Strap for Style 38 Stainless Steel / Fluted / Blue-Diamond / Bracelet

The Tudor Style 12510-0017 features a 20-millimetre lug width. This measurement represents the distance between the two metal pins that secure the strap: it is the critical dimension needed to purchase compatible straps and ensure precise fit without rotational play.

The choice depends on intended use: for absolute formality, an alligator strap in vegetable-tanned leather in cognac brown creates elegant chromatic dialogue with the polished steel case. Black calfskin offers everyday versatility, whilst navy blue NATO provides operational character consistent with the brand's heritage. Shell cordovan represents maximum accelerated patina development and visual longevity.

Locate the two lateral metal pins holding the strap to the case: one is typically removable (with small lateral hole for tool extraction), the other fixed. Extract the removable pin using a spring bar tool, slide the old strap towards the wrist, insert the new strap, and reinsert the pin correctly. Simple operation requiring maximum care on the satin-finished case.

Absolutely. The 20-millimetre lug width is standard in quality aftermarket strap production. Always verify that the strap is designed for this lug width (some manufacturers specify overall strap width separately, which varies from 18 to 22mm depending on artisanal construction). Custom-made artisanal straps offer superior fit and personal patina development.

A quality alligator or calfskin strap, constructed with traditional vegetable tanning, resists 3-5 years of intensive daily wear before requiring replacement for aesthetic reasons (fibre degradation, base colour oxidation). Actual longevity depends on wear frequency, ambient humidity, and maintenance (regular soft cloth cleaning, immediate air-drying after water exposure). Shell cordovan, thanks to dense fibre structure, exceeds 6-8 years whilst maintaining structural integrity.
