Breitling · Automatic

B72

Part of Breitling's SuperQuartz family, built on ETA's Thermoline platform. A single 32 kHz crystal is corrected digitally against a thermistor reading, so the movement compensates for its own temperature drift rather than running at whatever rate the ambient conditions dictate. That is what takes it to about ten times standard quartz accuracy and qualifies it for COSC chronometer certification.
