Nivada Grenchen
Super Antarctic 32025A01— lug 20mm

The Nivada Grenchen Super Antarctic 32025A01 features a lug width of 20 millimetres. This specific, unconventional measurement is characteristic of the model and requires straps manufactured with precision engineering to guarantee perfect compatibility. Always verify the exact measurement before ordering an aftermarket strap.

For the 32025A01, materials that align with its design philosophy are recommended: high-quality alligator for purist elegance, vegetable-tanned calf for warm tactile quality, heavyweight canvas NATO for authentic sporting character, and butyl rubber for waterproof practicality. Selection depends on intended use and wearing context. All straps must feature certified 20mm lug width.

Strap replacement requires a spring bar removal tool. Position the tool in the lateral groove of the case lug, gently push the spring bar inward and retract the strap. Reverse the procedure to install the new 20mm strap. If uncertain, entrust the operation to a professional to prevent case damage.

Yes, aftermarket 20mm straps can be used provided they are manufactured with precision and respect the exact certified lug width. Artisanal straps from specialised manufacturers guarantee secure compatibility and superior construction quality compared to standard industrial production. Always verify technical specifications before ordering.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with ordinary use, varying according to humidity exposure, physical activity, and wearing frequency. The natural patina that develops over time indicates authentic ageing, not deterioration. Periodic maintenance with specialist leather conditioners extends longevity and preserves aesthetic integrity.
