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

The lug width of the SeaQ 1-39-11-10-70-08 is 20 millimetres. This measurement defines the distance between the inner edges of the case lugs. It is essential to verify this specification before ordering a compatible strap, as variations of even 1mm can compromise fit and visual stability.

For the two-tone yellow gold and stainless steel variant, we recommend alligator leather in dark brown or cognac with vegetable tanning, which develops patina over time. Alternatively, a dark navy NATO strap maintains sporting balance without competing with the case's material complexity. Grey FKM rubber remains the most neutral and functionally appropriate option for aquatic contexts.

The SeaQ features standard lugs with lateral pass-holes. Using a spring bar tool, position the tips into the lateral holes and apply calibrated pressure to extract the pin securing the strap. Subsequently, remove the used strap and insert the new one, then reinsert the pin. The operation requires 2-3 minutes; avoid excessive force to prevent damage to the yellow gold lugs.

Yes, any strap with a 20mm lug width is compatible. However, construction quality significantly influences perception: with a two-tone case in gold and steel, we recommend straps crafted from premium leather (vegetable-tanned, shell cordovan) or robust textiles (NATO in cotton-polyester blend). Avoid economical synthetic leather straps, which would emphasise the disparity relative to the SeaQ's inherent luxury.

A properly maintained vegetable-tanned leather strap—dried after prolonged water contact, protected from direct sunlight—develops visible patina after 12-18 months and maintains functionality for 3-5 years before requiring replacement. The SeaQ, engineered for 300-metre dives, suggests seasonal alternation between leather and FKM rubber straps to extend overall durability and vary aesthetic profile.
