Strap for Seastar 1000 Automatic Chronograph Blue

The lug width of the Tissot Seastar T066.427.11.047.00 is 23mm. This is a specific size that requires custom-designed straps and is not found in standard watch strap catalogues.

For the 48mm Seastar, we recommend a strap in alligator or vegetable-tanned calf leather with robust thickness to complement the case mass. Alternatively, vulcanised rubber for a sporty profile. Choice depends on primary use: formal elegance or aquatic durability.

The strap is replaced via the side lugs of the case. Using a spring bar tool or small screwdriver, remove the spring pin holding the old strap. Align the new strap with the lug and reinsert the pin until it clicks into position. Avoid excessive pressure that could damage the lugs.

Yes, quality aftermarket straps are available for the 23mm lug width from specialists such as Milano Straps. They are constructed to the same quality standards and materials as original straps, often with superior personalisation and artisanal options.

A quality artisanal vegetable-tanned leather strap lasts 3–5 years under normal use conditions. Longevity depends on frequency of wear, ambient humidity and care. Vegetable-tanned leather develops patina over time, enriching aesthetic appearance. Synthetic rubber and NATO straps offer greater durability (5–8 years) with minimal aesthetic variation.
