Strap for Seastar 1000 Quartz GMT 40 Stainless Steel - Yellow Gold / Black / Bracelet

The lug width of the Tissot Seastar T120.852.22.051.00 is exactly 20 millimetres. This measurement must be respected with precision: a 18mm or 22mm strap will not fit correctly. Verify with a digital calliper by measuring the internal space between the upper and lower lugs of the case.

For the Seastar we recommend three primary options. An alligator strap with vegetable tanning for elegance and natural patina development over time. A vegetable-tanned calf leather for the balance between practicality and aesthetic refinement, with regular grain. A rubber FKM strap or Rip-Stop cotton NATO for intense aquatic activities, where wet grip is essential.

The procedure requires a spring bar remover tool. Position the watch with the lug facing you, insert the flat tip of the remover under the internal spring of the lug, compress lightly until the spring disengages, then extract the bar. Repeat on the opposite side. Proceed in reverse to mount the new strap. If you lack experience, consult a watchmaker or our laboratory.

Yes, completely. The Seastar T120.852.22.051.00 does not use proprietary or rare lug sizes. Any quality strap with a 20mm lug width fits perfectly. Leather, rubber, NATO, shell cordovan: all categories are compatible. Explore our 20mm strap collection to discover over fifty variations.

A high-quality leather strap (vegetable-tanned alligator, vegetable-tanned calf) lasts 3-5 years with moderate daily use, depending on ambient humidity and frequency of water contact. Vegetable tanning develops natural patina that extends aesthetic credibility even as elasticity begins to diminish. A vulcanised rubber or NATO strap has greater longevity (7-10 years) as it is not subject to leather dehydration.
