This explains why brands like Seiko or Citizen recommend some regular wear to maintain the accuracy of their "standard" quartz calibers. Most quartz crystals are calibrated to perform at best around 28℃ (or around 82℉), which is the temperature inside the case when the watch is worn on a human wrist. Yet, its oscillations see some variability when its temperature changes. It is not so much that a vibrating quartz in a "standard movement" is not accurate: intrinsically it constitutes an excellent harmonic resonator, with a remarkably stable frequency. On the Skyracer, it has a matte finishing interestingly, Breitling did not apply for a patent, just a trademark, so one can assume that the formula or the composite itself was supplied by an external party who still holds the IP.Īs an independent thermal sensor, the thermistor holds a crucial place in improving the accuracy of a sophisticated quartz movement (often called HAQ or HEQ, for High Accuracy Quartz, or High End Quartz). Besides its impressive lightness, it's also antimagnetic and hypoallergenic. In a more tech-savvy parlance, it is an isotropic thermoplastic composite with (very likely) short carbon fibers as reinforcement to the matrix. This is the very first time that this advanced material has trickled down to Breitling's entry-level family, the Colt.ĭescribing it as a molded plastic polymer would be technically accurate, but slightly underwhelming since the term plastic is a pretty generic one. A smaller Avenger Hurricane was then unveiled, its diameter reduced to “only” 45mm (yes, modern Breitlings do tend to be on the bigger side). Breitling trademarked the Breitlight name back in October 2015, and initially introduced it the following year on a 50mm Avenger Hurricane, with a price tag fourfold over this Skyracer.
