Strap for Seastar 1000 Powermatic 80 40 Stainless Steel / Blue / Bracelet

The lug width of the Tissot Seastar T120.807.11.091.00 is 20mm. This measurement represents the internal space between the two metal lugs of the case where the strap is attached. It is crucial to measure this correctly before purchasing an aftermarket strap to ensure compatibility and proper fit without unwanted slack.

The choice depends on your use case and personal preference. For formal occasions, we recommend alligator or vegetable-tanned leather in brown or cognac tones. For daily and sporty use, hammer-grained leather or FKM rubber offer superior durability. A canvas NATO strap maintains technical character with versatility. Shell cordovan is ideal if you desire a natural patina that evolves over time.

To change the strap, remove the two spring bars that attach the current strap to the case lugs. Use a dedicated spring bar tool or a small lever to carefully pry them out. Extract the old strap, insert the new one (ensuring 20mm lug width), and reinsert the spring bars until they click securely into place. If inexperienced, consult a specialised watchmaker.

Yes, absolutely. A high-quality artisanal aftermarket strap is not only compatible but recommended to personalise your Seastar and preserve the original strap from wear. The essential requirement is selecting a 20mm lug-width strap and opting for superior materials: vegetable-tanned leather, alligator, or shell cordovan. A well-crafted strap amplifies the watch's aesthetic identity.

Durability depends on material and usage patterns. Quality vegetable-tanned leather lasts 3-5 years with moderate daily wear. Alligator, more robust, reaches 5-7 years. Shell cordovan can last beyond 10 years while developing an admirable patina. Critical factors include humidity and perspiration exposure, wearing frequency, and maintenance (periodic cleaning, conditioning). A well-crafted strap ages elegantly rather than degrading.
