Strap for Seastar 1000 Powermatic 80

The lug width of the Tissot Seastar T066.407.17.057.03 is 20mm. This dimension represents the exact distance between the two lugs on the case and is the fundamental specification for selecting compatible aftermarket straps. Always measure with a digital calliper, perpendicular to the case, between the inner edges of the lugs to obtain the accurate measurement.

The Tissot Seastar T066.407.17.057.03, with its ceramic and steel case, pairs exceptionally well with straps in vegetable-tanned alligator leather, fine-grained calf, or Cordura NATO fabric. Alligator creates the maximum aesthetic contrast and dialogues perfectly with the case's chromatic duality. For actual water use, FKM (Viton) rubber remains the technically superior option.

To change the strap on your Seastar T066.407.17.057.03, you will need a spring bar removal tool. Place the watch on a soft surface to prevent scratches, gently insert the tool into the small lateral hole of the spring, push inward and lift the lug attachment. Repeat on the other side. Install the new 20mm strap by reversing the procedure, ensuring the spring bar clicks correctly into position.

Yes, numerous aftermarket straps are compatible with the Tissot Seastar T066.407.17.057.03 thanks to the standardised 20mm lug width. On milanostraps.it an extensive selection of 20mm straps is available in alligator leather, calf, NATO and technical rubber, all ready for shipment and customisable according to your aesthetic and functional preferences.

The durability of a natural leather strap on a sports watch like the Seastar depends on usage intensity and climatic conditions. If exposed to frequent moisture or immersion, natural leather deteriorates more rapidly. A quality alligator strap can last 3-5 years with regular maintenance and water protection. For intensive maritime use, we recommend alternating with an FKM rubber strap to extend leather life.
