The Black Bay Chrono was created to commemorate the 50th anniversary of the first chronograph model from Tudor. This is the updated 2021 [M79360N-0001 Black Bay Chrono].

The previous model had the tachymeter scale engraved directly on the stainless steel, but this new model has a black anodized insert for the bezel plate, which gives the tachymeter bezel a tighter look similar to that of the Rolex Daytona.

The movement is the manufacture caliber MT5813 with column wheel and vertical clutch. The MT5813 is certified by the Swiss Official Chronometer Testing Institute (COSC) and has a power reserve of approximately 70 hours.

The riveted bracelet, which nostalgically recalls the 50s and 60s in accordance with Tudor's traditional snowflake hands, is also very carefully crafted.
