Strap for L.U.C Perpetual Chrono White Gold / Grey

The Chopard L.U.C 161973-1001 features a lug width of 20mm. This measurement corresponds to the distance between the two lugs (the shoulders of the case where the strap attaches). Do not confuse this parameter with the case diameter, which is 45mm. To verify compatibility, measure perpendicularly the distance between the two attachment points of the strap on your case.

For this complicated chronograph in white gold, we recommend high-quality alligator leather with vegetable tanning: its regular grain and evolving patina pair perfectly with the material luxury of the white metal. Shell cordovan represents the premium alternative for those seeking extraordinary durability and visual richness over time. Italian full-grain calf leather offers versatility instead, with a patina that improves with daily wear.

Changing the strap requires a specific tool called a spring bar removal tool. You must gently push inward on the strap mechanism from one side to trigger the small spring, then extract the spring bar from the other side. This process must be executed with caution to avoid scratching the white gold case. If you are unfamiliar with the procedure, it is advisable to entrust yourself to a professional watchmaker or Casati Milano, which offers the service by appointment.

Absolutely yes. Compatible 20mm straps are widely available online, including MilanoStraps' offering. Ensure that the strap has appropriate thickness and structure for a case of this importance and diameter. Avoid excessively thin straps or those constructed with poor-quality materials, which could diminish the timepiece. An strap in genuine alligator or shell cordovan ensures aesthetic solidity and durability over time.

The lifespan of a leather strap depends on the type of tanning, usage, and maintenance. A high-quality alligator or shell cordovan strap with vegetable tanning can last 5-8 years with daily wear, developing a fascinating patina over time. First-grade calf leather has a similar lifespan, typically 4-6 years. To extend the strap's life, avoid prolonged moisture exposure, occasionally apply a natural leather balm, and rotate between multiple straps if possible. The Casati Milano atelier offers an 18-month warranty and can regenerate or replace worn straps.
