Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-01-80-33?

The lug width of the Glashütte Original SeaQ 1-36-13-01-80-33 is 21 mm. This measurement represents the internal distance between the two case attachment pins and corresponds to the inner diameter of the strap required for this model.

What is the best strap for the Glashütte Original SeaQ 1-36-13-01-80-33?

The best strap depends on your usage: for formal elegance we recommend natural alligator with vegetable tanning and waxed patina; for everyday versatility a structured calf leather with vegetable tanning; for water-based activities a polyamide NATO strap with leather pass-through or an FKM rubber strap with stainless steel deployant.

How do I change the strap on my SeaQ 1-36-13-01-80-33?

To change the strap: 1) Position the watch face-down on a soft surface; 2) Use a spring bar removal tool or small flat screwdriver to gently push the pin from the rear side; 3) The pin will come out completely, allowing strap removal; 4) Insert the new strap, aligning it with the holes, and push the pin until fully secured, verifying it is firmly attached on both sides.

Can I use an aftermarket compatible strap with my SeaQ?

Yes, the SeaQ 1-36-13-01-80-33 is fully compatible with quality aftermarket straps, provided they feature a 21 mm lug width. We recommend straps with a minimum thickness of 2.2 mm to maintain original aesthetic proportions and ensure durability over time.

How long does a leather strap last on the Glashütte Original SeaQ?

The lifespan of a leather strap depends on usage and tanning method: with vegetable tanning and moderate use (not daily water exposure), average durability is 3-5 years. Frequent exposure to salt water or chlorine reduces service life to 18-24 months, making NATO or FKM rubber straps more practical for professional use.
