Strap for SeaQ Date Stainless Steel / Green / Synthetic - Pin

The SeaQ 1-39-11-13-83-08 features a lug width of 20 mm. This measurement is specific to the case geometry and integrated lugs. To verify it precisely, use a digital calliper to measure the space between the spring bars at the base of the case, where the pins seat.

We recommend cemented alligator leather with fine grain or calf leather with vegetable tanning—materials that reflect the Saxonian rigour of the brushed case. For nautical contexts, vulcanised rubber with reinforced canvas keeper ensures grip in salt-water environments and dimensional stability. Avoid overly light-coloured straps: cognac brown, carbon black, or navy blue maintain the tonal equilibrium of the design proposal.

The SeaQ's spring bars are removable via a spring bar tool. Insert the tool near the lug, at the spring bar slot, and press gently towards the case centre: the protruding end allows extraction. Repeat for the opposite side and insert the new strap by aligning one end first, then compressing the spring bar until fully seated.

Yes, any strap with a 20 mm lug width is compatible with the SeaQ 1-39-11-13-83-08. Precise measurement is critical: 20 mm exactly ensures tight fit and stability. Straps of 19 mm or 21 mm introduce unacceptable play. Always verify the specification on the strap's technical sheet before purchase.

A quality leather strap (alligator or vegetable-tanned calf) retains structural and aesthetic integrity for 18–36 months under daily intensive wear, depending on climate and humidity exposure. In arid conditions or with sporadic use, durability extends beyond 3 years. Vulcanised rubber, being more resilient, permits longer service lives (4–5 years). Periodic leather regeneration using neutral balms decelerates accelerated ageing.
