About the Omega 1456

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 references, the Constellation Quartz 22.5 in steel and two-tone, and 30 De Ville Prestige 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 is the equivalent two-hand quartz in the 24 mm and 27 mm cases, and the 1532 the three-hand quartz with date in the 33 mm to 35 mm De Ville and Constellation.
