The Constellation range appeared at Omega in 1952. The movements are certified chronometers and the case backs are engraved with the image of the Geneva Observatory as well as eight stars.
You can follow the service of an Omega Constellation fitted with the same caliber in this blog article:
Dial: Patinated sunburst silver dial with dauphine hands
Case: Steel
Diameter: 35 mm
Movement: Omega 564 chronometer with automatic winding 24 jewels - quick date setting
Bracelet: Omega steel 19 mm for a wrist with a maximum circumference of 18 cm
Condition : Superb condition, this watch has never been polished. The acrylic crystal is original Omega. I cannot find any trace of this Omega steel bracelet, perhaps it belongs on another reference, but it suits our Constellation beautifully. Very good condition for its age. The movement has been completely serviced, this Omega runs perfectly.
