Frequently asked questions

What is the lug width of the Tudor Ranger 79910-0013?

The Tudor Ranger 79910-0013 features a lug width of 20 millimetres. This measurement is standard for the model and determines the inner diameter of the pins onto which the strap attaches. Always verify the measurement before ordering an aftermarket strap to ensure mechanical compatibility.

What is the best strap for the Tudor Ranger 79910-0013?

The choice depends on primary usage. For authentic tool watch aesthetics, we recommend polished alligator in black with cream topstitching—it preserves the minimalist character of the case. For refined daily wear, Italian vegetable-tanned calf in medium brown tone develops natural patina over time. FKM rubber remains ideal for humid climates or sporting activity, whilst NATO canvas is perfect for those who frequently rotate straps across contexts.

How do you change the strap on a Tudor Ranger?

The Tudor Ranger utilises standard pins. Use a dedicated pin remover tool to gently push the pin from one side to the other, always supporting the previous strap to prevent accidental loss. Position the new strap, align the holes with the pin ends, and insert the pin until you feel a light click. Never force: the pin must slide with precision, not violence.

Can I use aftermarket straps on a Tudor Ranger 79910-0013?

Yes, any strap with a 20mm lug width can be used, provided it is manufactured with correct pin hole diameters. High-quality artisanal straps guarantee precise tolerances and superior materials compared to generic options. Always verify that the strap has been shaped for a 41mm case to achieve the exact aesthetic match.

How long does a leather strap last on the Tudor Ranger?

The lifespan of a leather strap depends on usage and tanning quality. An artisanal-quality alligator or calf strap with vegetable tanning typically lasts 18–24 months of daily wear before requiring replacement. Patina and natural wear are valued characteristics, not defects. Artisanal warranty covers manufacturing imperfections for 18 months; wear is considered the natural evolution of leather.
