The strap width is 21 mm, proportioned to match the substantial case architecture typical of authentic divers.

Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-01-80-34?

The lug width of the SeaQ 1-36-13-01-80-34 is 21 mm. This measurement represents the distance between the two attachment points of the strap on the case and must be observed with precision to ensure a correct fit without lateral play. By measuring the original strap, you will find that the lug holes are exactly 21 mm apart.

Which strap is best suited for the Glashütte Original SeaQ 1-36-13-01-80-34?

For the SeaQ 1-36-13-01-80-34, we recommend high-quality alligator leather with vegetable tanning and pronounced vertical grain to enhance the sophistication of the satin-finished case. Alternatively, aged calfskin in brown or tobacco tones ensures chromatic versatility, whilst a NATO strap in satin cotton represents the ideal solution for intensive marine use. For sportive-elegant finishing, shell cordovan in deep mahogany creates lasting visual harmony.

How do you change the strap on the Glashütte Original SeaQ 1-36-13-01-80-34?

The strap is changed by removing the spring bars connecting the strap to the case lugs. Position the watch on a stable surface and use a dedicated tool or small lever to compress the internal spring of the bar, then remove the old strap. Insert the new strap by aligning it with the lugs, then reinsert the spring bars, ensuring they click correctly into position. This operation requires precision to avoid damaging the case.

Is an aftermarket strap compatible with the SeaQ 1-36-13-01-80-34?

Yes, any aftermarket strap with a 21 mm lug width is compatible with the SeaQ 1-36-13-01-80-34. It is essential to verify that the lug width is exactly 21 mm and that the spring bars used are suitable for the case hole (standard diameter 1.8-2.0 mm). A bespoke artisanal strap guarantees superior construction quality and materials compared to standard industrial solutions.

How long does a leather strap last on the Glashütte Original SeaQ 1-36-13-01-80-34?

The lifespan of a leather strap depends on the tanning method, usage and maintenance. A high-quality alligator or shell cordovan strap with vegetable tanning can last 5-7 years with regular care, if not continuously exposed to salt water. Calfskin tends to last slightly less, approximately 4-5 years. A rubber or NATO strap guarantees decade-long durability if subjected to periodic maintenance. Prolonged exposure to salt water or perspiration reduces longevity; we recommend alternating straps during the summer season.
