Strap for Seastar 1000 Powermatic 80 40 PVD / Blue / Rubber

The lug width of the Tissot Seastar T120.807.37.041.00 is 20 millimetres. This measurement refers to the distance between the internal attachment points of the case and represents the standard for selecting compatible aftermarket straps. It is essential to measure precisely using a calliper to exclude the original attachment hardware.

The Tissot Seastar T120.807.37.041.00 accommodates multiple solutions. For sporty elegance, we recommend leather in vegetable tanning in dark brown or shell cordovan. For more aggressive contexts, a robust nylon NATO or vulcanised rubber strap accentuates the watch's diving heritage. For versatility, a calf leather with fine grain offers the best compromise between aesthetics and practicality.

To change the strap, use a spring bar tool to remove the original attachment lugs. Position the tool tip in the hole beneath the case, push gently to release the spring bar, and extract the lug. Insert the new strap by aligning the holes to the 20mm lug width and reinsert the spring bar until it clicks into place. We recommend consulting a professional to avoid damage to the case.

Yes, the Tissot Seastar T120.807.37.041.00 is fully compatible with aftermarket straps provided they have a 20-millimetre lug width. Artisanal straps crafted by specialist ateliers such as Casati Milano guarantee construction precision and zero play: they represent a reliable alternative to original Tissot straps, often with greater colour choice and material quality.

An artisanal leather strap paired with the Tissot Seastar T120.807.37.041.00 has an average lifespan of 3–5 years under regular daily use. Durability depends on the tanning method (vegetable tanned lasts longer), frequency of water exposure, and material care. A vegetable-tanned strap subjected to periodic maintenance (cleaning and conditioning) can exceed 5 years. Rubber or NATO straps offer superior durability, often exceeding 7–10 years.
