I'm hereby selling an Omega Constellation. The watch is in good condition and runs accurately. The maintenance history of the watch is unknown. This is a mechanical/automatic watch. The automatic has a Omega calibre 551. The serial number starts with 18.xxx.xxx, dating this watch to 1961 (also see the lid). The case diameter is 34 mm (measured without the crown). The lug-to-lug size is 18 mm. The watch has an original signed crown. The dial was professionally redone once and has a small point of damage between the 4 and 5. This is not really noticeable though. The watch has a leather strap with a length of 21 cm (including watch). Both the strap and the buckle are no originals by Omega. The original box and papers are not included with the watch either. The watch will be shipped well-packaged and by registered (insured) post.
