Hi, I have been looking for a Seamaster from the 1960, steel case and bauhaus style dial. I got these 2: Automatic cal 550, case ref 165.002. It seems in good condition, keeps time. Dial has a slight patina. Seamaster 600 ref 135.011. cal 601. Dial seems more damaged, although it has a better contrast (I had some doubts about the originality of the dial). I like the case slightly better and the crystal seems a bit more domed, the crown looks correct. Since they are very similar I will keep one and sell one. I like the dial and case of the Seamaster slightly better although there is more damage. The Automatic is automatic, I do not have a cal 550 and the dial seems better preserved. I can service one and sell the other, or service both and sell one serviced / cleaned. I wonder if that stain on near 5 o'clock on the Seamaster can be cleaned. I'd like to have some opinions / advice. I would be wearing it so I am not looking for watches in pristine condition. The lighting for the photos is pretty directional and harsh, the watches look better in daylight thanks stefano
