In Context
At 32 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 8 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. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.
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.
A77320171C1A1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue gloss dial with a stainless steel case.
Inside: Caliber Caliber 77
Explore this caliber →The Caliber 77 is a SuperQuartz movement for the smallest Breitling cases, built on the ETA Thermoline 956.652. It powers 122 watches in this library, most of them the 33 mm Colt. SuperQuartz is Breitling's name for thermocompensated quartz: a thermistor reads the temperature of the movement and the rate is corrected digitally, which holds the movement to a few seconds a year and earns it COSC chronometer certification. The Caliber 77 is the three-hand-and-date version at 25.6 mm with 7 jewels, and it is what makes a Breitling possible at 32 mm and 33 mm without a mechanical movement the case could not hold. In the library it sits under 77 [Colt](/brands/breitling/colt) references, almost all the Colt 33 and Colt Lady, 23 [Chronomat 32](/brands/breitling/chronomat-32) references, 11 [Navitimers](/brands/breitling/navitimer) in the 32 mm and 35 mm ladies' sizes, 8 Super Chronomats and 3 Premiers. The 33 mm case accounts for 72 references and the 32 mm for 37. The [B71](/calibers/breitling-caliber-b71) is the equivalent movement in the Galactic, and the [B74](/calibers/breitling-caliber-b74) the larger SuperQuartz three-hander in the Colt 44.
121 other watches in the library run the Breitling Caliber 77.
