The Breitling Chronomat B01 42 (ref. RB0134101B1S1) is an automatic diver watch, with a 42mm 18kt pink gold case, 15.1mm thick, powered by the Breitling B01 movement and a 70-hour power reserve. Water resistance is rated to 200m, under a sapphire crystal. Manufacturer MSRP is $24,600.
Owners widely praise the Breitling Chronomat B01 42 for its excellent finishing, refined Rouleaux bracelet, and the robust B01 movement. The dial finishing, particularly on copper and copper variants, is highlighted for its dynamic sunburst effect. Some owners consider it an "all-in-one watch" suitable for daily wear due to its ruggedness and chronograph complication. However, multiple sources note that the 42mm case wears larger than its stated size, with a long lug-to-lug distance making it feel closer to 44mm and potentially too large for smaller wrists. The polished bezel is also mentioned as a fingerprint magnet, and one owner reported a magnetized example running significantly fast before demagnetization. On balance, owners and reviewers appreciate the Breitling Chronomat B01 42 for its impressive build quality and distinctive design, despite its substantial wrist presence.
