The Ranger 79910-0011 (aka: M79910-0011), seen from the bench

The Tudor Ranger 79910-0011 is a contemporary field watch that embodies Tudor's military heritage, featuring a 41mm stainless steel 316L case with austere black dial and minimalist indices. It houses the ETA 2824-2 automatic movement with 25 jewels and date window, offering 100m water resistance and a screw-down caseback. The 20mm lug width is standard for this family and requires precise compatibility when selecting a replacement strap, with straight parallel lugs typical of British military construction.

Frequently asked questions

What is the lug width of the Tudor Ranger 79910-0011?

The lug width of the Tudor Ranger 79910-0011 is 20mm. This is the international standard for mid-to-large sports and field watches, and is essential to ensure perfect fit of the strap to the case lugs.

What is the best strap for the Tudor Ranger 79910-0011?

Choice depends on intended use. For formal elegance, we recommend black alligator with contrasting stitching. For daily robustness, brushed calf or shell cordovan aged in vegetable tanning. For tactical or diving contexts, FKM vulcanised rubber offers a decade of durability with zero maintenance. Ballistic nylon NATO straps are historically authentic and practical for rotation.

How do you change the strap on a Tudor Ranger 79910-0011?

The Ranger uses simple-end spring bars. Use a dedicated spring bar tool to compress the internal elastic pin, sliding the old strap outward. Once both lugs are freed, align the new strap and reinsert the spring bars until they click into position. Proceed carefully to avoid scratching the case.

Is a 20mm aftermarket strap compatible with the Tudor Ranger 79910-0011?

Yes, any strap manufactured to 20mm lug width is mechanically compatible. However, we recommend straps built to high quality standards: stitching must be even, the buckle (or deployant clasp) well-plated, leather passants of consistent thickness. Specialist ateliers such as Casati Milano guarantee bespoke construction and longevity.

How long does a leather strap last on the Tudor Ranger 79910-0011?

A quality leather strap with vegetable tanning and bespoke construction typically lasts 5-7 years of daily wear, varying with humidity, frequency and care. The ageing patina (typical of vegetable-tanned leather) keeps the strap visually attractive even after years. A rubber strap lasts 10+ years. Bespoke warranty (18 months with Casati Milano) covers manufacturing defects.
