Chronomat Automatic 36 Stainless Steel - Red Gold - Diamond / Brown / Rouleaux

The Breitling Chronomat Automatic 36 U10320591Q1U1 is a two-tone model from the 2026 Chronomat redesign. This reference has a 36mm stainless steel and 18k red-gold case, a brown dial with lab-grown diamond hour markers, and a stainless steel and 18k red-gold Rouleaux bracelet. The case measures 9.68mm thick and is water resistant to 100 meters. The fixed red-gold bezel is set with lab-grown diamonds and keeps the Chronomat’s rider-tab layout. The case uses a non-screw-locked crown with two gaskets. On the dial, the brown finish is combined with 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 two-tone Rouleaux bracelet with a butterfly clasp and micro-adjustment on both sides of the clasp.
