Tudor’s Black Bay Chrono “Carbon 25”

On May 3, 2025, Tudor released their third racing-themed two-register carbon fiber composite chronograph: the Black Bay Chrono “Carbon 25.” While Tudor’s other carbon chronographs were inspired by a yacht racing team and a cycling team, this watch is a nod to the Visa Cash App Racing Bulls Formula One Team. This time, even the dial is carbon fiber. Let’s dive into all the details of the Tudor Black Bay Chrono Carbon 25.

Tudor Black Bay Chrono Carbon 25 Price and Availability

The Tudor Black Bay Chrono Carbon 25 is limited to 2,025 pieces and debuts with a list price of $7,575. That price tag makes it the most expensive non-gold Tudor ever. Only the 18k Black Bay 58 and some two-tone watches (which Tudor calls “Steel+Gold”) cost more.

Why is This So Much More Expensive Than the Other Carbon Tudor Chronos?

It does seem odd that the Carbon 25 is priced almost two grand higher than the carbon composite Pelagos FXD models. Both the Pelagos FXD Chrono Cycling Edition and Pelagos FXD Alinghi Red Bull Racing Chronograph cost $5,600, and they have the same now-familiar Breitling B01-based MT5813 movement.

But there are a few justifiable reasons for the Carbon 25 being priced higher than the carbon Pelagos FXD Chronos:

• Titanium caseback (instead of steel)
• Carbon fiber endlinks (the Pelagos FXD has no endlinks)
• Carbon fiber dial
• Carbon fiber bezel (instead of titanium with a carbon composite insert)

Notable Details

The Tudor Black Bay Chrono Carbon 25, at 42mm wide and 14.3 thick, is 0.1mm thinner and 1mm wider than any other Black Bay Chrono. The flush endlink pieces, a first for the Black Bay Chrono in any material, are noteworthy.

Also, unlike previous carbon composite Tudor watches, which are a monochromatic flat black, the Carbon 25 has a marbled/textured look. It looks like forged carbon, though Tudor doesn’t use that term.

The star of the show, aside from possibly the case itself, is definitely the “Racing White” dial. The carbon fiber subdials immediately stand out, and in fact the entire dial–which is slightly domed–is carbon fiber. The subdials are simply left unpainted. The alternating orientation of the quarter-minute hash marks is a style that became popular in the 1970s and can still be seen on watches like the Omega Speedmaster Racing.

The black date wheel was a nice choice, and the tire motif on the hybrid rubber-leather strap ties in the racing theme. Let’s cover all the specs:

Final Thoughts

The Tudor resale market can be difficult to predict, but I expect this watch to get a good amount of attention. The VCARB F1 tie-in will probably get more hype than Tudor’s previous more obscure racing partnerships, though I’m still not sure if this will dethrone the blue-dial ceramic Black Bay as the hardest-to-get Tudor in 2025.

It’s definitely a cool watch, but Tudor typically has their most success in the $3,500-$6,000 ballpark, so it will be interesting to see how this sells. Along with the Tudor Black Bay Flamingo Blue, the Carbon 25 is likely to be one of the most popular 2025 Tudor releases.
