Thanks. Just a nice watch and a crummy photographer, I hope. I think it's just a shadow where there's a space in the shark-tooth marker and a triangular cutout in the chapter ring or, whatever that minute ring is called. But now I'll have to check when I get home.
Longines with a cal 12.68 Z movement. Very large - being from the fifties - at 37 mm. In good condition and it can not have been used much. The small dark marks above the Longines-text are in the crystal.
Careful what you wish for - you might just get it.... along with a kazillion dollar divorce. Guess there is now!
