Strap for Super Antarctic 3.6.9. Black - No Vintage Effect / Stainless Steel / Brown

The lug width of the Nivada Grenchen Super Antarctic 32039A16 is 20mm. This measurement must be respected precisely when selecting an aftermarket strap. To verify it, use a digital caliper positioned between the two lugs at the contact point of the strap: the distance will be exactly 20mm.

For the Super Antarctic 32039A16, we recommend vegetable-tanned alligator in dark brown tones or a cotton-polyester NATO. Alligator delivers understated elegance without competing with the case's technical details; NATO offers sporty versatility. Vulcanised rubber is ideal if durability and comfort are priorities. Avoid shell cordovan: its lustre conflicts with the watch's technical sobriety.

Use a standard spring bar tool: insert the tip under the metal tube connecting the strap to the case, apply gentle downward pressure until the spring releases, and remove the strap. Position the new strap and reinsert the spring bar, ensuring the spring catches securely on both sides. Verify the strap is aligned symmetrically with the lugs.

Yes, a 20mm aftermarket strap is fully compatible with the Super Antarctic 32039A16, provided it meets ISO 4749 standards and thickness does not exceed 3.5mm. Verify also the overall length: the strap must cover the wrist without obvious excess. Bespoke straps from Atelier Casati Milano are dimensioned specifically for this reference.

A high-quality vegetable-tanned alligator strap lasts approximately 5–7 years with daily use, extendable to 10+ years with regular maintenance (annual conditioning with natural waxes). Longevity depends on ambient humidity, frequency of use, and tanning quality. Bespoke straps crafted from premium leathers and reinforced stitching consistently exceed this range. Vulcanised rubber resists 8–12 years without particular maintenance.
