Strap for 1926 39 Stainless Steel / White / Strap

The lug width of the Tudor 1926 ref. 91550-0012 is 21 millimetres. This specific width, measured internally between the lugs, is essential for purchasing compatible straps. Use a digital calliper to verify the internal distance on the case: it must measure exactly 21mm. Even minor variations would result in fitting difficulties or undesirable aesthetic gaps.

The Tudor 1926 91550-0012 requires straps that respect the classic elegance of the case. We recommend honied or cognac alligator for aesthetic coherence with the patina of the satin-finished steel; solid-toned calf leather for understated colour contrast; shell cordovan for those seeking rich texture with significant patina development over time. We advise against NATO or rubber, which would contradict the formal language of the model. Integrated lugs demand skilled artisanal fitting.

Because the Tudor 1926 91550-0012 features integrated lugs, strap replacement is not a do-it-yourself operation. The case must be removed from the original lugs — a procedure requiring specific tools and expertise to prevent damage. We recommend an authorised Tudor service centre or the Casati Milano atelier, where skilled craftspeople perform the change whilst preserving the structural and aesthetic integrity of the case.

Yes, the 91550-0012 accepts aftermarket straps with 21-millimetre lugs, provided they feature standard lug construction (with hole for the lug pin). However, not all 21mm straps are manufactured to identical tolerances — we recommend specialised suppliers guaranteeing micrometric precision in lug positioning. Milano Straps offers 21mm straps verified for compatibility and customisable in leather, colour and stitching thread.

A natural leather strap, with daily use and routine maintenance, maintains structural integrity between 3 and 5 years. Longevity depends on tanning method (vegetable versus chromium), sun exposure, environmental humidity and cleaning frequency. Vegetable-tanned leather develops visible patina within 6 months of wear; chrome-tanned leather maintains colour more consistently. Casati Milano guarantees artisanal straps for 18 months, covering natural wear. A well-maintained strap, protected from impacts and periodically softened, can achieve 7–8 years of useful life.
