Strap for De Ville Co-Axial Annual Calendar Stainless Steel / Black / Bracelet

The lug width is 20mm. This measurement corresponds to the space between the two spring bar pins of the case and is fundamental to ensure aesthetic and mechanical compatibility of any aftermarket strap. The measurement is taken by inserting a caliper between the pins to verify exactly 20mm of width.

Alligator leather in vegetable tanning represents the most coherent choice: the symmetrical texture of Nile crocodile and the pronounced grain complement the clean architectural lines of the case. Alternatively, shell cordovan offers a natural patina that evolves over time, ideal for those who appreciate leather ageing. Vegetable-tanned calf leather dyed in the mass provides lightness for summer wear while maintaining elegance.

The strap change occurs through the spring bars: using a spring bar tool (small metal implement), you press the resilient pin of the bar inward to release the spring. Extract the bar from the case and remove the old strap. Insert the new strap by aligning the holes, then push the bar until it clicks into place. The operation requires delicacy to avoid damaging the case.

Any strap with a 20mm lug width is compatible with this model. Milano Straps offers artisanal straps online in alligator, shell cordovan, vegetable calf, and natural rubber, all available in 20mm width. For a complete experience, the Casati Milano atelier creates bespoke straps with customisations, updates via WhatsApp and 18-month warranty.

A high-quality artisanal leather strap, if made with premium leathers (alligator, shell cordovan, vegetable calf), typically lasts 2-3 years with daily use. Durability depends on frequency of use, exposure to moisture, heat and the quality of stitching. A well-maintained strap alternated with other models can easily reach 4-5 years. Regular maintenance with specific creams significantly extends its useful life.
