Strap for De Ville Power Reserve Master Chronometer Sedna Gold / Silver

The lug width for this model is 19mm. You can verify it by measuring the distance between the vertical lugs of the case using a digital caliper. The 19mm width is specific to De Ville models with a diameter of over 39mm and ensures harmonious proportions on the wrist.

Alligator remains the classic choice for this dress model: its natural texture and the patina that evolves over time pair perfectly with Sedna Gold. Equally elegant is vegetable-tanned calf leather, which offers a softer and more intimate appearance. For transitional seasons, a raw linen NATO or black technical rubber represent versatile options.

Use a spring bar tool (a small specific lever) to push the internal spring bar and release the pin that fastens the strap to the lug. Position yourself in a well-lit area and protect your eyes, as the pins are very small. If you are not experienced, the service is available at any watchmaker or at Casati Milano, which offers quick replacement.

Yes, provided the strap is genuinely 19mm (not 18 or 20mm, which would cause visible gaps or overhang). The best compatible aftermarket straps are those custom-made by specialized workshops like Casati Milano, which guarantee construction quality and durability over time with customization options.

It depends on the quality of the leather and usage. A high-quality alligator or shell cordovan strap (such as those made with vegetable tanning) lasts 3-5 years with regular maintenance: regular cleaning, avoiding prolonged moisture, and applying protective balms every 6-8 months. Traditional calf leather may require replacement after 2-3 years. Casati Milano guarantees 18 months on all custom straps.
