Strap for Style 38 Stainless Steel / Yellow Gold / Fluted / Champagne-Diamond / Bracelet

The lug width of the Tudor Style 12513-0007 is 20 millimetres. This specification is essential for selecting compatible aftermarket straps. To measure correctly, position a calliper between the inner lugs of the case, excluding the outer shoulder. Inaccurate measurement results in asymmetric fit and visual defects.

For the 12513-0007, alligator leather represents the most elegant choice, with natural ridges emphasising the yellow gold-stainless steel bicolour. Alternatively, calf leather of 1.4–1.6mm thickness offers superior softness and develops a captivating patina over time. For informal versatility, a heavy canvas NATO in grey or navy blue transforms the watch without compromising its constructive solidity.

Strap replacement requires a dedicated spring bar tool. Position the flat end into the lug groove, apply gentle pressure to disengage the internal spring, then withdraw the lug. Repeat on the other side. To install the new strap, align the lug and press until the spring locks completely. If unfamiliar with the procedure, consult a professional watchmaker to prevent case scratching.

Yes, any strap with a 20mm lug width is compatible with the 12513-0007. Quality aftermarket straps—in alligator, calf, shell cordovan or textiles—fit perfectly on the original lugs. Selection from specialised manufacturers ensures controlled construction and finish consistent with the watch's calibre. Avoid straps with mismatched thickness, which can create abnormal stress on the lugs.

A quality leather strap (alligator, calf, shell cordovan) with moderate daily wear and proper maintenance typically lasts 3–5 years before replacement. Longevity depends on intensity of use, exposure to moisture and perspiration, and tanning quality. Premium vegetable-tanned leathers, such as shell cordovan, develop magnificent patina even beyond 5 years. To extend durability, rotate the strap with alternative options (NATO, rubber) during periods of intensive use.
