Strap for De Ville Power Reserve Master Chronometer Stainless Steel / Salmon

The lug width of the De Ville 434.13.41.21.10.001 is 19 mm. This dimension is precise and allows no variation: 20 mm straps create lateral play, while 18 mm straps risk rubbing on the case. We recommend verifying with a digital caliper positioned perpendicularly to the lug, measuring its interior.

It depends on your style and occasion of use. American alligator offers timeless elegance and a unique patina that develops over time. Shell cordovan guarantees extraordinary durability and a warm tone that develops with aging. Vegetable-tanned calf is the conscious and sustainable choice. A blue or black NATO is ideal if you desire a sportier interpretation of the model.

The procedure requires a specific tool (Spring Bar Tool). Position the watch securely, insert the tool into the lateral opening of the lug to compress the internal spring, then remove the original strap. Insert the new 19 mm strap ensuring the spring clicks correctly into place. We recommend entrusting this to an expert if you prefer to avoid the risk of damage to the case.

Absolutely yes. Aftermarket 19 mm straps are fully compatible with your watch. On milanostraps.it you will find a selection of noble leathers and artisanal finishes specific to this lug width. What matters is choosing straps built with quality equivalent to the Omega case, to maintain aesthetic and functional harmony.

The lifespan depends on the material and use. An alligator or shell cordovan, with regular maintenance, lasts 3-5 years before requiring aesthetic replacement, although it remains functional beyond that. Calf is more delicate and tends to show signs of use after 18-24 months of intensive wear. Vegetable-tanned straps age visibly but maintain structural integrity longer. The 18-month warranty from Casati Milano covers manufacturing defects within this period.
