Strap for Club Campus 36 Blue Purple

The lug width of the Nomos Glashütte Club 713 is 18 millimetres. This dimension requires aftermarket straps specifically sized to 18mm; it is not compatible with larger standards such as 20 or 22mm. The 18mm represents an elegant compromise between the reduced proportions of the 36mm case and the practical availability of aftermarket straps.

For the Club 713, the ideal material depends on usage and personal preference. Cognac-coloured shell cordovan leather creates an elegant contrast with the steel case; vegetable-tanned calf leather offers softness and textural character; grey NATO fabric complements the watch's minimalism; FKM rubber is the most practical choice for summer wear. What matters is that the strap is proportioned to the 18mm lug width and the watch's slender profile.

To change the strap on a Nomos Club 713, you must remove the spring bars that secure the strap to the lugs. Use a dedicated tool (spring bar tool) or a fine needle to push the bar laterally, lift one end of the strap, and extract the spring bar. Repeat for the other end. Insert the new strap in the same position, ensuring the spring bar is fully seated. Do not force: the movement should be fluid and smooth.

Yes, the Club 713 is fully compatible with aftermarket straps measuring 18mm in lug width. In fact, 18mm is an open standard that permits considerable choice between leather, fabric, and rubber. We recommend verifying that the strap passant adapts to the case shoulders, which on the Club are relatively delicate. The best results are achieved with artisanal straps that respect the watch's original proportions.

The lifespan of a leather strap depends on the tanning quality and daily usage. Superior-quality leather (shell cordovan or vegetable-tanned hide) can last 3–5 years of regular wear before replacement is needed. Standard calf leather has a slightly shorter lifespan, around 2–3 years. Factors such as humidity, sun exposure, and periodic maintenance significantly influence durability. NATO fabric straps tend to last longer, while rubber maintains its characteristics for 4–6 years.
