Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-07-83-70?

The lug width is 21 mm. This measurement refers to the internal width of the watch case's lug slots. When purchasing a compatible strap, it must be specifically designed for this width to ensure precise fitment without lateral play.

Which strap type is most suitable for the SeaQ?

The SeaQ accommodates multiple solutions. For formal wear, polished black alligator is classical and refined. For nautical or sporting contexts, FKM rubber offers secure grip and water resistance. Vegetable-tanned calf leather represents an elegant compromise between luxury and functionality, developing an appealing patina over time.

How do I safely change the strap on my SeaQ?

The SeaQ uses straight lugs with spring bars. Obtain a thin spring bar tool or a dedicated watch tool. Insert the tool through the lateral hole of the spring bar to release it, remove the old strap and thread the new one through the lugs. Verify that the spring bar re-engages correctly—it should produce an audible click.

Must an aftermarket SeaQ strap be a specific lug width?

Absolutely. A 21 mm strap is manufactured with precise tolerances to fit correctly through the lugs. Using incorrect widths (20 mm or 22 mm) causes friction, lateral play, or insertion failure. Always verify the technical specification before purchase.

How long does a leather strap last on the SeaQ?

Durability depends on frequency of use, climate, and maintenance. An artisanal alligator strap lasts 3–5 years with daily wear. Vegetable-tanned leather ages more visibly but more charmingly. Rubber endures longer (5–7 years) but loses elasticity under UV exposure. Store the strap in a dry location and apply specialised balms every 12–18 months.
