Cartier
Tank W5200027— lug 18mm

The lug width of the Cartier Tank W5200027 is exactly 18 millimeters. This measurement is specific to the model and corresponds to the internal gap of the integrated lug on the case. It is essential to use 18mm straps to ensure precise fit and avoid lateral play that compromises the aesthetics of the timepiece.

The best strap depends on use: mississippi alligator in black or dark brown offers pure elegance and natural grip; full-grain calf develops a unique patina over time; ballistic cotton NATO provides chromatic versatility; FKM rubber is ideal for humid environments. The choice must respect the architectural sobriety of the Tank, favoring neutral or warm tones.

The change requires the use of a specific tool to extract the lug pins. Position the Tank on a soft surface, locate the lateral pin with opening facing downward (stamped on the case), insert the removal tool and gently push the pin outward. Repeat for both sides, then insert the new strap ensuring the pins are fully seated.

Yes, any strap with an 18 millimeter lug width is compatible with the W5200027, provided the pins have the same shoulders (standard Cartier measurement). High-quality artisanal straps offer customization opportunities in leather, color and stitching that original straps do not allow, while maintaining full mechanical compatibility.

A full-grain leather strap of artisanal quality lasts between 5 and 8 years with daily use, developing a fascinating patina. Longevity depends on exposure to humidity, leather breathability and maintenance. The Casati Milano warranty is 18 months. Beyond this period, regeneration is possible through specific treatments or leather replacement while maintaining the original stitching.
