This Omega Constellation Pie Pan is one of the early models featuring the Bumper Mechanism. Its dial has naturally aged and acquired a beautiful patina. It runs smoothly and accurately. The case is made of solid gold, except for the winding crown, which measures 35mm. The winding crown is original Omega. The buckle and strap are not original. The length is 21 cm. It keeps good time. The Constellation emblem on the back cover has been added later. This is a collector's item that the buyer will greatly appreciate, as it is a rare model.
