Strap for Style 41 Stainless Steel / Yellow Gold / Silver-Diamond / Strap

The lug width of the Tudor Style 12703-0011 is 20mm. This measurement refers to the distance between the two lugs on the case and determines compatibility with aftermarket straps. It is essential to measure correctly: position a calliper between the inner edges of the lugs, not along the length of the strap itself.

For the stainless steel and yellow gold two-tone 12703-0011, alligator represents the most harmonious choice: its natural grain and patina integrate seamlessly with the fluted bezel. Recommended colours: warm cognac, hazelnut brown, or smoked grey. Calf leather is a versatile alternative in cognac or tobacco tones. For a sporty approach, a canvas NATO strap with calf underlay maintains aesthetic balance.

Position the watch on a soft pad. Use a strap removal tool, inserting the flat tip under the spring bar's internal spring. Push gently outward to release one end, then the other. Remove the old strap. Align the new strap with the lugs and reinser the spring bar from one side (pushing the internal spring downward), then close from the other side, ensuring the bar is firmly seated.

All straps with 20mm attachment points are compatible: alligator, calf leather, shell cordovan, canvas NATO, vulcanised rubber, technical fabrics. Verify that the strap is specifically designed for 20mm lug width. Custom straps from Casati Milano guarantee precision in craftsmanship and personalised fitting to your case.

A quality leather strap, worn daily on a two-tone watch such as the 12703-0011, typically lasts 3–5 years. Factors affecting longevity include: frequency of wear, exposure to perspiration, humidity, tanning quality, and maintenance (drying after rain, occasionally applying dedicated balms). Alligator ages better than calf, developing a more compelling patina. The 18-month warranty on Casati Milano straps covers manufacturing defects.
