Strap for Seastar 1000 36 Quartz Stainless Steel - Rose Gold / MOP / Bracelet

The lug width of the Tissot Seastar T120.210.22.111.00 is 18mm. This measurement is specific to the 36mm case model and is critical for compatibility with any replacement strap. The measurement is taken internally, measuring the distance between the case lugs.

For the Seastar T120.210.22.111.00, we recommend alligator straps with vegetable tanning for formal elegance, calf leather with pronounced texture for daily wear, or shell cordovan for special occasions. NATO remains a sporting option, whilst FKM rubber ensures maximum practicality without compromise. Your choice depends on intended use and personal aesthetic preference.

Strap replacement is performed by removing the connecting pin that passes through the case lugs, using a dedicated tool or small flat-head screwdriver. Gently extract the old strap, insert the new one ensuring the ends are perfectly aligned with the lugs, and reinsert the pin until firmly secured. For precision work, we recommend consulting a qualified watchmaker.

Yes, numerous quality aftermarket straps are compatible with the 18mm lug width of the Seastar. Alligator leather, calf, shell cordovan, military NATO and technical rubber are available from specialised suppliers. Always ensure the lug width is precisely 18mm and that total length respects the proportions of the 36mm case.

A quality vegetable-tanned leather strap has an estimated lifespan of 3-5 years with daily wear, varying based on usage, sun exposure and maintenance. Vegetable tanning develops natural patina and wear, characteristics appreciated by enthusiasts. Shell cordovan offers greater longevity (5-7 years), whilst alligator and calf are estimated at 4-6 years. FKM rubber may last 2-3 years before hardening occurs.
