Strap for Big Crown Pointer Date 40 Stainless Steel / Red

The lug width of this model is 20mm, measured as the distance between the spring bar pins that attach the strap to the case lugs. This dimension is proportioned to the 40mm case diameter and ensures both aesthetic balance and mechanical compatibility with all straps specified for this width.

The choice depends on intended use. For formal settings, a black or dark brown alligator strap highlights the understated quality of the oversized crown. For a sport-casual approach, a khaki or navy NATO strap echoes the aviator heritage. A vegetable-tanned calf strap offers an elegant compromise between formality and daily wearability, developing natural patina over time.

Position the watch on a soft pad. Use a spring bar tool to apply gentle, uniform pressure on the top lug pin, extracting it carefully from the lug. Repeat for the lower pin. Insert the new pins into the replacement strap and reinsert them into the lugs, verifying the locking click. Avoid pointed tools that could scratch the stainless steel.

Milanostraps.it offers artisanal-quality straps (genuine alligator, calf leather, NATO fabric, and vulcanised rubber) compatible with the 20mm lug width, manufactured to industrial precision standards. These are not official Oris products, but high-end aftermarket straps, interchangeable on any watch with a 20mm lug width.

A quality alligator or calf strap typically lasts 3-5 years with daily wear, varying according to climate, frequency of use, and maintenance. Vegetable-tanned leather develops characteristic patina but the fibres gradually thin. Storing the strap in dry conditions, avoiding prolonged exposure to moisture and perspiration, and regular conditioning significantly extend its service life.
