Strap for Chrono XL Black PVD / Black

The lug width of the Tissot Seastar 1000 Powermatic 80 XL is precisely 22mm. This dimension is standardised by Tissot for this model family and is essential for purchasing compatible aftermarket straps. To verify it with accuracy, use a digital calliper positioned perpendicularly to the case, measuring from the inner lug slot to the inner lug slot of the spring bar. Avoid measuring from external edge to external edge, a common error leading to incorrect strap purchases.

The choice depends on intended usage and desired aesthetic profile. For formal contexts, a black or chocolate alligator 22mm elevates the watch whilst preserving its aquatic soul. For daily wear and versatility, a vegetable-tanned calfskin develops patina evolution parallel to the steel case. A cotton-nylon NATO ensures maximum utility and chromatic flexibility. For marine environments or high humidity, a FKM rubber strap represents the technical choice: indestructible and thermally stable.

Strap change requires a simple tool: a spring bar tool or small watchmaker's hammer. Position the watch on a soft surface with the lug side facing upwards. Insert the bifid tip of the spring bar tool under the spring bar and apply gentle downward pressure to disengage the pin. Repeat on the opposite side. Remove the old strap and insert the new one aligning the holes with the pins, then lower the bars until fully seated. Verify that both sides are completely secured before wearing the watch.

Yes, absolutely. Any strap with 22mm lug width and holes compatible with the internal width of the lugs (standard for this size) may be mounted on your Seastar 1000 XL without any issue. Artisanal straps, quality aftermarket options, or straps from brands specialising in premium leather and textiles adapt perfectly. We recommend choosing suppliers who guarantee precision in eyelet workmanship and measurement to ensure precise fitting without excessive play.

The lifespan of a leather strap depends on construction quality, tanning method, usage and maintenance. A vegetable-tanned calfskin of good quality lasts approximately 3–5 years of daily wear before requiring replacement due to structural degradation. Industrial chrome tanning degrades more rapidly, within 2–3 years. Frequent exposure to moisture and perspiration shortens these timescales. Periodically, you may apply protective balms based on beeswax to extend operational life. A FKM rubber strap, conversely, maintains elasticity and resistance for 5–8 years of intensive use.
