Tudor Heritage Black Bay Black Chronograph 79350-0002

Tudor presented the 79350 in 2017. The MT5813 is a Breitling movement, developed from the B01 chronograph, which Tudor fits with its own adjustable-mass balance and a silicon hairspring; SJX gives it a three-day power reserve. A 45-minute counter sits at 3 o'clock and running seconds at 9, the crown and pushers screw down, and the dial carries a 200 m depth rating.

Set beside a three-hand Black Bay such as the 79230N-0002, it keeps the 41 mm steel case, black dial and 22 mm strap width; the fixed tachymeter in place of the rotating dive bezel is what changes. The 79350-0003 and 79350-0004 are the same chronograph delivered on a fabric strap and a steel bracelet.
