Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-37-23-02-81-08?

The lug width of the SeaQ is 21 mm. This measurement is taken from the inner edge of one lug hole to the inner edge of the opposite lug hole. Verifying this measurement before purchasing an aftermarket strap ensures correct compatibility and proper installation without lateral play.

What is the best strap for the Glashütte Original SeaQ?

The optimal strap depends on intended usage. For formal applications, dark brown or black alligator with vegetable tanning is recommended. For marine environments and sports contexts, a high-density polyamide NATO strap or FKM rubber strap ensures chemical resistance and practicality for rapid deployment. Red burgundy shell cordovan represents a sophisticated compromise between aesthetics and functionality.

How do you change the strap of a Glashütte Original SeaQ 1-37-23-02-81-08?

Strap replacement is accomplished through the spring bars located at the lug positions. Using a dedicated spring bar tool, compress the spring, extract the pin, and remove the previous strap. Insert the new strap (21 mm width), verify that the spring engages correctly within the lug holes, and confirm symmetry and absence of movement. For optimal results, professional installation at Atelier Casati Milano is recommended.

Which aftermarket straps are compatible with the SeaQ?

All straps with 21 mm lug width are compatible with the SeaQ 1-37-23-02-81-08. MilanoStraps offers an extensive selection of artisanal leather straps in alligator, calf, shell cordovan, NATO fabrics, and FKM rubber, all tested to ensure absence of lateral play and correct adhesion to the case profile.

What is the typical lifespan of a leather strap for the SeaQ?

A high-quality leather strap (alligator, shell cordovan) with appropriate care typically lasts 18–36 months. Durability depends on frequency of use, moisture exposure, and maintenance practices. An FKM rubber strap offers superior longevity (3–5 years) but requires periodic cleaning. NATO straps, manufactured from polyamide, typically last 24–48 months before displaying significant wear.
