Overview

The Tudor Black Bay Ceramic ref. 79210CNU represents a significant material milestone for the Black Bay line, housing the collection's familiar diver architecture within a 41 mm black ceramic case. Its monochromatic aesthetic — black case, black dial — gives the watch a distinctly contemporary character while retaining the vintage-inspired design cues that define the broader Black Bay family. The calibre MT5602-1U, certified to METAS Master Chronometer standards, anchors the reference firmly in the modern era of high-precision, antimagnetic movements.

History

Tudor introduced the Black Bay Ceramic in 2021, marking the first time the brand deployed a full ceramic case in the Black Bay line — a notable departure from the stainless steel and bronze executions that had defined the collection since its relaunch in the early 2010s. The reference built on Tudor's growing investment in in-house movement development, pairing the new case material with the MT5602-1U, a movement that meets the stringent METAS Master Chronometer certification. The Black Bay Ceramic quickly attracted attention from collectors drawn to its technical ambition and the visual coherence of its all-black presentation. It remains in active production, cementing its place as one of the more technically distinguished references in the current Black Bay catalogue.

Notable points

  • The 41 mm case is crafted entirely from black ceramic, making ref. 79210CNU the first full-ceramic execution in the Black Bay line.
  • The calibre MT5602-1U holds METAS Master Chronometer certification, guaranteeing a daily rate of 0 to +5 seconds and resistance to magnetic fields of at least 15,000 gauss.
  • A fully monochromatic design — black ceramic case, black dial, and matching black elements — distinguishes the reference visually from all other Black Bay variants.
  • Despite its contemporary material, the watch retains classic Black Bay design signatures: the domed crystal, the snowflake hand, and the characteristic "big crown" profile.
  • As a diver's watch, the reference maintains the water resistance and legibility standards expected of the Black Bay line's tool-watch heritage.
