Frequently asked questions
What is the lug width of the Tudor Pelagos 25807KN-0001?
The lug width of the Tudor Pelagos 25807KN-0001 is 22 millimetres. This dimension accommodates straps with robust cross-sectional profiles, essential for distributing load during professional diving operations. To verify compatibility, measure the linear distance between the suspension pin axes of the case using a digital calliper.
What is the best strap for the Tudor Pelagos 25807KN-0001?
The optimal strap depends on intended usage. For professional underwater operations, a cotton gabardine NATO maintains constructive minimalism and saltwater resistance. For urban and formal contexts, superior-quality alligator leather offers a natural grain structure that dialogues with the matte carbon bezel. Vegetable-tanned calf represents a versatile solution, developing an accelerated patina over time.
How do I change the strap on a Tudor Pelagos 25807KN-0001?
To change the strap, remove the suspension pins using a spring bar tool (a slender instrument specifically designed for this purpose). Position the tool beneath the pin, applying gentle upward pressure, then extract the pin from its seat. Repeat on the opposite side. Insert the new strap by aligning the lugs to the pin holes, then reinsert the pins with gradual pressure until they lock into place.
Can I fit an aftermarket strap to a Tudor Pelagos 25807KN-0001?
Yes, you may fit aftermarket straps provided the lug width corresponds precisely to 22 millimetres. Ensure the strap is constructed to elevated standards, featuring certified leathers and resistant double stitching. Italian artisanal straps offer guaranteed compatibility, personalised length adjustment and selection from premium leather materials.
How long does a leather strap last on a Tudor Pelagos 25807KN-0001?
A high-quality leather strap, subject to correct maintenance, lasts between 3 and 7 years. Longevity depends upon frequency of use, exposure to chlorine and saltwater, and relative humidity. Should you wear it for frequent diving operations, we recommend alternating the leather strap with rubber or NATO options. Italian artisanal straps include an 18-month warranty against manufacturing defects.
