Strap for Tank Française Extra-Large (XL) W51023Q3

The lug width of the Cartier Tank Française W51023Q3 is 22 mm. This is the net distance between the centres of the attachment holes on the metal lugs of the case. This is a specific measurement for this model, and any aftermarket strap must respect this width with precision to ensure proper fit without play or misalignment.

Black alligator is the reference choice for the W51023Q3, the option proposed by official Cartier boutiques. If you prefer practicality and lower costs, calf leather with vegetable tanning in medium brown tone offers formal elegance and develops a natural patina over time. For a more casual approach, a NATO strap in heavy cotton or synthetic silk transforms the watch into a versatile companion.

The W51023Q3 strap is secured by two metal lugs protruding from the case. To remove the existing strap, insert the tip of a blunt tool (such as the strap remover supplied with milanostraps purchases) into the small hole at the shoulder of the lug, then gently pull downward. The new strap with the same 22 mm lug width simply inserts in reverse. If you lack experience, Casati Milano offers a replacement service with personalised consultation.

No. Although 22 mm is the lug width, Cartier Tank Française straps require a specific shape on the terminals and lugs to fit correctly. Straps from milanostraps are tested on this model and guarantee perfect fit without play. A generic 22 mm aftermarket strap may not fit properly or could cause damage to the delicate case lugs.

An alligator strap of quality lasts 5 to 7 years with daily use, provided water exposure is avoided and any splashes are dried quickly. A calf strap lasts 3 to 5 years under the same conditions. Casati Milano offers an 18-month warranty on all handcrafted straps and performs reconditioning to extend their lifespan.
