Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-03-90-35?

The lug width of the SeaQ 1-36-13-03-90-35 is 21 mm, an unconventional specification that provides versatility rarely found in contemporary dive watches. This precise measurement is structural in Saxon design philosophy and ensures perfect fit with carefully selected artisanal straps.

Which strap is most suitable for the Glashütte Original SeaQ in rose gold?

For the rose gold SeaQ, we recommend cognac alligator with fine grain or vegetable-tanned taurillon leather in tobacco tones. Both dialogue harmoniously with rose gold warmth, developing patina over time. For intensive marine use, structured FKM rubber offers performance and aesthetic contrast.

How do I change the strap on a watch with 21 mm lugs?

Position the watch on a soft pad with the dial facing downward. Using a spring bar tool, gently remove the attachment pins from the lugs. Insert the pins into the new strap, ensuring they are aligned perpendicular to the case plane. Apply uniform pressure until the locking click is heard.

Which aftermarket straps are compatible with the Glashütte Original SeaQ?

All straps with 21 mm lug width are compatible with the SeaQ. milanostraps.it offers a selection of artisanal straps in alligator, taurillon, shell cordovan, NATO, and technical rubber, crafted with millimetre precision to guarantee optimal fit and multi-year durability.

How long does a leather strap last on a dive watch?

A premium leather strap, subject to regular maintenance (cleaning with damp cloth, avoiding frequent immersion), maintains structural integrity for 8-12 years. Vegetable tanning ages more rapidly than modern chrome tanning, acquiring distinctive patina. For intensive marine use, we recommend alternating with FKM rubber to extend the life of your leather strap.
