Strap for Style 38 Stainless Steel / Yellow Gold / Silver-Diamond / Strap

The Tudor Style 12503-0011 features a lug width of 20mm. This measurement is fixed and precise—it is the distance between the two lugs that attach the strap to the case. Any strap certified as 20mm compatible will fit this model correctly.

For the yellow gold and stainless steel two-tone case, we recommend cognac-brown alligator, vegetable-tanned shell cordovan for evolved character, or grain calf with stainless steel deployante. For sports contexts, a grey or black NATO remains a contemporary alternative. Structured vulcanised rubber creates interesting contrast without chromatic competition with the case.

Strap replacement requires minimal tools: a spring bar tool and a soft cloth beneath the watch. Locate the two elastic pins on either side of the case, insert the tool horizontally to release the pin on one side, remove the old strap, then insert the new strap's pins by clicking first one side, then the other. If unsure, a professional watchmaker completes this task in minutes.

Yes, provided the strap is certified for 20mm width. Lug width is the only parameter that matters: the strap's pins engage the case lugs via universal elastic spring bars. Any well-constructed 20mm strap, regardless of brand, will work perfectly. Milanostraps offers a selection of artisanal 20mm-compatible straps.

A quality leather strap—using materials such as alligator or shell cordovan—typically lasts 3–5 years with daily wear, considering sun exposure, perspiration, and climate variations. Calf grain lasts 2–4 years. Longevity increases significantly with care: allow drying after water contact, avoid prolonged moisture, protect from direct sunlight for extended periods. Casati Milano straps include an 18-month warranty.
