FAQ

What is the lug width of the Nomos Glashütte Club 790?

The Nomos Glashütte Club 790 features a lug width of 20mm, a specific dimension that requires straps constructed to this precise specification. This intermediate size was chosen by Glashütte to maintain perfect optical proportions between the 40mm case and the wrist suspension. Standard 18mm or 22mm straps are not compatible with this model.

Which strap is best suited for the Nomos Glashütte Club 790?

For the Club 790, we recommend a vegetable-tanned leather strap (cordovan or black calf), which reflects the German aesthetic rigour of the timepiece. Vegetable tanning provides the structural integrity needed to support the 20mm lugs without sagging. Alternatively, for nautical or sporting use, a cotton-linen NATO maintains elegance and practicality, whilst FKM rubber ensures maximum environmental resistance.

How do you change the strap on a Nomos Glashütte Club 790?

The Club 790 strap is changed using a spring bar remover tool to extract the terminals (lugs) from the case shoulders. Gently release the spring at the base of each terminal, remove the old strap, and insert the new one, aligning the terminals to the 20mm seats. This operation requires precision to avoid damaging the spring rings: if uncertain, consult a professional watchmaker.

Which aftermarket straps are compatible with the Nomos Glashütte Club 790?

The Nomos Club 790 requires straps with a specific 20mm lug width. Milano Straps offers a comprehensive selection of artisanal straps in leather (alligator, cordovan, calf), NATO, and rubber, all dimensioned precisely to 20mm and ready for dispatch. The rarity of this width makes it imperative to always verify compatibility before purchase.

How long does a leather strap last on a Nomos Glashütte Club 790?

A quality leather strap (cordovan or vegetable-tanned calf) lasts an average of 4-6 years with daily wear, developing a patina that characterises it visually over time. Longevity depends on exposure to moisture, perspiration, and climatic variation. Aniline leather straps tend to lose brilliance sooner, whilst FKM rubber guarantees 8-10 years of unaltered resistance, without aesthetic ageing but with less tactile personality.
