Strap for Seastar 1000 Powermatic 80 Silicium 43 Stainless Steel / Blue / Fabric

The Tissot Seastar T120.407.17.041.01 features 21-millimetre lugs. This lug width is the standard specification for this model and ensures compatibility with straps specifically manufactured for this lug width. To verify correct measurement, position a ruler between the two holes of the watch case: the value must be exactly 21mm.

The choice depends on intended use. For formal contexts, an alligator strap with vegetable tanning is ideal, as it develops a sophisticated patina over time. For daily versatility, cognac or chocolate brown calfskin offers excellent aesthetic balance. For sports activities and water use, an FKM rubber strap or cotton NATO strap guarantees durability and practicality without compromising moisture resistance.

Strap replacement involves removing the articulation pins (also called spring bars) that connect the strap to the watch lugs. Use a spring bar removal tool to gently push the pin towards the centre, freeing one end of the strap. Repeat from the other side. Insert the pin into the new strap following the reverse order, ensuring the spring is correctly positioned. The operation takes only a few minutes and requires no special expertise.

Yes, provided the lug width is exactly 21 millimetres. Artisanal aftermarket straps, crafted by specialised workshops, often offer superior construction quality to OEM straps. Verify that the strap is made from certified materials (authentic alligator, vegetable-tanned calfskin, FKM rubber) and that stitching is regular and properly tensioned. A quality strap further enhances the sporty character of the Seastar.

Leather strap longevity depends on tanning method, usage and maintenance. Vegetable-tanned leather can last 3-5 years with moderate daily use. If frequently exposed to moisture and perspiration, durability reduces to 18-24 months. Alligator or shell cordovan straps, thanks to their denser fibre structure, tend to last longer. Regular maintenance (cleaning with damp cloth, applying leather conditioner) significantly extends lifespan. FKM rubber straps have indefinite durability if stored away from intense heat sources.
