Frequently asked questions

What is the lug width of the Nomos Glashütte Club 737.S5?

The Nomos Glashütte Club 737.S5 features a lug width of 20.00 mm. This dimension is precise and verifiable by placing a digital caliper between the pins that connect the case to the lugs. It is essential to verify this measurement before ordering an aftermarket strap, as dimensional compatibility determines correct fit on the attachment pins.

Which strap is most suitable for the Nomos Club 737.S5?

For aesthetic coherence with the 737.S5's Bauhaus design philosophy, we recommend straps in alligator (Mississipi or caiman with traditional tannage), vegetable-tanned calf leather (black, grey talpa, or cognac), or NATO fabric (navy blue, military green) paired with a brushed steel buckle. Avoid inexpensive synthetic materials: the Club deserves construction quality that does not betray its design at the wrist.

How do you replace the strap on a Nomos Club 737.S5?

Strap replacement is a simple but delicate procedure. Position the watch on a soft pad, locate the attachment pins at 9 and 3 o'clock (hidden within the case lugs), use a spring bar remover to gently lift the pin and slide out the old strap. Insert the new 20 mm strap, aligning the holes, and press until the pin clicks into place. Avoid using abrasive tools on the case during the operation.

Is a quality aftermarket strap compatible with the Nomos Club 737.S5?

Yes, provided the lug width is exactly 20 mm and the attachment pins have standard diameter (approximately 1.4 mm). Artisanal straps produced by specialist ateliers offer superior construction quality to OEM straps: noble aged leather, hand-finished details, greater customisation options. Always verify technical specifications before purchase.

How long does a leather strap last on the Nomos Club 737.S5?

Durability depends on frequency of use, climatic conditions, and material type. A quality alligator or vegetable-tanned calf strap can exceed 5–7 years of daily wear, developing a noble patina. Rubber offers superior durability (8–10 years) without aesthetic evolution. NATO fabric resists 6–10 years provided the buckle remains in steel. Leather ageing is a desirable characteristic on the Club 737.S5, as is the evolution of patina.
