Tudor · Family: Pelagos
The Tudor Pelagos 25600TN is Tudor's dedicated titanium professional dive watch, launched in 2012 with 500m water resistance, a helium escape valve, and its signature self-adjusting bracelet clasp. The same reference code carried through a later, imprecisely dated switch from an initial modified-ETA-based caliber to Tudor's own in-house movement. Cazador has no verified price observations. Its differential: meaningfully lighter on the wrist than the steel Black Bay.

Tudor introduced the Pelagos in 2012 as the most technically oriented dive watch in its catalog — a tool-focused cousin within the same design family as the Black Bay, but executed in titanium rather than steel. The choice of titanium wasn't purely aesthetic: it meaningfully reduces wrist weight compared to a steel case of equivalent dimensions, a relevant factor for a watch meant to be worn through extended dives.
The 42mm case incorporates a helium escape valve, a component that controllably releases helium that has accumulated inside the watch during deep saturation dives, preventing overpressure from popping the crystal as the decompression chamber depressurizes. It's a feature found on professional dive watches oriented toward saturation diving, rather than typical recreational diving.
A distinctive feature of the titanium bracelet is its self-adjusting clasp, patented by Tudor, which automatically compensates for slight wrist swelling caused by pressure or temperature, without the wearer having to manually adjust the clasp.
At some point after its 2012 launch — a date we do not pin down precisely here — Tudor replaced the original modified-ETA-based caliber with its own in-house MT5612, chronometer-certified and with a longer power reserve, without changing the 25600TN reference code: two movement generations under the same commercial name.
In 2024, Tudor updated the Pelagos line with a redesigned, lighter case and a new caliber; we do not precisely confirm in this fiche whether the 25600TN reference remains in current catalog after that redesign or has been superseded by a new reference under the 'M' prefix Tudor uses in its more recent catalog nomenclature.
Cazador has no verified PricePoint observations for this reference, so we cannot publish a reliable market range.
Yes. The Pelagos is made of titanium, both case and bracelet, which meaningfully reduces weight compared to the steel Black Bay.
It controllably releases helium that has built up inside the watch during deep saturation dives, preventing overpressure from popping the crystal during decompression.
Per the data consulted, yes: the original modified-ETA-based caliber was later replaced by Tudor's in-house MT5612, keeping the same 25600TN code. We do not pin down the exact date of the change.
It's a Tudor-patented system that automatically compensates for slight wrist swelling, without the wearer needing to manually adjust the clasp.
500 meters, well above the 300-meter recreational standard common on other dive watches from the brand.
We do not precisely confirm this in this fiche. Tudor updated the Pelagos line in 2024 with a lighter case and a new caliber; verify against the current catalog before assuming availability.
