Breitling Chronomat B31 Automatic 40 (AB3114101)

Breitling Chronomat B31 Automatic 40 (AB3114101) owners widely praise its slim profile and comfortable wearability, with many appreciating the 40mm case size as a more manageable option than its larger siblings. The micro-adjust clasp receives specific commendation for its excellent functionality, and the see-through caseback is a welcomed addition by some. The B31 movement's architecture is noted as adaptable, and its rotor winding is described as nearly as good as an El Primero, with a power reserve of approximately 78 hours. However, some owners express a preference for older Chronomat bezel designs with screws, finding the newer smooth bezels less functional. A few also feel the case redesign detracts from the integrated aesthetic and find the $6000 price point too high for the offered features.
