Strap for Club Sport Green / DXM

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.

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.

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.

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.

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.
