The Breitling Super Chronomat Automatic 38 (ref. U17356531L1U1) is an automatic chronograph watch, with a 38mm stainless steel & 18k red gold case, 11.88mm thick, powered by the Breitling 17 (ETA 2824-2 base) movement and a 38-hour power reserve. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $15,850.
Owners find the Breitling Super Chronomat Automatic 38 on a rouleaux bracelet works well, though some note the case feels substantial and wish for bracelet micro-adjustment. One owner reported significant accuracy issues, with the watch running between +5 to +20 seconds per day or -30 seconds per day, and an inconsistent power reserve around 36 hours, requiring two service visits. Overall, owners are split on the 38mm sizing, with some finding it ideal and others preferring larger cases.
