Omega Has Officially Certified A 2-Hand Watch As A Master Chronometer

Omega’s new Constellation Observatory watches are the first two-hand models to earn Master Chronometer status using a novel acoustic testing method developed by its in-house lab.

  • Omega unveiled its Constellation Observatory Collection today, marking the first two-hand hour and minute watches to achieve Master Chronometer certification. President and CEO Raynald Aeschlimann said "Until now, precision certification has required a seconds hand," but a new acoustic testing methodology made this requirement obsolete.
  • Traditional COSC certification used photographic measurements over 15 days with accuracy standards of –4 to +6 seconds per day and only tested the movement, not the full watch. Both COSC and METAS testing previously required a seconds hand to verify accuracy.
  • The nine 39.4 mm watches underwent 25 days of acoustic testing at Omega's Laboratoire de Précision, recording every sound to detect irregularities. Calibre 8915 and Calibre 8914 movements, each mounted on a skeletonized rotor base, power the collection.
  • Actor Delroy Lindo wore the Moonshine Gold iteration, priced at $59,000, on the Academy Awards red carpet this year, previewing the collection before its Friday launch. The nine models retail from $10,900 to $59,100 and debut at Omega boutiques Friday.
  • The collection's design draws from Omega's more than 70 years of Constellation heritage, combining the two-hand dial from the 1948 Centenary with the pie-pan dial and medallion caseback from 1952. Observers may spot these timepieces at upcoming star-studded events next year, including potentially the Met Gala.
