Breitling Chronomat B31 40 Stainless Steel / Silver / Rouleaux Ref. AB3114101A1A1

The Breitling Chronomat B31 Automatic 40 AB3114101A1A1 is a stainless steel time-and-date model introduced with the 2026 Chronomat redesign. This reference has a 40mm case, a white dial, and a stainless steel Rouleaux bracelet. The case measures 10.99mm thick and uses the updated Chronomat construction with concealed lugs and a fully integrated case-and-bracelet profile. The case is water resistant to 200 meters and fitted with a sapphire crystal. The unidirectional ratcheted bezel has raised rider tabs, numerals, and minute indexes, keeping the Chronomat’s external timing-bezel layout in a simpler automatic format. The white dial has applied hour markers, central hours, minutes and seconds, Super-LumiNova on the hands and indexes, and a date aperture. Inside the watch is Caliber B31, Breitling’s COSC-certified manufacture automatic movement introduced in 2025. It runs at 28,800 vibrations per hour and provides an approximate power reserve of 78 hours. This reference is fitted to a stainless steel Rouleaux bracelet with a concealed butterfly clasp and Breitling’s patented micro-adjustment system.
