Rare vintage Omega Constellation Chronometer F300 watch purchased in Switzerland in 1974. Watch is keeping accurate time. Excellent vintage condition. 35 mm stainless steel case and integral solid lock band. Band approx 10 inch diameter, but clasp can be adjusted slightly to provide extra room. No additional links. Shows almost no sign of wear, there are some very light, barely visible scratches on the face which can only be seen in certain light, shown in the video posted. Battery replaced/watch serviced 7/15/25 and is working perfectly. Really lovely collectible timepiece
