In Context

At 36 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. At 10.2 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 200 m puts it in dive-watch territory, well past anything daily wear will ask of it.

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.

A7438911.BD82 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case.

The B74 is Breitling's SuperQuartz three-hander with date for the larger cases, built on the ETA Thermoline 955.652. It powers 40 watches in this library, 32 of them Colts. SuperQuartz is thermocompensated quartz: a thermistor measures the movement's temperature and the oscillator's rate is corrected digitally, which holds it to a few seconds a year and earns COSC chronometer certification. The B74 has hours, minutes, seconds and a date, 7 jewels and a 25.6 mm diameter, and it exists so the Colt 44 and the Colt Skyracer could carry a Breitling movement at a price below the automatics. In the library it sits under 32 [Colt](/brands/breitling/colt) references, the Colt 36, Colt 44 and the Breitlight-cased Colt Skyracer 45 of 2017, and 8 [Galactic 36](/brands/breitling/galactic) quartz references. The 36 mm case accounts for 19 references, the 44 mm for 12, the 41.1 mm for 6 and the 45 mm Skyracer for 3. The [Caliber 77](/calibers/breitling-caliber-77) is the equivalent SuperQuartz for the 33 mm Colt, the [B71](/calibers/breitling-caliber-b71) the Galactic's, and the [Caliber 17](/calibers/breitling-caliber-17) the automatic the Colt offered beside it.

39 other watches in the library run the Breitling Caliber B74.
