Strap for Club Sport Neomatik Worldtimer Magma

The lug width of the Nomos Glashütte Club 790.S5 is 20mm. This dimension is critical for strap compatibility: before any purchase, verify the value by measuring between the internal attachment points of the case with a digital calliper.

For the Club 790.S5, we recommend vegetable-tanned alligator for formality, shell cordovan for deep patina development, calf leather for chromatic versatility, or woven NATO for contemporary practicality. Your choice depends on usage and context: the minimalist design of the watch pairs naturally with restrained straps.

The strap is changed using a standard spring bar removal tool. Place the watch on a soft surface, access the side attachment holes, gently compress the spring bar with the tool until the pin releases, and slide the old strap out. Insert the new strap and reposition the spring bars in the same manner. This is a straightforward and fully reversible operation.

Yes, any 20mm strap is compatible with all watches featuring a 20mm lug width. Always verify with a calliper before purchase: even a minor variation of 0.5mm can compromise perfect fit.

A quality leather strap (alligator, calf or shell cordovan) with vegetable tanning lasts on average 3–5 years with daily wear, developing an appreciable natural patina. Longevity depends on intensity of use, ambient humidity, and maintenance: periodic gentle cleaning and protection from salt water extend its useful life.
