Frequently asked questions

What is the lug width of the Tudor Pelagos M2543C1A7NU-0001?

The lug width of the Tudor Pelagos M2543C1A7NU-0001 is 22 millimetres. This dimension was engineered to accommodate wet wetsuits and accept rubber, NATO, or leather straps without adapters. Measure between the inner spring bar holes to verify exact compatibility with any aftermarket strap.

Which strap is most suitable for the Tudor Pelagos M2543C1A7NU-0001?

For genuine diving use, FKM rubber is unmatched: it resists marine oils and dries within minutes. For daily versatility, a NATO strap in Italian-made regenerated nylon offers chromatic variety and machine-washability. For urban elegance without functional compromise, choose vegetable-tanned calf leather, which develops patina over time. Avoid alligator leather: its fragility in saltwater contradicts the Pelagos's technical soul.

How do you correctly change the strap on a Tudor Pelagos M2543C1A7NU-0001?

Use a spring bar tool to push inward the two metal pins that hold the strap on the spring bar holes of the case. The old strap will slide free; insert the new one by aligning the inner holes of its lugs with the case holes, then push until you feel the spring bar click into place. Never use sharp objects like knives: you risk scratching the titanium case.

Are aftermarket straps compatible with the Tudor Pelagos M2543C1A7NU-0001?

Yes, provided they conform to the 22mm lug width specification. Milano Straps artisanal straps for 22mm fit your Pelagos perfectly, with customisation options in length and thread colour. Always verify that the lugs are generous enough to slide smoothly onto the spring bars without straining the titanium case.

How long does a leather strap last on the Tudor Pelagos M2543C1A7NU-0001?

A vegetable-tanned calf leather strap, if regularly exposed to saltwater during dives, has an average lifespan of 18–24 months before replacement. When used primarily in urban contexts and dried promptly after accidental moisture exposure, longevity extends to 3–5 years. Milano Straps offerings include 18-month warranty and can be refurbished or replaced at the Casati Milano atelier.
