The level of detail here highlights Tudor’s increasing familiarity with working with the strong, ultra-lightweight material. The brand released its first-ever carbon fiber watch, which was also the first for its parent company, Rolex, back in 2023 with the launch of the 43mm Tudor Pelagos FXD.

Besides the material change, Tudor made additional changes to the case to distinguish the F1 collaboration from its core Black Bay Chrono references.

At 42mm wide and 13.3mm thick, the Black Bay “Carbon 25” is a mm wider and also slightly thinner than the typical stainless steel Black Bay Chrono.

At 42mm wide and 13.3mm thick, it’s a mm wider and also slightly thinner than the typical stainless steel cased version.

It feels natural to presume that the Tudor Black Bay Chrono “Carbon 25” is lighter than its stainless steel cousins, but Tudor’s press materials don’t include an official weight.

Internally, the watch is powered by the same MT5813 chrono movement used in the rest of the Black Bay Chrono family.
