Nivada Grenchen
Super Antarctic 32031A16— lug 20mm

The lug width of the Nivada Grenchen Super Antarctic 32031A16 is 20mm. This measurement is specific to the model and derives from the proportional design of the 38mm case. It is essential to measure correctly before purchasing a new strap by placing the ruler between the internal attachment points of the lugs.

For the Super Antarctic 32031A16, we recommend alligator or vegetable-tanned calf leather straps. Alligator provides formal elegance with natural grain texture, whilst vegetable-tanned calf develops a patina over time that perfectly dialogues with the ageing of the stainless steel case. For maritime use, robust nylon NATO straps are equally appropriate.

Changing the strap requires removing the spring bars (elastic pins) that secure the strap to the lugs. Use a professional remover or a thin lever to compress the internal catches and release the pins. On the Super Antarctic 32031A16, given the integrated case design, service by a specialised atelier is recommended to ensure precision and prevent damage.

Yes, any 20mm strap is technically compatible with the Super Antarctic 32031A16. However, the choice of material (alligator, calf, rubber) and finish (gold, satin steel) should reflect the tool character and Swiss refinement of the model. Avoid straps with excessive decorative design.

A natural leather strap (calf or alligator) typically lasts 3-7 years with daily use, depending on care and moisture exposure. Vegetable tanning ages more gracefully than industrial tanning. If you wish to preserve the original strap, it is advisable to alternate it with a NATO or rubber strap for summer occasions or water activities.
