Breitling Chronomat Automatic 36 Stainless Steel - Diamond / Grey MOP / Rouleaux Ref. A10320591G1A1

The Breitling Chronomat Automatic 36 A10320591G1A1 is a stainless steel model from the 2026 Chronomat redesign. This reference has a 36mm case, a lab-grown diamond-set bezel, a grey 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 Chronomat Automatic 36 profile. The case is water resistant to 100 meters and uses a non-screw-locked crown with two gaskets. The fixed bezel retains the Chronomat rider-tab layout and is set with lab-grown diamonds. The dial is executed in natural mother-of-pearl and displays central hours, minutes and seconds, with 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.
