Strap for Super Antarctic 3.6.9. Black - No Vintage Effect / Stainless Steel / Beads of Rice

The lug width of the Nivada Grenchen Super Antarctic 32039A04 is 20mm. This measurement represents the distance between the inner edges of the case lugs, and is essential for selecting a compatible strap. Measuring incorrectly could lead to purchasing an unsuitable strap, so we recommend verifying this dimension with a ruler before ordering.

The best strap for the Super Antarctic 32039A04 depends on your intended use and personal preferences. For formal elegance, we recommend vegetable-tanned alligator in dark brown or cognac; for tactical versatility, an ardoise grey or dark blue NATO; for refined aesthetics and patina development, a shell cordovan. Calf leather offers a balanced compromise between versatility and perceived quality. All these materials in 20mm size are carefully curated in our catalogue.

The strap is changed by extracting the spring bars—the metal rods that hold the strap in place. Using a spring bar tool, gently press the bar inward toward the case to create space, then slide out the old strap end. Insert the bar into the new strap (ensuring the 20mm size is correct), and repeat on the other side. If you lack experience, seek assistance from a professional strap-changing service.

Yes, aftermarket straps are fully compatible with the Super Antarctic 32039A04, provided they meet the 20mm lug width requirement. In fact, artisan straps allow you to entirely personalise the character of your watch, choosing from materials, finishes, and colours that standard market options do not offer. Simply ensure that the strap is made by experienced craftspeople, as the quality of the leather and precision of craftsmanship make a genuine difference.

The lifespan of a leather strap depends on leather quality, tanning method, usage, and maintenance. A strap in alligator or vegetable-tanned shell cordovan can last 5–8 years of daily use, developing precious patina. Quality calf leather has similar longevity. NATO, made of synthetics, can last even longer if kept clean. To extend lifespan, avoid prolonged exposure to excessive moisture and occasionally apply a protective balm specifically formulated for leather.
