Tudor Caliber MT5612

The Tudor caliber MT5612 is a time and date automatic movement tuned to run within chronometer spec and certified by COSC. This movement was originally introduced in 2015 (the photo above was captured by Caliber Corner at Baselworld 2015). It is considered to be an in-house movement, although more accurately Kenissi is the manufacturer, which is why Tudor refers to it as a manufacture movement. The MT5612 is equipped with a bidirectional rotor system and variable inertia balance, micro-adjustment by screw. This caliber also features a non-magnetic silicon balance spring. There is a similar Tudor caliber MT5602 (found in the Heritage Black Bay), with one less jewel and no date complication. Both MT56 calibres are 28,800 vph and 70 hr power reserve. “The Pelagos is powered with the new TUDOR Manufacture Calibre MT5612, 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).” “The Pelagos is powered with the new TUDOR Manufacture Calibre MT5612, providing impressive autonomy.
