Strap for SeaQ Chronograph Stainless Steel / Blue / Rubber - Pin

The lug width (or lug-to-lug distance) of the SeaQ is precisely 21.00 mm. This dimension is determined by the 43.20 mm case geometry and integrated lugs. To verify the lug width, measure the internal distance between spring bars using a digital calliper; the value should fall between 20.9 and 21.1 mm to ensure correct fit and aesthetic positioning on the case.

Strap selection depends on use case and aesthetic preference. For formal wear, we recommend vegetable-tanned alligator leather, which develops natural patina over time. For daily versatility, a NATO strap in high-density polyamide offers robustness and visual clarity. For aquatic environments, a technical rubber strap with micro-texture provides exceptional grip and ease of maintenance.

The SeaQ uses standard 21 mm spring bars. To replace the strap, use a spring bar removal tool: insert the flat blade into the gap between lug and spring bar, then gently extract the bar downward. Remove the old strap and insert the spring bars into the new one, pushing until they lock. Never force the bar; controlled pressure is sufficient to ensure secure positioning.

Yes, any strap with a 21 mm lug width is compatible with the SeaQ. MilanoStraps.it offers a specialised selection of leather straps (alligator, calf, shell cordovan), NATO, and technical rubber, all tested for precise fit and artisanal construction quality. Always verify that the strap width is exactly 21 mm before purchase.

Leather strap durability depends on tanning method, usage, and maintenance. A high-quality vegetable-tanned calf strap lasts 3–5 years under normal conditions; alligator may last 5–7 years due to more fibrous structure. Exposure to moisture, heat, and perspiration accelerates wear. To extend strap lifespan, avoid prolonged immersion (despite the SeaQ's water resistance), apply conditioner every 6–12 months, and store in dry environments.
