Strap for Seastar 1000 Automatic Chronograph Orange

The lug width of the Tissot Seastar T066.427.17.057.01 is 23mm. It is measured internally between the two lugs of the case where the strap sits. This is an unconventional standard that requires straps built to precise specifications to ensure correct fit without improvised adjustments.

For the Seastar T066.427.17.057.01, we recommend alligator straps in toasted brown or black for formal elegance, vegetable-tanned calf in cognac tones for natural patina, heavy-weight NATO canvas for sporty versatility, or FKM rubber for diving and marine environments. Your choice depends on primary usage and context: formal, sport, or underwater.

The strap is changed using a spring bar removal tool. Position the forked end under the pin connecting the strap to the lug, push downward to compress the internal spring, then slide the pin sideways. Reverse the procedure to install the new strap. For 48mm watches, we recommend professional assistance to avoid scratching the case.

Any strap built for 23mm lug width is compatible with the Seastar T066.427.17.057.01. Milano Straps artisanal straps in 23mm size guarantee superior quality in alligator, calf, NATO and rubber. Always verify that the pins are standard diameter (1.8mm) for smooth insertion.

A high-quality leather strap—alligator or calf—typically lasts 3-5 years with moderate daily wear. In very humid environments or with frequent salt water exposure, longevity may reduce to 18-24 months. To maximise lifespan, alternate the strap with rubber variants during summer or diving, and allow complete drying after every water contact. Regular maintenance with natural balms extends useful life.
