Introduced at BaselWorld 2016, the Heritage Black Bay Black is updated with Tudor's in-house movement and a riveted bracelet. An additional fabric strap is included in the package.
Movement
Beating to a frequency of 28,800 beats/hour or 4Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring, held in place by a traversing bridge - a guarantee of its robustness. The movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
