The Constellation Observatory, the First Two-Hand Watch to Achieve Master Chronometer Certification, Fully Tested at the Laboratoire de Précision

A new acoustic testing method developed by the Laboratoire de Précision enables Master Chronometer certification of a two-hand watch for the first time.

Two years after the announcement of the Laboratoire de Précision, OMEGA introduces the Constellation Observatory Collection. Using an acoustic testing method combined with optical hand‑tracking developed by the Laboratoire de Précision and certified by METAS. The collection’s movements and watches undergo both Chronometer and then Master Chronometer testing without the need for a seconds hand. For the first time in watchmaking history, a two-hand hour and minute watch has achieved Master Chronometer certification.

Since 1952, the Constellation has represented OMEGA’s commitment to certified precision. The Constellation Observatory Collection marks the next step in this legacy with two new movements across nine references. The 39.4 mm timepieces unite decades of Constellation design heritage with modern precision testing and exclusive materials across the collection. 

Two new calibres feature across the collection, each built on a skeletonised rotor base with polished or shined bevels, rounded outer zone on the rotor, and an applied Constellation Observatory medallion. They are presented in three categories: Grand Luxe, Luxe, and Standard.
