The history of this Omega Constellation
The Omega Constellation retains the silhouette established in 1982, when the brand unveiled the Constellation Manhattan, designed by Carol Didisheim, who had joined Omega two years earlier. This design features four ‘claws’ on the case middle – two at 3 o’clock and two at 9 o’clock – which frame the bezel and have remained the collection’s distinctive hallmark ever since. The first Manhattan models were quartz-powered, with automatic versions not appearing until 1984. This ladies’ Omega Constellation, reference 123.15.27.20.55.001, features these claws on a brushed steel case and is powered by a Co-Axial movement certified as a chronometer, visible through the case back. Diamonds are set wherever the design allows, on the bezel, between the claws and on the hour markers on the dial.
Case, calibre and strap of this Constellation
The brushed steel case measures 27 mm in diameter and 30.10 mm from lug to lug, with a water resistance of 100 metres. Its bezel is set with 32 diamonds, and each side also features a diamond set in a square bezel, between the claws. The white mother-of-pearl dial features a supernova sunburst pattern, 11 diamond hour-markers set in bezels, a date window at 3 o’clock and facetted hands. The domed sapphire crystal is treated with an anti-reflective coating on both sides. The sapphire caseback reveals the self-winding Calibre 8520, featuring a Co-Axial escapement, a Si14 silicon balance spring and 28 jewels. It beats at 25,200 vibrations per hour, offers a 50-hour power reserve and features an arabesque Côtes de Genève finish on its oscillating weight. The brushed steel bracelet, with horizontal bars, fastens with a double folding clasp stamped with the Omega logo.
Why this Omega watch
This model is no longer produced by Omega, and the second-hand market allows you to acquire it in its original configuration, including the mother-of-pearl dial and gem-set bezel. It combines, within a small case diameter, a chronometer-certified mechanical movement – with no battery to replace – and original Omega gem-setting on the bezel, lugs and dial. The Co-Axial escapement minimises friction between moving parts, reduces the need for lubrication and helps the movement maintain its accuracy over time. With a diameter of 27 mm and an integrated bracelet, it slips easily under a shirt cuff.
Contents and condition
The watch is supplied in a ‘The Swiss Collector’ box, along with its original invoice dated January 2012, issued by a jeweller in Lucerne. It shows minor scratches from normal wear on the case, bracelet and clasp, and all its diamonds are in place. As the case and bracelet are fully brushed, polishing can be carried out on request at the time of purchase to remove these marks and restore the steel to its original finish. The watch has been inspected by our experts prior to being put up for sale.
