About This Reference

The M7941A1ACNU-0001 represents Tudor's most technically ambitious Black Bay to date — a full ceramic watch with a matching full ceramic bracelet. Working ceramic into a case is challenging enough; engineering an entire three-row bracelet from the material is a genuine feat of manufacturing that only a handful of brands have ever attempted, and Tudor's execution delivers on both durability and comfort. The matte black micro-blasted finish across the case and bracelet gives the watch a tactile quality that sets it apart from polished ceramic competitors, and the material's inherent scratch resistance and anti-magnetic properties complement the MT5602-U movement inside — a Kenissi-manufactured calibre carrying both COSC and METAS Master Chronometer certification for accuracy within 0 to +5 seconds per day and magnetic resistance exceeding 15,000 gauss. With 70 hours of power reserve, 200 metres of water resistance, and Tudor's signature Snowflake hands on a charcoal dial, this is a tool watch built from a material that refuses to show wear.
