Strap for Seastar 1000 Powermatic 80 40 Stainless Steel - Yellow Gold / Grey / Bracelet

The Tissot Seastar T120.807.22.051.00 is fitted with 20-millimetre lugs. This dimension is specific to this model and does not conform to common standards such as 22mm or 24mm. To verify, place a ruler between the two lateral pins on the case, measuring the distance from the internal attachment point of one to the other. Accuracy is essential when purchasing a compatible strap.

There is no absolute 'best', but rather choices coherent with your usage: for formal elegance, an alligator in vegetable tanning cognac dialogues with brushed steel without competing; for daily versatility, regenerated calf in dark brown tones ensures rapid patina development and ease of maintenance; for maximum technical functionality and marine environments, FKM rubber in black maintains grip when wet and dries quickly.

Remove the strap by extracting the lugs from their housings on the case, using a specialised tool (spring bar tool or lug removal tool). Position the watch with the strap side facing upward, insert the tool into the lug and apply gentle outward pressure until the lug detaches from its housing. Reverse the procedure for the new strap, ensuring the lug is firmly anchored on both sides before wearing the watch.

Yes, absolutely. Quality aftermarket straps guarantee compatibility and often exceed OEM finishes in terms of materials and craftsmanship. The key is to verify that the lug width is precisely 20mm and that the strap is constructed with robust end links (stainless steel for the deployante clasp, if present) to withstand the weight and stresses of the case.

A natural leather strap with vegetable tanning on a Seastar T120.807.22.051.00, under normal wearing conditions (not frequent immersion), maintains structural integrity for 3–5 years. Wear acceleration depends on exposure to moisture, salt water and frequency of wear. A perspiring wrist in summer shortens lifespan; regular exposure to fresh water requires rapid drying to preserve the leather.
