Strap for De Ville Prestige Automatic 36.5 Stainless Steel / Yellow Gold / Silver / Bracelet

The lug width of the De Ville 4312.21.00 is exactly 20 millimeters. You can verify it by measuring from the inner point to inner point of the case where the strap attaches. This dimension ensures compatibility with all standard 20mm straps available on the market.

For this two-tone yellow gold and steel model, dark brown alligator is the classic choice that maintains the original formal elegance. Excellent alternatives are vegetable-tanned calf (versatile for multiple contexts) or shell cordovan if you desire a leather with a lasting patina and distinctive character.

Changing the strap requires a specific tool to remove the spring bars from the lugs. With the 20mm model, gently push the spring in one direction, extract the bar and repeat on the other side. Insert the spring bars into the new strap and secure to the case. If you are unsure, it is advisable to contact an expert to avoid damage.

Yes, absolutely. As long as they respect the 20mm lug width, aftermarket straps are completely compatible and offer greater versatility compared to the original bracelet. Milano Straps offers a selection of customizable 20mm leather straps in various colors and finishes.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily use, depending on the tanning method and climate. Vegetable tanning tends to develop a refined patina over time. Milano Straps offers an 18-month warranty on all artisanal straps, with the possibility of restoration and repair.
