Nomos Glashütte
Club 733.S6— lug 20mm

The lug width of the Nomos Glashütte Club 733.S6 is 20 mm. This measurement represents the distance between the two lugs of the case and determines compatibility with aftermarket straps. Nomos manufacturing tolerances ensure uniformity at 20.0 mm without deviation, allowing the use of any standard strap of this width.

Strap choice depends on usage context. For formal elegance, we recommend vegetable-tanned leather or alligator. For daily versatility, shell cordovan offers superior structural durability. For sporting or casual activities, a nylon NATO or FKM rubber strap keeps the piece practical. All these materials are available in 20 mm width through Casati Milano and our catalogues.

Strap replacement is performed via the lug pins situated at the case extremities. Using a professional spring bar tool, gently compress the pin to extract it from the lugs, remove the old strap, and insert the new one ensuring the pins seat perfectly in the new lugs. We recommend performing this operation on a soft surface to avoid case scratching.

Yes, the Club 733.S6 is fully compatible with aftermarket straps of 20 mm lug width. Always verify lug width (20 mm) before purchase. We recommend manufacturing-quality straps to preserve the aesthetic and structural integrity of the watch, particularly leather straps with vegetable tanning or shell cordovan.

A manufacturing-quality leather strap, used under normal conditions (no water immersion), maintains structural integrity for 3–5 years. Durability increases with thicker leathers such as shell cordovan (5–7 years), whilst anilinated calf may show aesthetic wear more quickly but remains functional. Prolonged exposure to sunlight, humidity, or chlorine significantly shortens strap lifespan; rotating between multiple straps is recommended to extend longevity.
