Strap for De Ville Trésor Master Co-Axial Yellow Gold / Ivory Enamel Diamond

The lug width of the Trésor 432.53.40.21.59.001 is 20mm. This width is the standard for the model and allows the use of all handcrafted straps with 20mm lug width available in the MilanoStraps catalog, from classic alligator to more modern materials such as synthetic rubber.

For a dress watch in 18-karat yellow gold such as the Trésor, black alligator represents the most elegant and traditional choice, thanks to its fine grain texture that enhances the shine of the metal without competing with it. Sophisticated alternatives include vegetable-tanned calf in dark brown tones or shell cordovan for those desiring greater durability over time.

To change the Trésor strap, use a dedicated tool (spring bar tool) to compress the elastic pins that secure the old strap in the case lugs. Gently lever out the strap, then insert the new 20mm strap ensuring the pins snap correctly into their housings. If you are not experienced, contact a specialized service center.

All handcrafted straps with 20mm lug width are compatible with the Trésor. MilanoStraps offers a customizable range in alligator, calf, shell cordovan and rubber, with initials and stitching thread options. Always verify the correct width (20mm) to avoid incompatibility.

A quality leather strap (alligator, vegetable-tanned calf or shell cordovan) typically lasts 3-5 years with moderate daily use, up to 7-10 years if carefully maintained and used occasionally. MilanoStraps straps benefit from an 18-month warranty and develop an aged patina that increases aesthetic value over time, especially with vegetable-tanned cordovan.
