Frequently asked questions

What is the lug width of the Tudor Pelagos 25707KN-0001?

The lug width of the Tudor Pelagos 25707KN-0001 is precisely 22 millimetres. It is measured between the two metal lugs on the case where the strap attaches horizontally. This measurement must not be confused with the overall width of the strap itself.

What is the best strap for the Tudor Pelagos 25707KN-0001?

The optimal strap choice depends on intended use. For diving and marine environments, a premium NATO strap in regenerated fabric (Navy Blue or Olive Green) guarantees maximum durability and rapid drying. For formal contexts, an alligator strap with vegetable tanning emphasises the elegance of the titanium case. For professional diving operations, an FKM rubber strap with integrated keepers is the best solution.

How do I change the strap on my Tudor Pelagos 25707KN-0001?

The Tudor Pelagos is fitted with standard spring bar lugs. Using a spring bar tool, apply gentle pressure to one of the metal pins to release the bar, remove the original strap, and insert the new one, ensuring the pins remain firmly seated. The process takes 2-3 minutes per lug. If inexperienced, consult a professional watchmaker.

Which aftermarket strap is compatible with the Tudor Pelagos 25707KN-0001?

Any strap with a 22-millimetre lug width is compatible. Milanostraps offers straps in alligator, anilina calf, regenerated NATO fabric, and rubber, all verified for precision tolerances. Avoid unknown brands, as imprecise tolerances may cause unwanted case movement.

How long does a leather strap last on the Tudor Pelagos 25707KN-0001?

Lifespan varies by material and maintenance. An alligator strap with vegetable tanning lasts 8-12 years with regular care; anilina calf 5-7 years if protected from excessive moisture; regenerated NATO fabric 15+ years without deterioration. If wearing the Pelagos underwater, always choose rubber or NATO, as wet leather degrades rapidly.
