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

The Tudor Style 12713-0021 features a lug width of 20 mm. This specification is essential for strap compatibility: it represents the distance between the case lugs where the strap attaches. All aftermarket straps must have this precise width to fit correctly without lateral play. To verify manually, measure from the inner point of one lug to the inner point of the other, perpendicular to the case.

For this two-tone gold and steel case, we suggest three solutions: black alligator to maximise the contrast and geometric elegance of the case; tobacco or cognac calf leather to create a monochromatic palette that enhances the yellow gold; black rubber if you seek practical daily wear without comfort compromises. The choice depends on your predominant usage context: the 12713-0021 accommodates all these materials gracefully, adapting equally to urban elegance and functional versatility.

The procedure is mechanically straightforward: position the watch on a soft cushion with the case facing downward, so the lugs protrude into the void. Using a flat, rounded tool (never pointed, as you risk scratching the case), gently press inward one of the lugs to release the spring bar holding it. Once freed, remove the old strap. Insert the new strap by aligning the holes, then reinsert the spring bar with decisive pressure until the click of closure. Repeat for the other lug. If you lack proper tools, consult a trusted watchmaker: the operation takes less than 5 minutes.

Yes, any 20mm strap is mechanically compatible with the 12713-0021. The variable is not lug width, but construction quality and aesthetic finish. A strap in vegetable-tanned leather with nylon or cotton stitching dramatically alters the watch's perception compared to a vinyl-coated alternative. We recommend choosing based on material (alligator, calf, rubber, textile) and finish (stitching, buckle), not compatibility alone.

Leather strap durability depends entirely on usage conditions and tanning quality. A quality vegetable-tanned calf leather, worn daily, typically lasts 3–5 years before requiring replacement. Exposure to humidity, intense perspiration, and direct sunlight reduces this lifespan. An alligator or shell cordovan strap ages more nobly, acquiring patina and becoming softer over time. Rubber or textile straps require minimal maintenance and last 5–10 years, though rubber may oxidise aesthetically. The 18-month warranty offered by Casati Milano covers manufacturing defects, not ordinary wear.
