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

The lug width of the Tudor Style 12510-0011 is 20 millimetres. This measurement represents the distance between the two pins that attach the strap to the case. To verify the compatibility of an aftermarket strap, position the strap lug against the space defined by the case lugs without forcing. A precise 20mm measurement is essential to avoid overlaps or unwanted play.

There is no single best choice, as it depends on usage and personal preference. For formal elegance, black or dark brown alligator represents absolute excellence. For everyday versatility, vegetable-tanned calf leather in cognac or warm brown tones allows natural ageing and patina development over time. For sporting or marine contexts, a NATO or technical rubber strap maintains aesthetics whilst ensuring practicality. What matters is ensuring the width is exactly 20mm for a correct fit.

The procedure requires a specific tool called a spring bar tool (or strap remover). Position the Tudor on a clean surface. Using the spring bar tool, gently press the internal spring of the left lug pin to release the bar. Once released, extract the pin itself. Repeat on the other side. Insert the new strap by aligning its ends with the holes, then push the pins until they click into place (you will feel a slight click). The operation takes approximately 2-3 minutes and requires no special skills.

Absolutely. Quality aftermarket straps made for the 20mm lug width fit the Tudor Style 12510-0011 perfectly. Compatibility depends solely on pin width and strap lug geometry. Specialist brands offer solutions in alligator, calf, NATO and rubber with guaranteed dimensional precision, impeccable finishing and superior materials. A handcrafted vegetable-tanned strap can even further enhance the elegant character of the watch.

Durability depends on material, tanning method and intensity of use. A quality alligator or calf strap, worn daily without neglect, lasts 3 to 5 years. If worn occasionally, lifespan extends to 7-10 years. Factors that shorten strap life include frequent sweating, direct sun exposure, repeated freshwater immersion and constant humidity. Conversely, vegetable-tanned leather ages beautifully, developing patina and character, and can be refinished without structural compromise. The standard warranty for handcrafted straps is 18 months.
