About Omega
Louis Brandt opened his workshop in La Chaux-de-Fonds in 1848; his sons moved the company to Biel in 1880, and it took its name from their 1894 caliber, the Omega, a movement built from interchangeable parts. The modern catalogue dates from four launches. The Seamaster of 1948 gave the brand its waterproof line, and the 1957 trilogy of Speedmaster, Seamaster 300 and Railmaster gave it its tool watches; the Constellation of 1952 is the dress chronometer, and the De Ville of the 1960s the plain dress watch. Those two are the largest collections here, 964 and 756 watches, ahead of the Aqua Terra at 579, the Seamaster Diver 300M at 274 and the Planet Ocean at 244.
The movement story is the reason the caliber list is so long. In 1999 Omega put George Daniels's co-axial escapement into an ETA base as the 2500, still the most common caliber here with 398 watches; the in-house 8500 of 2007 followed, then the 8800 and 8900 families certified by METAS as Master Chronometers from 2015. The Master Chronometer piece sets out the eight tests, including a 15,000 gauss magnetic field, and lists the seventeen calibers here that pass them. The quartz side is large too: the 1376 and 4061 are inside 599 watches between them, most of them Constellations and De Villes.
Omega makes more chronographs than any other brand here, 783 watches or 21 per cent. The Speedmaster Moonwatch, the hand-wound chronograph NASA qualified in 1965 and Apollo 11 wore in 1969, is the famous one, on the 3861 today; the chronograph piece explains how its cam architecture differs from the column wheel of the 9300 and 9900 families, and the Lemania 2310 piece traces the Moonwatch movement back to the same ébauche a Patek Philippe used.
The cases are more varied than the rivals'. Forty-five per cent are steel, 28 per cent gold or platinum and 14 per cent two-tone, with 88 ceramic cases and 84 titanium. The median case is 38 mm, with 41 mm and 42 mm the most common sizes and 27 mm and 34 mm close behind. Sixty-one per cent are rated to 100 m or more and 15 per cent to 300 m or more, the Ploprof and Planet Ocean at the deep end. Eight per cent are limited editions, half have a display back, and the rarity median is 4.
