case Ref 14393, on a period 7912 Bracelet (stainless steel)
Looks like a dome dial which would indicate ref. 168.010. The 168.018 would have a flat dial and 19mm lug width. The good fit of the leather strap would also say your watch has a 18mm lug width.
Thank you very much for your input, I appreciate it, the dial is indeed dome. I was speculating that it might be a CD 168.0010, but did not know how to tell them apart.
Crowns are easily interchangeable, but you can't easily fit a dome dial into a flat dial watch.
What a lucky coincidence, thanks! I will have to fix that...at least to a certain degree, with a semi-recessed crown, as you you suggested. I assume that crown can be sourced new from Omega?
One last question: Omegas from this period do have the logo molded in the crystal, or else the crystal is not original?
Is it possible to source the right crystal from Omega or only from old stock?
