An Omega Constellation stainless steel chronometer grade calendar wristwatch dating to 1966, in great overall condition. The case and dial present very well and the freshly oiled and adjusted 24 jewel chronometer grade movement runs strongly and keeps time with the calendar function operating correctly. This timepiece is signed four times, on the case, dial, crown and movement.
The vintage Constellation was Omega's top of the range waterproof chronometer and today it remains one of the most ionic, sought after and collectible of all vintage watches. It is a high end model, produced to compete with other prestige watches made by its main competitors. A chronometer, as opposed to a chronograph (a stop watch), is a timepiece that has passed a series of stringent tests carried out by the world’s major observatories to demonstrate very accurate time keeping (hence the observatory emblem on the rear cover).
Dial: in great condition, with a satin silver finish and hours marked by applied silver coloured batons. The dial is signed "Omega Automatic Chronometer Officially Certified Constellation Swiss Made ". It also bears the Omega emblem and Constellation Star. The hands are in good shape and the crystal is clean and clear.
Case: stainless steel, in good condition, measuring approximately 35 mm across, excluding the signed crown and 41 mm from lug to lug. The back of the case displays the observatory emblem in the centre with all eight stars visible. Looking inside the rear cover it is signed "Omega". The case shows the expected signs of use over the years but no signs of abuse, dents or scratches of any significance that I could see to point out to you other than some tool marks on the back of the case which could be polished out by a jeweller if desired.
Movement: cal. 561 Omega signed fully automatic chronometer grade movement with 24 jewels and adjustment to five positions and temperature for chronometer accuracy. Freshly oiled and adjusted by a master watchmaker, it is running well and keeping time. The serial number dates the watch to 1966.
Strap: lightly used generic brown leather strap which to the watch, measures approximately 217 mm from buckle tip to last hole.
