The Tudor Black Bay is a large family of collections with several product lines. Among them, the Black Bay diver’s watch without any suffix is also known as the “original.” This year, for the first time, Black Bay (the original) has introduced a model with a black bezel insert and a black dial, a simple color combination reminiscent of Rolex’s famous “Calendarless Ghost.” In fact, the new monochrome Black Bay is not just a replacement for the Calendar; it has the potential to “catch up with Rolex” in some ways.

The new monochrome Black Bay, “Catching Up with Rolex,” is anti-magnetic and has been certified by the Swiss Federal Institute of Metrology (METAS) as a “Master Chronometer.” This is another product to receive this certification after the Black Bay ceramic, Black Bay “Little Red Shield,” and Black Bay 1958 GMT. Besides the daily accuracy requirement, the METAS certification also ensures that the watch can perform accurately even when exposed to a magnetic field of 15,000 gauss.

By comparison, all Rolex watches are currently required to be officially certified chronometers. This certification reduces the allowable daily error to ±2 seconds and includes a water resistance test. However, the official Rolex Superlative Chronometer certification does not mention anti-magnetic features. From this perspective, the new monochrome Black Bay, certified by METAS, is much more resistant to magnetic fields than Rolex.

The new monochrome Black Bay is powered by the TUDOR MT5602-U calibre; the “U” in the reference number indicates the version submitted for METAS certification. In addition to its excellent anti-magnetic properties, the MT5602-U calibre allows for a daily error of 0 to +5 seconds, which is stricter than the -4/+6 standard set by the COSC certification of Switzerland.

In terms of details, the new monochrome Black Bay now features the words “MASTER CHRONOMETER” on the dial to emphasize its importance. At the same time, TUDOR Sport’s iconic “snowflake hands” have been retained.
