Cartier
Tank WJTA0021— lug 18mm

The Cartier Tank WJTA0021 is equipped with an 18mm wide integrated lug. This measurement is specific to the model and is the result of Cartier's proportional calculations to ensure visual balance between the rectangular case and the strap. Measuring the lug correctly means positioning a caliper between the internal metal lugs without compressing, where the strap is inserted.

For the Tank WJTA0021, an alligator strap represents the most coherent aesthetic choice: the regular grain dialogues with the rectangular geometry of the case, and the patina that develops over time deposits history without aging the design. Alternatively, aniline calf leather in cognac or dark brown tones offers seasonal versatility and superior comfort, while maintaining elegance.

The Tank WJTA0021 uses standard 18mm lugs. To change the strap, simply use a spring bar tool (three-point tool) to gently compress the springs on the attachments, carefully removing the previous strap and inserting the new one. If you lack experience, Casati Milano offers a strap change service with personalized consultation.

Yes, any strap with an 18mm lug width is compatible with the Tank WJTA0021. On milanostraps.it you'll find a complete collection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm artisanal straps</a> in alligator, calf, NATO and rubber, customizable in length, initials and stitching thread.

The lifespan of a leather strap depends on usage, care, and the material chosen. A high-quality alligator strap, with proper maintenance (avoiding excessive water and humidity, conditioning periodically), guarantees 5-10 years of daily use. Casati Milano straps are covered by an 18-month warranty and are designed to develop a fascinating patina over time, increasing aesthetic value as the years pass.
