Strap for Seastar 1000 Powermatic 80 43 Rose Gold / Black / Rubber

The lug width of the Tissot Seastar T120.407.37.051.01 is 21mm. This measurement represents the distance between the two attachment points (lugs) on the case. It is essential to verify this specification when purchasing an aftermarket strap to ensure perfect compatibility with the watch.

The ideal strap depends on use and aesthetic preferences. For formal elegance: black alligator with steel deployante. For everyday versatility: vegetable-tanned calf in neutral or tan tones. For marine and sports environments: NATO in grey Cordura or elastomeric rubber. All must respect the 21mm lug width.

The change is performed by removing the lug pins (spring bars) using a dedicated spring bar tool. Gently lift the pin from one side, remove the old strap, then insert the new strap into the attachments and reposition the pin. Verify that the pin is correctly inserted on both sides before wearing the watch.

Any strap with a 21mm lug width is compatible with this model. Options are available in alligator, calf, shell cordovan, vegetable-tanned leather, canvas NATO, Croslite rubber and other elastomers. Ensure the lug width is exactly 21mm and that the strap thickness does not exceed the insertion space on the case.

Durability varies based on material and usage. A vegetable-tanned calf strap typically lasts 3-5 years with daily wear. Alligator, due to harder structure, can last 5-7 years. Factors affecting longevity: sun exposure, humidity, frequency of use. Regular maintenance (cleaning, conditioning with natural waxes) significantly extends strap life.
