Omega from the 1920s, still in completely original condition. The case is shaped like a cushion ---> 'cushion - case'. The measurements are +/- 30 x 30 mm. (without the crown and strap attachments). The silver case is marked and numbered (7107504) on the inside. The silver grade is probably around 0.500. The Omega movement has 15 jewels and two adjustments. It has a 26.5 SOB calibre and is numbered 67, which dates this watch back to around 1927. The movement runs nicely for a 90 year old.. Has been cleaned and oiled. Brass crown and a beautiful convex glass without scratches. The case and lid have matching numbers and belong together. Porcelain dial is still very beautiful, only with a hairline crack in the middle. Blued steel hands. The brown lizard leather strap is worn (of old-fashioned quality) and still very good for use. IN SHORT: a rarely offered antique Omega, still in authentic condition, well running and worthy of collection, or it can just be worn (with some respect for its age). 3 MONTHS WARRANTY! Will be shipped registered. (no shipping between 14 and 21 March.)
