Omega Constellation Cal 551 Auto Pie-Pan Watch

A cornerstone of mid-century Swiss precision, this Omega Constellation represents one of the brand's most celebrated chronometer lines, combining technical excellence with understated design. Produced during the golden era of Omega's chronometer development, this example is powered by the highly regarded Caliber 551-one of the finest automatic movements of its time.

The dial displays the classic Constellation aesthetic, featuring applied hour markers and the signature star above 6 o'clock, denoting Omega's chronometric achievements. Its surface shows honest aging and patina consistent with its vintage character, giving the watch a warm, authentic presence that collectors appreciate.

The stainless steel case retains its original form, complemented by the iconic Constellation observatory medallion on the caseback-symbolizing Omega's record-setting performance in international chronometry trials. Inside, the Cal. 551 automatic movement is visible, showcasing Omega's robust engineering and finishing from this era.

Accompanied by its original Omega box and papers, this example offers a complete presentation that is increasingly difficult to find, enhancing both its collectibility and long-term desirability.
