Cartier
Tank WSTA0052— lug 16mm

The Cartier Tank WSTA0052 has a lug width of exactly 16mm. This measurement is specific to this reference and non-negotiable. To verify, measure the internal distance between the two side lugs of the case where the strap attaches. Measurement error will result in mechanical incompatibility.

Alligator remains the optimal choice to maintain the Tank's formal identity. Recommended shades: black, burgundy, or navy blue to maximize contrast with the steel case. Box calf is an elegant and more accessible alternative. NATO straps are not recommended as the additional loop conceals the case's iconic silhouette.

The Tank uses standard integrated lugs. Proceed as follows: position the watch with the case facing upward, locate the small metal rod (spring bar) hidden between the case and the old strap on each side. Using a specialized spring bar tool, gently press the rod toward the case to compress the internal spring, then remove the old strap. Insert the new strap by sliding the rod into the new hole, allowing it to return to the locked position.

The straps offered on milanostraps.it are artisanal aftermarket straps, crafted in premium leather (alligator, calf) specifically sized for the 16mm lug width. They are not official Cartier products, but offer superior quality and customization impossible in the OEM market. Each strap is made to order with an 18-month warranty at the Casati Milano atelier.

A quality leather strap (premium alligator or calf) typically lasts 3-5 years with daily use and proper maintenance. Durability depends on exposure to moisture, sweat, and heat sources. To extend service life: avoid prolonged water contact, apply leather cream every 6 months, store in a cool and dry place. Visible leather wear (patina, micro-creases) is natural and a prized characteristic.
