Omega Seamaster 600 shoud I buy?

Crown might be incorrect, although no clear shot of it. Movement needs a service, add that to price.

S.H.

I also can't see if the crystal is original, and if the case is still sharp. Price is OKish considering what may have to be done, but be careful of the pictures. They may not give you a good impression of the dial, it has suffered a little from moisture (dark green lume, a bit of rust on the case clamps and the stem).

Wrong crown, looks like a ( wrong ) gold coloured crystal retaining ring, blackened lume, dial damage/repair at the 58 minute mark, probably needing a service....

This looks to me like a watch which at €450 would lead to a lot of buyer's remorse down the line.
