Constellation Quartz 25.5 '95 Stainless Steel / Diamond / MOP

In Context

At 25.5 mm this is jewellery scale — a watch sized to be worn as an ornament rather than read across a room. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

It is quartz, so it will hold time far more closely than any mechanical watch here, and asks for a battery every few years rather than a service.

1476.71.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a stainless steel case.

The 1456 is Omega's two-hand quartz movement for the smallest cases, with hours and minutes and no seconds hand. It powers 94 watches in this library, all 22 mm to 25.5 mm. It is 15.15 mm across with 6 jewels, rhodium-plated with circular graining and gilded engraving, and its stepper motor advances three times a minute rather than once a second, which is what a two-hand movement needs. Rate is adjusted by inhibition, the standard method of trimming a quartz oscillator, and the battery lasts about three and a half years. Leaving out the seconds hand makes the movement smaller and the dial cleaner, which is why it sits in the diamond-set and mother-of-pearl models. In the library it sits under 64 [Constellation](/brands/omega/constellation) references, the Constellation Quartz 22.5 in steel and two-tone, and 30 [De Ville Prestige](/brands/omega/de-ville) Quartz 22 references. The 22.5 mm case accounts for 37 references, the 22 mm for 29 and the 25.5 mm for 27. The [1376](/calibers/omega-1376) is the equivalent two-hand quartz in the 24 mm and 27 mm cases, and the [1532](/calibers/omega-1532) the three-hand quartz with date in the 33 mm to 35 mm De Ville and Constellation.

93 other watches in the library run the Omega 1456.
