Strap for Chemin des Tourelles 42 Stainless Steel / Skeleton / Strap

The lug width of the Tissot Chemin des Tourelles T099.405.16.418.00 is 21mm. This measurement must be verified internally, between the two attachment lugs, using a digital calliper positioned perpendicular to the case axis. It is essential to confirm this dimension before purchasing an aftermarket strap, as 21mm is not a standard size for most manufacturers.

The best strap depends on intended usage and aesthetic preference. For formal elegance, we recommend a vegetable-tanned alligator (dark brown or mahogany) with a stainless steel deployante: it amplifies the case's sophistication and allows natural patina development over time. For daily versatility, a natural-coloured vegetable-tanned calf offers warmth and controlled ageing. For sports and complete water resistance, a heavyweight NATO canvas (navy blue, khaki) or textured FKM rubber ensures durability and quick changes.

The strap on the Tissot T099.405.16.418.00 is changed by removing the spring bar pins using a spring bar tool. Position the tool in the small lateral slot of the pin, apply gradual pressure to release the internal spring, then extract the pin. Insert the new strap by aligning its lugs with the same holes, reinsert the pin until you hear a slight click of engagement. Avoid sharp blows: the pins require tactile sensitivity.

Any strap with a 21mm lug width is compatible with the Tissot T099.405.16.418.00. Milano Straps offers a dedicated collection of straps in alligator, vegetable-tanned calf, shell cordovan, NATO and FKM rubber, all with 21mm lugs, customisable in colours and wrist length. All straps are ready to ship and tested for mechanical compatibility with the model.

The lifespan of a leather strap depends on material quality, tanning method and usage. A superior-quality vegetable-tanned alligator resists 3 to 5 years with regular daily use, developing patina and character. A vegetable-tanned calf typically lasts 2-4 years before requiring replacement or restoration. NATO and rubber straps last considerably longer (5-7+ years) due to the resilience of synthetic materials. Prolonged exposure to sunlight, salt water and perspiration accelerates wear: regular protection and cleaning significantly extend service life.
