Strap for Chrono XL Classic Stainless Steel / Blue / Bracelet

The Tissot Seastar 1000 Chronograph XL T116.617.11.047.01 features a lug width of 22 millimetres. This width is specific to large-diameter cases (45mm) and is essential for maintaining the correct visual proportions between the case mass and strap section. Measurement must be performed precisely using a calliper, positioning the calliper tip perpendicularly to the case plane, between the two lug attachment points.

Strap selection depends on the intended use. For dry environments and formal contexts, an alligator or vegetable-tanned calf leather strap enhances the chronograph's elegance. For authentic sports use with frequent water contact, synthetic rubber or technical NATO straps offer superior resistance and simplified maintenance. A regenerated-fibre NATO strap represents the ideal compromise between aesthetic versatility and everyday practicality.

Strap replacement requires a specific tool: the spring bar removal tool. Position the watch on a soft surface to prevent case scratching. Insert the tool tip into the hole beneath the lug, pushing downward to release the internal spring. Once released, the strap slides away. For the new strap, insert the spring bar (the metal spring found at the strap ends) into the lug holes, pushing until it clicks into position with a subtle snap. Verify that the strap is perfectly centred relative to the case.

The Tissot Seastar 1000 Chronograph XL is compatible with any standard strap featuring a 22mm lug width. Milano Straps offers a specialised collection including alligator, vegetable-tanned calf, sustainable NATO fabrics and pressed synthetic rubber straps. All these straps maintain the technical characteristics of the original Tissot model, guaranteeing water resistance and functionality without compromise. Online personalisation allows selection of finishes, colours and construction details (stitching, buckle, keeper type) according to individual preferences.

Leather strap durability depends on tanning quality and frequency of use. An alligator or vegetable-tanned calf strap, if subjected to periodic maintenance (cleaning with damp cloth, application of neutral grease), maintains structural integrity for 5-7 years of daily use under normal conditions. Exposure to constant humidity, chlorine, saltwater or prolonged sunlight accelerates deterioration. Synthetic rubber straps offer superior durability, up to 10 years even under critical conditions, whilst regenerated-fibre NATO straps maintain elasticity and integrity for 6-8 years with intensive use.
