Overview
The Tudor Pelagos 25600TB is a 42 mm titanium professional diver's watch distinguished by its matte blue dial — a combination that has made it one of the most recognisable references in the modern Pelagos family. Introduced in 2015, it marked a significant moment for Tudor by pairing the brand's own manufacture calibre with the proven Pelagos platform. The result is a tool watch that balances serious dive credentials with the refinement expected of an in-house movement.
History
The Pelagos line was conceived as Tudor's flagship diver, drawing on the brand's long heritage of producing robust professional watches for demanding environments. When the 25600TB arrived in 2015, it represented a maturation of that lineage, replacing a third-party movement with the manufacture Cal. MT5612 and cementing Tudor's ambitions as a movement maker in its own right. The blue-dial variant quickly became the more sought-after expression of the reference, appreciated by collectors for the interplay between the matte blue surface and the lightweight titanium case. It has remained in continuous production, a testament to the enduring appeal of the configuration.
Notable points
- The 42 mm case is crafted entirely from titanium, making the watch notably light on the wrist despite its substantial proportions — a defining characteristic of the Pelagos platform.
- Cal. MT5612 is a Tudor manufacture movement featuring a silicon balance spring, a COSC-certified chronometric rating, and a power reserve of approximately 70 hours.
- The matte blue dial gives the 25600TB its popular identity within the Pelagos range, contrasting cleanly with the satin and polished surfaces of the titanium case and bracelet.
- Tudor supplies the watch with both a titanium bracelet and a rubber strap fitted with a T-fit rapid-adjustment clasp, allowing on-the-fly sizing over a wetsuit.
- The reference has been in continuous production since 2015, reflecting sustained collector and enthusiast demand for the blue-dial titanium configuration.
