Tudor caliber MT5633

The Tudor Manufacture Calibre MT5633 is a self-winding mechanical movement with 26 jewels, displaying central hours, minutes, and seconds, together with a day indication at 12 o’clock and a date at 3 o’clock. It is part of Tudor’s Manufacture calibre family and combines an automatic winding system with a bidirectional rotor and a power reserve of approximately 70 hours. The movement is regulated to a running tolerance of -2/+4 seconds per day on the fully assembled watch and includes a stop-seconds function for precise time setting. Its construction is centred on stability and robustness, with a variable inertia balance secured by a traversing bridge with two-point anchoring, alongside a non-magnetic silicon hairspring. The finishing includes an openworked tungsten monobloc rotor with satin-brushed and sand-blasted surfaces, while the bridges and mainplate combine sand-blasted, polished, and laser-decorated sections. The overall architecture reflects Tudor’s focus on durability, chronometric stability, and long running autonomy within its modern Manufacture movement platform.
