Strap for Club Automat Datum

The Club 771 features a lug width of exactly 20 millimetres. This measurement is the critical specification when selecting a replacement strap: measure the distance between the two lugs of the case to confirm compatibility. A 20mm strap will fit perfectly without lateral play.

It depends on intended use and aesthetic preference. For classical elegance, a shell cordovan or vegetable-tanned calf leather strap enhances the case's Germanic minimalism. NATO straps in grey, navy, or black offer sporting versatility while maintaining the sober character. For formal settings, grey tortoiseshell alligator creates a refined optical transition. The ideal strap must possess a precisely 20mm lug width.

The lug spring bars protrude slightly from the case. Using a dedicated spring bar tool or a small flat screwdriver tip, gently depress one spring bar to release it from its seat, then withdraw the old strap. Insert the new strap (20mm) allowing the spring bar to snap back into position. Repeat on the opposite side. Never force: spring bars must click naturally. If resistance occurs, verify that your strap actually measures 20mm in width.

Absolutely. High-quality aftermarket straps produced by recognised tanneries (cordovan, vegetable-tanned calf, woven NATO) guarantee compatibility and durability superior to generic straps. The sole requirement is that the lug width be precisely 20mm. An aftermarket strap in premium leather, with appropriate finish and steel deployant clasp, improves both the ergonomics and aesthetics of your Club 771 compared to stock straps.

A vegetable-tanned calf strap typically lasts 3–5 years with daily wear and basic maintenance (dry air, avoiding prolonged showers). Shell cordovan, owing to its density, may reach 7–10 years. Longevity depends on: frequency of use, climate conditions, water exposure, and maintenance practices. A well-cared strap develops natural patina that enhances aesthetic appeal. When leather loses elasticity at the lug or displays tears, it is time to replace the strap while preserving the intact case.
