Large Size Omega Constellation Extra Flat 151.0035 Yellow Gold

The Omega Constellation Chronometer Extra-Flat, reference 151.0035, circa 1972. This rare Constellation model features a large 18k solid gold rectangular case with “cut corners” and houses an ultra-slim Omega calibre 712 automatic movement. The dial is signed “OM Swiss Made OM” at 6 o’clock which was Omega’s designation mark used to indicate that the dial is made of solid gold (Or Massif). Overall the watch remains in excellent original condition and has been recently serviced by an independent watchmaker.
