I am developing The Watchmakers App ( https://thewatchmakersapp.com ) and currently started to update the app with early Omega movements from Omega GF 239 catalogue (1926).

When looking for differences between Cal. 17.4 T1, T2 and T3 I found out from this forum that those might be mentioned in another catalogue GF 494 (1936?). I assume I might find helpful info there about other movements too, as it's marketed as supplement to GF 239. So now I am trying to source GF 494 catalogue, if…

Just got this watch at local vintage watches meet. Looks like NOS, even has the Zenith tag attached with number from the caseback. The oils are so dry it doesn't even tick (balance staff is not broken). But looks like the dial has some tiny paint specs. What do you think about the watch and the dial?

Initially I thought the lume was just fallen of, but then I realised it was made like that on purpose (looks like factory lume to me). I found this interesting, decided to share. The star is also lumed.

I have the watch with this case. Movement number matches 1969, there is engraving by some previous owner on the case back with 1972 and from the factory 212D085. I wonder if 7-68 inside the case means July 1968? I looked into some dating threads but couldn't find the answer in 30 minutes so I thought I will ask here.

I spotted this watch last year, but wasn't sure if it's anything interesting, so asked @Hartmut Richter about it and by his answer I got an idea that it's not very common. So I managed to get this watch this weekend and thought I will share it here as well.
