Frequently asked questions

What is the lug width of the Tudor Pelagos 25707B/23-0001?

The Tudor Pelagos 25707B/23-0001 features a lug width of 22 millimetres. This dimension is specific to this model and accommodates robust straps such as NATO, rubber, and leather with 1.8mm thickness. Accurate measurement from lug to lug is essential to prevent mechanical play that could compromise the movement over time.

What is the best strap for the Tudor Pelagos 25707B/23-0001?

For the titanium Pelagos 25707B/23-0001, we recommend premium recycled NATO straps as the primary choice: they absorb post-immersion moisture without damaging the titanium case and maintain a uniform weave that prevents micro-scratching. Alligator with vegetable tanning remains a classic option for daily wear, whilst vulcanised SBR rubber straps are ideal for pure diving environments.

How do I change the strap on the Tudor Pelagos 25707B/23-0001?

The Tudor Pelagos 25707B/23-0001 uses a standard dual-lug system (22mm width). To change the strap: extract the Spring Bars on both sides of the case using a dedicated tool (Spring Bar remover), slide out the old strap, insert the new strap through the lugs and reinsert the Spring Bars until they click firmly. Verify that the lugs are stable before wearing the watch.

Are there compatible aftermarket straps for the Tudor Pelagos 25707B/23-0001?

Yes, any strap with a 22mm lug width is compatible with the Tudor Pelagos 25707B/23-0001. However, we recommend straps made from quality leather or premium NATO: the titanium case has specific vibration characteristics and quality straps absorb micro-oscillations better without creating concentrated stress points. Avoid budget straps with inconsistent lug thickness.

How long does a leather strap last on the Tudor Pelagos 25707B/23-0001?

A quality alligator or calf leather strap with vegetable tanning typically lasts 3–4 years with regular use (3–4 times weekly). Durability depends on sun exposure, post-immersion moisture and cleaning frequency. If you wear the Pelagos daily in a marine environment, we recommend rotating between two straps to extend the life of both to 5–6 years. Vulcanised rubber lasts 5–7 years under normal conditions.
