Strap for Super Antarctic 3.6.9. Tropical / Stainless Steel / Brown Racing

The lug width of the Nivada Grenchen Super Antarctic 32031A23 is 20mm. This specification allows the use of any compatible 20mm strap. To verify the measurement, simply unscrew one of the lateral spring bars and measure the distance between the two central pins.

The choice depends on intended usage. For formal occasions, we recommend an alligator strap in brown or black, which enhances the elegance of the brushed steel case. For daily wear, a hand-dyed vegetable-tanned calf leather strap in cognac represents the ideal compromise between aesthetics and practicality. For outdoor activities, a NATO or FKM rubber strap guarantees durability and easy maintenance.

The replacement is straightforward and requires a small Phillips head screwdriver. Locate one of the spring bars on the case, insert the screwdriver tip into the slot, and gently rotate to open the internal lock. Once opened, the lug will slide out. Reverse the process with the new strap, ensuring both locking rings click firmly into position.

Yes, any quality 20mm strap designed for watches is compatible with the Super Antarctic 32031A23. Verify that the strap is in good condition, that the terminals are rectangular and free of sharp edges that might scratch the original lugs, and that the total length permits comfortable deployment of the clasp around the wrist.

A high-quality natural leather strap, particularly one produced with vegetable tanning, typically lasts 3–5 years with daily use and basic care. Longevity depends on frequency of wear, exposure to water and perspiration, and regularity of cleaning. Monthly cleaning with a damp cloth and application of a light leather conditioner twice yearly significantly extends the strap's lifespan.
