Strap for Style 41 Stainless Steel / Fluted / Blue-Diamond / Bracelet

The Tudor Style 12710-0017 features a lug width of 20 millimetres. This measurement represents the distance between the lugs—the pins that traverse the case at the top and bottom. The precision of this dimension allows for compatibility with any strap manufactured to this specific width, ensuring proper fit without anomalous gaps between strap and case.

The ideal strap depends on intended use. For formal occasions, vegetable-tanned alligator or shell cordovan offer inherent elegance and controlled ageing. For daily wear, calf leather in cognac or dark brown ensures durability and progressive patina development. For more relaxed contexts, fabric NATO or structured rubber straps maintain versatility without compromising technical compatibility.

Strap replacement is accomplished by extracting the spring bars that connect the lugs to the case. Using a spring bar tool (a specialised implement with a bifurcated tip), apply pressure from below upwards to release the tension of the internal spring, allowing extraction. Once the old strap is removed, the new strap is inserted by aligning the holes with the lugs and allowing the bar to protrude until the click confirms secure seating.

Any strap with a 20-millimetre lug width is technically compatible with the 12710-0017. The online collection at milanostraps.it offers straps in alligator, calf, shell cordovan, structured rubber, and NATO fabric, all available in 20mm width. The Casati Milano atelier additionally produces bespoke straps with personal selection of leathers, permitting complete customisation in terms of tone, texture, and buckle type.

Longevity depends on material quality and frequency of use. A high-quality alligator or vegetable-tanned calf strap maintains structure and water resistance for 3 to 5 years with daily wear, after which ageing becomes aesthetic but does not compromise functionality. Shell cordovan, being denser, may last 5-7 years. Rubber straps maintain elastic properties for 4-6 years, whilst NATO fabrics, being less demanding, exceed 5-8 years. Periodic maintenance (cleaning and conditioning with specific creams) significantly extends strap lifespan.
