Tudor
Ranger 79910-0012— lug 20mm

The lug width of the Tudor Ranger 79910-0012 is 20mm. This is measured internally between the two attachment points on the case. This size is specific to this model and is not standardised in wholesale catalogues, so it is essential to verify it before purchasing an aftermarket strap.

The best strap choice depends on your use case. Alligator offers subtle elegance and natural ageing; vegetable-tanned leather develops patina over time; NATO is the robust operational choice; FKM rubber is practical for humid environments. We recommend dark brown alligator or black vegetable-tanned leather for aesthetic coherence with the Ranger's black dial.

Strap replacement is performed by removing the attachment pins from the case lugs. Use a spring bar tool to compress the inner pin, insert it into the lug hole, and gently lever it free. Once the pin is released, extract the strap. Repeat for the other pin. Installation of the new strap follows the reverse procedure. Avoid forcing to prevent damage to the lugs.

An aftermarket strap is compatible if it has an exactly 20mm lug width. Verify the seller's specifications. Quality aftermarket straps use standardised 20mm lugs, crafted from premium leathers such as alligator, shell cordovan, and vegetable-tanned calf. The Ranger also accepts NATO and rubber straps with specific adapters.

A quality leather strap typically lasts 18-36 months with daily use, varying based on tanning method and leather type. Vegetable-tanned leather tinted in the barrel ages elegantly and can exceed 3 years if maintained. Alligator offers superior durability. We recommend periodic replacement for hygiene and aesthetic performance. Casati Milano offers an 18-month warranty on bespoke straps.
