Strap for De Ville Trésor Tourbillon Canopus Gold / Pink

The lug width is 21mm. It is essential to measure precisely the distance between the case attachment points—between the two lugs—to ensure that the strap fits perfectly without gaps or excessive pressure.

Dark brown or black alligator leather is the most elegant and versatile choice: the natural grain pairs beautifully with the cool and luminous tone of Canopus Gold. Alternatively, vegetable-tanned calf leather offers a patinated aging over time, ideal for those who desire the strap to develop personal character.

The strap is replaced by removing the spring bars using a dedicated spring bar tool. Carefully position the pin from the base outward, completely free the used strap, then insert the new one aligning it perfectly in the lug holes. Ensure that the spring bar clicks fully into place, checking the fit with a slight rotation.

No, the 21mm lug width is specific and does not allow variations. A 20mm or 22mm strap will not fit correctly in the lug seat, causing excessive play or installation failure. It is essential to respect the original manufacturing tolerance.

A high-quality alligator or calf leather strap with vegetable tanning lasts an average of 3-5 years of daily use, developing patina and character. Longevity depends on sun exposure, perspiration, and ambient humidity. The Casati Milano atelier offers an 18-month warranty and recommends annual maintenance with natural leather conditioning.
