Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-04-91-33?

The lug width of the SeaQ 1-36-13-04-91-33 is 21 mm, measured centre-to-centre between the spring bar attachments on the case lugs. A 21 mm strap ensures correct seating at the lugs without play or excessive compression.

What is the best strap for the Glashütte Original SeaQ?

For this 43.20 mm case in rose gold and stainless steel, we recommend natural alligator or shell cordovan in vegetable tanning. Alligator offers consistent colour and superior durability; cordovan develops aesthetic patina over time. For intensive marine environments, high-quality FKM rubber remains the most versatile choice.

How do I change the strap on the SeaQ 1-36-13-04-91-33?

Strap replacement requires a spring bar tool to remove the attachment pins from the case lugs. Gently press the pin from the opposite side, free the end from the hole, remove the old strap, and insert the new one by aligning the holes with the spring bar attachments. Avoid improvised tools that may scratch the gold case.

Is the Glashütte SeaQ strap compatible with other watches?

The 21 mm strap from the SeaQ is compatible with any watch featuring an identical 21 mm lug width. However, given the substantial case diameter (43.20 mm), we recommend verifying visual harmony with the other watch's case. Not all watches in this category proportion straps identically.

How long does a leather strap last on the SeaQ?

A high-quality artisanal alligator or cordovan strap, with regular wear, typically lasts 5–7 years before requiring restoration or replacement. Longevity depends on sun exposure, frequent water contact, and wear frequency. Vegetable tanning ensures superior durability compared to synthetic tanning, especially if the strap receives periodic water-repellent maintenance.
