This is a vintage men's Omega Constellation chronometer wrist watch. The case is well crafted in solid stainless steel with a gold tone enameled bezel. The dial has a gold tone with gold tone hour hands and markers with two sub dials. The timepiece functions with the original Swiss made quartz movement for accurate timekeeping. The piece fastens with a solid stainless steel and gold tone band for a secure worry free wear.

A chronometer is a very accurate (usually) mechanical watch with a high grade movement. The movement has been finely adjusted at the factory in several physical positions and temperature environments. A chronometer is almost always accredited and certified by either the watch manufacturer or by independent standards laboratories such as the Swiss based COSC (Contrôle Officiel Suisse des Chronomètres).
