Overview
The Tudor Pelagos ref. 25600TN is a 42 mm titanium dive watch powered by the manufacture Calibre MT5612, representing Tudor's commitment to producing serious tool watches with fully in-house movements. Its matte black dial and lightweight titanium case make it a functional yet refined instrument suited to both professional and recreational diving. The reference has remained in production since 2015, cementing its place as a cornerstone of the modern Pelagos line.
History
The Pelagos line was introduced in the early 2010s as Tudor's flagship dive watch, reviving the brand's long heritage of robust underwater instruments that stretches back to the mid-twentieth century. The 25600TN arrived as part of a significant evolution of the line, most notably introducing the in-house MT5612 movement — a milestone that signalled Tudor's broader push toward manufacture independence. Titanium had already distinguished the Pelagos from Tudor's steel offerings, and the 25600TN continued that identity while pairing the lightweight case with a movement developed and produced entirely within the Rolex group's manufacture infrastructure. The reference has attracted a loyal collector following drawn to its combination of genuine tool-watch credentials and in-house horological substance.
Notable points
- The 42 mm case is crafted from titanium, making it notably lighter on the wrist than comparable steel dive watches of similar proportions.
- Calibre MT5612 is a manufacture movement featuring a silicon balance spring, a variable-inertia balance wheel, and a power reserve of approximately 70 hours.
- The matte black dial reinforces the reference's tool-watch character, prioritising legibility over decoration.
- A self-adjusting clasp integrated into the titanium bracelet allows on-the-fly sizing over a wetsuit without tools.
- The MT5612 carries COSC chronometer certification, underlining its precision credentials within a purpose-built diver's case.
