Strap for Seastar 1000 36 Quartz Stainless Steel - Yellow Gold / Black / Bracelet

The lug width of the Tissot Seastar T120.210.22.051.00 is 18 millimetres. This measurement was calibrated to maintain visual balance between the 36-millimetre case diameter and the overall proportions of the watch. When purchasing an aftermarket strap, it is important to measure your lugs accurately using a digital calliper or cloth tape to avoid undesired tension on the case.

For the T120.210.22.051.00, alligator leather with vegetable tanning represents the option that best enhances the model's character. Shell cordovan is advisable for superior durability and a patina that deepens over time. For formal contexts, English calf leather offers an excellent compromise between softness and resistance. If you intend to exploit the model's underwater capabilities, vulcanised rubber is the only rational choice, as it maintains flexibility even in salt water.

Changing the strap requires small specific tools: a small spring bar remover or dedicated pin extractor. Insert the tool into the appropriate hole of the lug, applying gentle pressure to release the first spring bar, then carefully pull away the old strap. Reinsert the new strap by aligning the holes with the lugs and verify that the spring bars click correctly into place. If you feel uncertain, a professional watchmaker can complete the operation in just a few minutes.

Any strap with an 18-millimetre lug width is compatible with the T120.210.22.051.00. This includes leather straps (alligator, calf, shell cordovan), military NATO, vulcanised rubber, canvas, cotton sateen and even stainless steel. Compatibility depends exclusively on the lug width; material, colour and style are entirely free choices according to your personal preference.

The longevity of a strap depends on the material and intensity of use. Quality alligator with vegetable tanning can last 5-7 years with ordinary maintenance (regular cleaning, protection from excessive moisture). Shell cordovan, being denser, can reach even 10 years. Traditional calf leather typically lasts 3-5 years. Vulcanised rubber offers 4-6 years of resistance. Protecting the strap from direct sunlight, stagnant water and aggressive detergents significantly extends its useful life.
