This is a classic Seamaster 600 vintage gold-plated Omega dress watch, serviced in 2026 and running excellently. It has a stunning Omega 611 manual-wind movement with a sweep second hand and date function. It is fitted with a new tan leather strap with quick release spring bars. It comes in a genuine Omega travel case. The watch would make an excellent birth-year gift, manufactured in 1966 (Serial number 24,049,984). The case has 40-micron gold plate in good condition. During servicing a new mainspring was fitted, as well as a new generic crystal and gold-plated crown. Original vintage dial, with some patina and marks.

This watch has a screw down case back embossed with the Seamaster logo. The case back has the style code 136.011 stamped internally. This watch has the excellent Omega 611 movement, with a semi-quick set date function (turn hands to just past midnight and then back to 9 pm, then back to midnight to change date).

I have not tested the watch for being waterproof, hence it must be assumed not to be. Please check photos for condition.
