Vintage Omega Constellation Chronometer Automatic 157.0001 - 35mm - 1968

Vintage Omega Constellation Chronometer from 1968 with a gray dial featuring a vertical brushed finish. The stainless steel case retains its complete original polish and appears unpolished. Inside is the ultra-thin automatic caliber 712, a thinner version to the caliber 500 series, giving the watch its slim profile. The movement was serviced in January 2026 and currently runs and functions perfectly. It is paired with a top-grain brown leather strap with a crocodile motif and light glossy finish, the only non-original component, as the rest of the watch remains entirely original and in exceptional condition.
