Strap for Klassik 36 Gold PVD / Silver / Beige Suede

The lug width is 18 millimetres. This is a refined standard for compact cases, requiring custom-built watch straps incompatible with standard 20 or 22mm lug widths. To verify the measurement, measure the internal spacing between the two lugs where the strap fastens.

Depends on use: vegetable-tanned calf for authentic chromatic evolution; alligator for formal elegance; NATO canvas for sporting versatility; FKM rubber for humid environments. The Archimede Klassik is a minimalist German watch: every material must reflect this aesthetic philosophy without excess.

The lug is fixed: the strap attaches via two passants recessed into the case. Use a spring bar tool to release the metallic springs holding the strap in the passants. Insert the new strap, aligning the holes with the springs, then push until the locking click engages. The operation requires care to avoid scratching the case.

Absolutely yes, provided it respects the exact 18mm lug width. Quality aftermarket straps (leather, rubber, NATO) are fully compatible and often superior to original factory options. Build quality and material selection depend on the manufacturer, not the original brand.

A full-grain leather strap with vegetable tanning typically lasts 3-5 years with daily wear, considering exposure to perspiration, humidity, and continuous movement. Natural patina evolves progressively, increasing character. With periodic rotation between straps and moderate cleaning, longevity extends to 7-8 years. Vulcanised rubber lasts longer (5-7 years) but ages visually more markedly.
