Seamaster Aqua Terra 150M Quartz 36.2 Yellow Gold / Black

In Context

At 36.2 mm it is classically proportioned: the size a dress watch was understood to be for most of the twentieth century, and small enough to sit under a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 150 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

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.

2318.30.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a yellow gold case. Introduced in 2002.

The 1538 is Omega's three-hand quartz movement with date for the Seamaster, and the movement inside the quartz Bond watch of GoldenEye. It powers 43 watches in this library. It oscillates at 32,768 Hz, the standard quartz frequency, with 6 jewels at 23.3 mm across and 2.45 mm high, and its battery lasts about three years. The 1995 film put a quartz Seamaster Professional 300M, the blue-dial 2541.80, on Pierce Brosnan's wrist, and it was this movement inside; the automatic 2531.80 with the [1120](/calibers/omega-1120) followed in the next film. In the library it sits under 29 [Seamaster Diver 300M](/brands/omega/seamaster-diver-300m) references, the quartz 41 mm and 36.25 mm mid-size, 8 Seamaster 120M references and 6 quartz [Aqua Terras](/brands/omega/aqua-terra). The 36.25 mm case accounts for 19 references and the 41 mm for 17. The [1424](/calibers/omega-1424) is the smaller quartz with date in the 28 mm Seamaster, and the [1532](/calibers/omega-1532) the equivalent in the De Ville and Constellation.

42 other watches in the library run the Omega 1538.
