Strap for Club Campus 38 J9

The Nomos Club 737.S2 features a 20 mm lug width. This measurement is essential for selecting compatible straps. To verify it, measure the space between the two attachment points on the caseback: it must correspond exactly to 20 mm. Even a minor variation can compromise the fit.

For the Club 737.S2, we recommend a vegetable-tanned alligator strap (chocolate brown or black) or shell cordovan. Both amplify the sober and minimalist character of the watch. For summer, a grey talpa canvas NATO offers practicality without sacrificing elegance. Rubber is discouraged if the watch is intended for formal contexts.

Changing the strap on a Nomos Club 737.S2 requires specific tools: a spring bar tool and a stable surface. Insert the tool into the lateral slot of the lower lug to release the internal spring, then extract the old strap. Position the new strap by aligning it perfectly and press until you hear the safety click. If you are not skilled, consult a professional watchmaker.

All straps with a 20 mm lug width are compatible with the Club 737.S2, regardless of material: leather (alligator, calf, shell cordovan, suede), fabric (NATO, canvas, nylon), elastomers (rubber, FKM). Ensure that the width is exactly 20 mm and that the attachments are designed for the case thickness.

A quality leather strap on a Nomos Club 737.S2, with daily wear (5-6 days per week), lasts on average 18-24 months. Shell cordovan is more durable and can reach 30-36 months. Vegetable-tanned alligator tends to age more rapidly (12-18 months), developing characteristic creasing. Durability also depends on humidity, sun exposure, and cleaning frequency.
