Strap for Seastar 1000 Quartz 40 Stainless Steel / Blue / Bracelet

The lug width of the Tissot Seastar T120.410.11.041.00 is precisely 20mm, measured between the spring bar holes on the case back. This dimension is specific to this model and incompatible with standard 22mm or 24mm straps; it requires bespoke 20mm-width straps.

Selection depends on intended use. For formal versatility: alligator or vegetable-tanned calf leather. For active water use: vulcanised rubber (FKM) or robust NATO in textile with full-grain leather backing. The T120's blue dial pairs superbly with dark cordovan shell; black dial suits tobacco or cognac tones.

Use a spring bar tool on both sides of the case back. Position the tool beneath each lug, apply gentle pressure to release the internal spring, and withdraw the bar completely. Align the new strap holes with the case lugs, reinsert the bar, and press until audible engagement. Avoid excessive force to prevent case damage.

Yes, without compromise. milanostraps.it supplies artisanal 20mm-width straps in leather, NATO, and rubber, specifically compatible. Ensure the lug width matches precisely 20mm and spring bar holes align perfectly. A bespoke strap elevates comfort and aesthetic quality far beyond generic alternatives.

A quality vegetable-tanned leather strap typically lasts 2–4 years under normal conditions. Natural patina improves over time, though leather gradually thinners. For intense marine environments, alternate with rubber or NATO straps. Regular conditioning with leather-specific creams extends lifespan and preserves beauty.
