Strap for Tank Anglaise 29.8 Stainless Steel / Silver / Bracelet

The lug width of the Cartier Tank W5310009 is 20mm. This measurement corresponds to the internal space between the two lugs at their seat and is standard for this model. Verification is straightforward: measure the slot where the strap connects to the case directly with a calliper.

For the W5310009, straps in alligator or vegetable-tanned calf leather represent the most aesthetically balanced choices. Alligator maintains formality, whilst calf develops characteristic patina over time. Shell cordovan offers chromatic rarity, NATO guarantees sporting practicality. The choice depends on usage and context.

The strap is changed by removing the two spring bars that secure the lug to the case. Use a spring bar tool: insert the tip into the groove of the spring, push laterally and slide the pin out. Repeat on the other side, then insert the new strap and reposition the spring bars.

Yes, any 20mm strap is compatible with the W5310009, regardless of brand. Artisanal aftermarket straps offer greater personalisation than original Cartier straps, allowing choice of leather, finishes and specific colours. Always ensure the spring bars are in optimal condition to prevent damage.

A quality leather strap on a daily-worn timepiece lasts 3-5 years before showing significant wear. Durability depends on: frequency of use, moisture exposure, material selected (shell cordovan lasts longer than calf). Regular maintenance—cleaning with a damp cloth and applying leather conditioner—extends useful life by 1-2 years.
