The Heritage

The Nomos Glashütte Club 773.S1 is a contemporary statement of German watchmaking philosophy, embodying Bauhaus principles and Saxon rigor. It features a 40mm stainless steel case with a 20mm lug width, housing the manual DUW 5001 caliber visible through an anti-reflective sapphire crystal. The white dial with applied baguette indices displays hours, minutes, and small seconds, while the brushed steel case and temperature-compensated movement reflect Glashütte's commitment to essentialist design without decorative excess.

FAQ

What is the lug width of the Nomos Glashütte Club 773.S1?

The lug width of the Nomos Glashütte Club 773.S1 is 20mm. This precisely standardised measurement corresponds to the distance between the inner edges of both lugs where the strap attaches to the case. It is a critical parameter for universal compatibility with artisanal straps.

What is the best strap for the Nomos Glashütte Club 773.S1?

The choice depends on intended use. For formal occasions, vegetable-tanned alligator in cognac or dark brown offers evolving patina and uncompromising elegance. For conscious daily wear, vegetable-tanned calf in havana ensures practicality and aesthetic development over time. For robust casual or sport contexts, a grey or black cordura NATO echoes the Bauhaus colour palette. Anthracite rubber, finally, transforms the 773.S1 into pure wrist instrumentation.

How do I change the strap on the Nomos Glashütte Club 773.S1?

The strap attaches to the lugs via spring bars. Using a spring bar tool or a flat knife tip, gently press inward on one of the two retaining spring poles: this liberates the strap. Repeat on the opposite side. For installation, insert one end of the retaining spring into the lug first, then press the other end until it clicks.

Is an aftermarket 20mm strap compatible with the Club 773.S1?

Yes, absolutely. The standardisation of the 20mm lug width makes the 773.S1 universally compatible with all artisanal straps of the same width, regardless of brand or material. The only care required is to verify that the strap has a bar diameter suited to the case (typically 1.8-2.2mm), a specification almost invariably respected in quality straps.

How long does a leather strap last?

A vegetable-tanned leather strap, with ordinary maintenance (occasional cleaning, protection from excessive moisture), maintains functionality and aesthetic for 5-8 years. The initial thickness of 1.8-2.2mm gradually diminishes; when material fatigue becomes evident (edge delamination, loss of structure), replacement is timely. Alligator, with denser texture, may last even 10 years. Ageing itself is part of the beauty: patina is not decay, but evolution.
