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

The lug width of the Tudor Style 12513-0015 is 20 millimetres. This dimension represents the spacing between the strap lugs on the case and must be measured with millimetre precision to ensure compatibility. Position a measuring scale orthogonally to the lugs and measure the external distance: visual estimation leads to errors. An incorrect measurement would cause strap instability and lateral slippage during wear.

The ideal strap depends on intended usage context. For formal aesthetics, we recommend alligator in deep black or burgundy tones: the natural grain balances the bicolour richness of the case. Shell cordovan in warm cognac enhances the yellow gold and develops a unique patina over time. For a more casual approach, vegetable-tanned calf offers discreet elegance and natural ageing. FKM rubber remains the choice for humid environments and sporty use, guaranteeing a decade of durability.

Strap replacement requires a spring bar tool (cross tool or dedicated pincer). Place the watch on a flat, well-lit surface. Insert the flat end of the spring bar tool into the small hole adjacent to the lug, applying gentle lateral pressure: the spring bar will retract slightly, allowing extraction from its seat. Repeat on the opposite lug. To install the new strap, align the holes to the lug ends and push the spring bar until it clicks: this confirms secure anchoring.

Yes, the 12513-0015 is fully compatible with premium aftermarket straps in 20mm width. Milanostraps.it offers an extensive range of materials (alligator, calf, shell cordovan, NATO) customisable in length, initials and stitching thread. Compatibility is guaranteed by the standardised lug width: any 20mm strap will fit mechanically, although construction quality, finishing and buckle hardware will vary depending on supplier and price point.

Durability depends on leather quality and wear patterns. A premium alligator or shell cordovan strap with vegetable tanning can last 5–10 years with regular maintenance (routine cleaning, drying after moisture exposure, avoiding intense mechanical stress). More delicate calf leather has a useful life of 3–5 years. FKM rubber exceeds 10 years of durability under any condition. Factors such as constant perspiration contact, direct sun exposure and daily wear accelerate ageing. The Casati Milano atelier provides an 18-month warranty on all custom straps.
