THE TUDOR MANUFACTURE CALIBRE
In 2015, TUDOR announced its first Manufacture Calibre in its history. A high-performance calibre of excellent precision and proven robustness, it offers a 70-hour power reserve meaning that its wearer can, for example, take off the watch on Friday evening and put it on again on Monday morning without having to wind it. 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. Furthermore, the movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
