Strap for De Ville Trésor Master Co-Axial Sedna Gold / Silver Diamond

The lug width is 20mm, which is the exact distance between the two lugs on the case where the strap attaches. You can verify this by measuring with a caliper the internal distance between one lug and the other. This measurement is essential for purchasing compatible straps.

We recommend black or dark brown alligator for formality, vegetable-tanned calf leather in warm tones for everyday elegance, or burgundy shell cordovan for those who desire dynamic patina over time. Sedna Gold pairs particularly well with straps in deep tones or champagne, depending on whether you prefer contrast or chromatic continuity.

The change requires a simple tool called a spring bar tool. Insert the tip of the tool into the small hole on the side of the lug, pushing inward to release the internal spring of the lug. Remove the old strap and insert the new one by snapping the spring into its proper seats. If in doubt, contact Casati Milano for a professional strap change.

Yes, if you purchase straps with 20mm lug width. All our straps in the 20mm collection are compatible with the Trésor 432.53.40.21.52.002. In the product sheet you will always find the lug width specified; make sure to select exactly 20mm.

A quality leather strap, with daily use, typically lasts 3-4 years before requiring replacement. Durability depends on frequency of use, exposure to sun and humidity, and the type of tanning. Vegetable tanning tends to last longer than chrome tanning. Our artisanal straps, with ordinary care, exceed this threshold thanks to their thickness and careful craftsmanship.
