Strap for Super Antarctic 3.6.9. Tropical / Stainless Steel / Tropic

The lug width of the Nivada Grenchen Super Antarctic 32031A01 is 20mm. This dimension is measured as the internal distance between the two spring bars located at 12 and 6 o'clock on the case. It is a specific measurement that ensures compatibility exclusively with 20mm straps: correct pairing eliminates lateral play and guarantees perfect geometric alignment between the lugs and the strap's passant.

For the 32031A01, alligator or shell cordovan straps are indicated for those seeking formal elegance and chromatic evolution over time. The vegetable-tanned leather strap represents the ideal compromise between tactile quality and sustainability. For more rigorous applications, a NATO strap in cotton or vulcanised rubber emphasises the model's instrumental heritage. The choice depends on usage: evening elegance requires alligator; daily wear favours vegetable leather or NATO.

Strap replacement requires a spring bar removal tool (a small specific instrument). Position the watch on a stable support with the 12 o'clock lug facing up, identify the small circular hole in the pin, insert the flat tip of the tool into the hole and gently push downwards to release the internal spring pressure. The pin will come out: repeat the procedure at 6 o'clock. Insert the new strap by aligning the passants with the holes, reinsert the pins and verify the locking click.

Yes, any quality strap with 20mm passants is fully compatible with the 32031A01. Compatibility is guaranteed by matching lug width. Verify that the strap has appropriate thickness (not less than 1.4mm) and that the passants fit into the case holes without forcing. An artisanal aftermarket strap often improves overall quality compared to the factory strap.

A quality leather strap (alligator, cordovan, or vegetable-tanned leather) has an average lifespan of 3-5 years of moderate daily use. Longevity depends on moisture exposure, frequency of wear and tanning quality. Vegetable-tanned leather tends to last longer due to fibre density. NATO or rubber straps have indefinite lifespan, requiring only periodic cleaning. Proper maintenance (rapid drying after wetting, avoidance of prolonged direct sunlight) significantly extends strap life.
