Frequently asked questions
What is the lug width of the Tudor Pelagos M25827KN?
The Tudor Pelagos M25827KN features a lug width of 22 mm. This measurement is critical for aftermarket strap compatibility. To verify accurately, use a digital caliper to measure the distance between the inner points of the lugs—it must read exactly 22 mm. Any deviation will compromise strap fitment to the case.
Which strap is best suited for the Pelagos M25827KN?
Selection depends on intended use. For technical diving, FKM rubber is recommended: absolute waterproofing, thermal resistance from -40°C to +100°C, and zero maintenance. For daily elegant wear, dark brown or grey pearl alligator ensures brine resistance and develops patina progressively. Optimal thickness is 4–5 mm to balance durability and wrist comfort.
How do I change the strap on the Tudor Pelagos M25827KN?
Position the watch on a soft pad. Using a spring bar tool, gently press the lower pin towards the case centre to release the tension spring. Remove the old strap, then insert the new one by aligning the pins with their respective seats. Verify the strap is secure by applying gentle pressure.
Can I fit an aftermarket strap on the M25827KN?
Yes, absolutely. Any 22 mm strap is compatible. Ensure thickness does not exceed 5 mm to avoid friction against the case. Our artisanal straps are specifically engineered for tool watches like the Pelagos: they deliver marine durability and finishes that enhance the titanium without aesthetic compromise.
What is the lifespan of a leather strap on the Pelagos M25827KN?
With vegetable-tanned leather, average lifespan is 18–24 months under daily wear. Regular air exposure, avoiding moisture accumulation, and applying vegetable wax every 4–6 months extends life to 36 months. Rubber, by contrast, resists degradation for 4–5 years without maintenance, ideal for those rejecting recurring servicing.
