Strap for Seastar 1000 36 Quartz Stainless Steel / Black / Bracelet

The lug width of the Tissot Seastar T120.210.11.051.00 is 18mm. This measurement represents the distance between the spring bar pins located at 12 and 6 o'clock on the case. This parameter determines compatibility with any aftermarket strap: an 18mm strap will fit perfectly without requiring adaptors or modifications.

The choice depends on intended use. For daily elegance, we recommend vegetable-tanned Tuscan leather with natural patina that evolves over time. If the watch is destined for diving or aggressive environments (chlorine, salt), FKM rubber offers complete waterproofing and zero maintenance. Alligator represents the ideal compromise between luxury and durability. NATO fabric straps are perfect for those seeking practicality and immediate sporty character.

The process requires a simple tool (spring bar removal tool) or a small flat screwdriver. Locate the elastic pins (spring bars) connecting the strap to the case at 12 and 6 o'clock. Push gently inward to disengage them, then slide off the old strap. Align the new strap with the lug holes and reinsert the pins until they click into position. The procedure takes less than a minute for experienced users.

Any strap with 18mm lug width is compatible. Always verify this measurement with the manufacturer. Milano Straps offers a complete collection of 18mm straps: vegetable leather, alligator, shell cordovan, FKM rubber, NATO fabric. All are tested for mechanical and aesthetic compatibility with the Seastar.

Durability depends on frequency of use, sun exposure, and humidity. A quality vegetable-tanned leather strap, used daily and subject to basic maintenance (occasional cleaning, annual oiling), has an average lifespan of 3-5 years before showing significant wear signs. Alligator and shell cordovan, thanks to their superior density, can exceed 5-7 years. FKM rubber maintains structural integrity for 7-10 years without chemical deterioration.
