Strap for Seastar 1000 Quartz Chronograph Stainless Steel / Grey / Bracelet

The lug width of the Tissot Seastar T120.217.11.061.00 is 20mm. This measurement is taken between the lateral lugs protruding from the case, from outer edge to outer edge. A 20mm lug width is a classic standard for medium-format sports watches and provides access to a broad range of artisanal straps, from premium leathers to technical fabrics.

For the Seastar T120.217.11.061.00, we recommend an alligator strap via vegetable tanning for elevated formality, satin calf for modernity, or vulcanised rubber to accentuate the sports heritage. A NATO strap in high-density nylon is ideal for extensive use and humid environments. Your choice depends on wearing context and personal aesthetic preference.

Strap replacement is straightforward: obtain a spring bar tool in stainless steel. Position the tool under the lateral lugs from the case back side, push inward to release the spring bar, and remove the old strap. Align the new strap with the case lugs, insert the bars, and verify secure locking. No specialist tools are required.

Yes, all artisanal straps from milanostraps in 20mm lug width are compatible with the Tissot Seastar T120.217.11.061.00. We offer leather, alligator, shell cordovan, NATO, and rubber options with customisation available. Always verify the lug width marking before purchase to confirm compatibility with your specific model.

Durability depends on material and usage. An alligator strap via vegetable tanning may last 10–15 years with regular care. Satin calf lasts 5–8 years. Vulcanised rubber straps last 8–12 years. Exposure to direct sunlight, humidity, and perspiration accelerates ageing. Regular maintenance—cleaning and conditioning—significantly extends strap lifespan.
