The Pelagos is powered with the new Manufacture TUDOR MT5612 movement, providing impressive autonomy. Its power reserve of approximately 70 hours means 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. In addition to the hour, minute and central second functions, it provides an instant date display visible through an aperture positioned at 3 o’clock. Beating to a frequency of 28,800 beats/hour or 4Hz, this movement is regulated by a variable inertia oscillator with silicon balance spring, held in place by a traversing bridge fixed at both sides to improve resistance to shocks and vibrations. Its self-winding system is bidirectional. The movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
