Strap for Seastar 1000 Chronograph Quartz 45.5 Rose Gold / Black / Rubber

The lug width of the Tissot Seastar T120.417.37.051.00 is 22mm. This measurement represents the distance between the two attachment points of the case lugs and determines compatibility with aftermarket straps. To verify accurately, measure perpendicular to the inner edges of both lugs using a digital calliper or precision ruler.

The optimal choice depends on intended use: for formal elegance, vegetable-tanned tropical alligator or Italian napped calf leather are recommended. For sports and aquatic applications, ballistic nylon NATO or vulcanised natural rubber offers superior resistance and rapid drying. The 45.5mm case diameter supports robust materials; avoid excessively thin straps that would create unbalanced proportions.

The T120.417.37.051.00 features standard lugs with grooves. Use a spring bar tool to compress the small metal pins (spring bars) that retain the strap in the case lugs. Insert the tool into the lateral spaces beneath the lugs, gently compress the pin, remove the old strap, and insert the new one. No specialised tools are required for standard 22mm straps. If selecting a deployante clasp, verify mechanical compatibility with your case lugs.

Any strap with a 22mm lug width is compatible. This includes leather straps (alligator, calf, cordovan), fabric NATO, rubber, suede, and innovative materials. Always verify that your spring bar tool has been engineered to avoid scratching the stainless steel and aluminium case. Premium straps featuring a deployante clasp ensure superior comfort and security.

A premium vegetable-tanned leather strap (alligator, calf) typically lasts 3–5 years with daily wear, provided minimal maintenance: light cleaning with a damp cloth, air drying, and protection from excessive moisture. Prolonged exposure to saltwater accelerates deterioration; rubber or NATO straps are preferable for intensive marine environments. Natural patina development in tanned leather is desirable and reflects authentic use.
