Strap for De Ville Hour Vision Co-Axial Stainless Steel / Blue / Orbis

The lug width of the De Ville 431.33.41.21.03.001 is 22 millimetres. This measurement refers to the free space between the inner shoulders of the case lugs. To verify it, measure the distance between the internal contact points of the lugs with a ruler: it must be exact to 1 millimetre for a correct strap fit.

The best strap depends on intended use. For formal occasions, we recommend black or dark brown alligator, which enhances the deep blue dial and gold indices. For daily versatility, vegetable-tanned calf develops a natural patina over time. The sporty option remains canvas NATO, ideal for summer, whilst grey or anthracite rubber ensures grip and durability in humid environments.

Strap change involves removing the spring bars that connect the strap to the lugs. Use a spring bar tool to gently compress the pin from underneath, then extract it. Insert the new strap by aligning the lug holes with the spring bar and reinsert the pin until it clicks. Never force movements to avoid damaging the case.

Yes. The De Ville 431.33.41.21.03.001 with 22mm lugs is compatible with all 22mm artisanal straps on the market. On milanostraps.it you will find a selection of 22mm straps made from alligator, calf, NATO and rubber, customisable for size and finishes, ready for shipment.

The lifespan of a leather strap depends on frequency of use, tanning method and leather quality. A vegetable-tanned calf of good quality guarantees 3-5 years of daily use, maintaining aesthetics and function. Alligator, thanks to denser fibre structure, can last 5-7 years. Rubber, more resistant to wear, reaches 4-6 years. Casati Milano offers an 18-month warranty on every handmade strap.
