Frequently asked questions

What is the lug width of the Tissot Seastar T066.427.11.057.00?

The lug width of the Tissot Seastar T066.427.11.057.00 is 23mm, a non-standard dimension that requires specifically designed straps. This measurement, taken between the inner edges of the case lugs, is not commonly found in standard catalogues and demands careful selection from specialised suppliers.

Which strap is best suited for the Seastar T066.427.11.057.00?

For the Seastar T066.427.11.057.00, an alligator strap with vegetable tanning is recommended, as it accentuates the contrast between the leather's texture and the brushed stainless steel case. Alternatively, a NATO strap in nylon or canvas offers summer practicality, whilst elastomers provide resistance in humid or saline environments.

How do you change the strap on the Tissot Seastar T066.427.11.057.00?

Strap replacement requires extraction of the spring bars connecting the strap to the lugs. Use a dedicated tool or small flathead screwdriver, gently inserting it between the bar and case, then lever downward. Remove the bar completely, take off the old strap, and insert the new one, ensuring the spring bar is fully secured in both lug holes.

Which aftermarket straps are compatible with the Seastar T066.427.11.057.00?

All straps with a 23mm lug width are compatible, regardless of material: leather (calf, alligator, shell cordovan), textiles (NATO, canvas), elastomers and rubbers. Compatibility is guaranteed by lug width; material choice depends on your intended use and aesthetic preferences.

How long does a leather strap last on the Seastar T066.427.11.057.00?

A quality leather strap with vegetable tanning typically lasts 3-5 years with daily wear. Longevity depends on weather exposure, humidity and care. Alligator straps tend to last longer due to fibre density; calf requires more frequent maintenance. Avoid prolonged exposure to salt water and periodically apply a protective balm.
