Tudor Black Bay Chrono (79360N, 79350, 79310N) Buyer's Guide | Ultimate Watch

The Tudor Black Bay Chrono is the watch that answered a question collectors had been asking for years: what happens when Tudor stops sourcing chronograph movements from ETA and starts building its own architecture. Introduced at Baselworld in 2017 as reference 79350, the Black Bay Chrono put a 41mm steel case, a fixed tachymeter bezel, and the snowflake hour hand from the Black Bay diver onto a proper column-wheel chronograph. The engine underneath was the news: the Manufacture Calibre MT5813, a COSC-certified column-wheel, vertical-clutch chronograph built on the architecture of the Breitling B01, running 70 hours of reserve and rated to 200m. That combination, a real dive-watch water resistance number bolted to a serious chronograph movement, did not exist at this price anywhere else in Swiss watchmaking. We buy and sell these across the counter at 19 W 47th Street every week, and the Black Bay Chrono has become one of the most requested Tudor references we handle. It sits in the sweet spot: enough dial and movement pedigree to satisfy a collector, priced where a first-time buyer can actually pull the trigger.
