Chronomat Automatic 36 Stainless Steel / MOP / Rouleaux

The Breitling Chronomat Automatic 36 A10320101A1A1 is part of the 2026 Chronomat redesign and presents the collection’s smaller automatic format in stainless steel. This reference has a 36mm case, a white mother-of-pearl dial with lab-grown diamond hour markers, and a stainless steel Rouleaux bracelet. The case measures 9.68mm thick, reduced from the previous 10.01mm profile used for the earlier Chronomat Automatic 36. The stainless steel case is water resistant to 100 meters and uses a non-screw-locked crown with two gaskets. The fixed bezel has indexes and rider tabs, retaining the Chronomat’s recognizable bezel language in a smaller automatic case. The dial uses natural mother-of-pearl, with lab-grown diamond markers, central hours, minutes and seconds, and a date aperture at 6 o’clock. Inside the watch is Caliber 10, a COSC-certified self-winding automatic movement based on the Sellita architecture. It runs at 28,800 vibrations per hour, uses 25 jewels, and provides an approximate power reserve of 42 hours. This reference is fitted to a stainless steel Rouleaux bracelet with a butterfly clasp and micro-adjustment on both sides of the clasp.
