Strap for Super Antarctic 3.6.9. Brown - White Luminous / Stainless Steel / Black - White

The lug width (lug opening) of the Nivada Grenchen Super Antarctic 32040A15 is 20 millimetres. This measurement represents the distance between the inner edges of the case lugs and is essential for selecting a compatible strap. To verify it accurately, measure directly the space between the two lugs: if you obtain exactly 20mm, your strap will anchor correctly.

The choice depends on your use case and wrist proportions. For sartorial elegance, we recommend an alligator strap with fine grain or calf leather with vegetable tanning, which develops natural patina over time. To maintain the functional spirit of the watch, a nylon NATO or rubber strap with coarse texture are excellent options. A deployante clasp ensures secure anchoring and uniform pressure distribution.

Position the watch on a stable surface and locate the lugs at each end of the case. Using a spring bar tool, apply gentle inward pressure toward the centre of the case to compress the internal spring of the lug. Remove the spring bar from the old strap's holes, then insert the new spring bar into the holes of the new strap and anchor it to the case lugs. Proceed with precision to avoid scratches.

Yes, provided it is sized for a 20mm lug width. The Nivada Grenchen Super Antarctic 32040A15 accepts any quality strap with this measurement: leather, NATO, rubber, elastomers. We recommend choosing straps crafted by artisans, which offer superior construction and finishing compared to industrial products. A deployante clasp is strongly recommended for wearing security.

The lifespan of a leather strap depends on usage, climate, and tanning quality. With vegetable tanning and ordinary care, a well-made strap can last 2–4 years of daily wear, developing patina and character. Excessive humidity and sweat accelerate wear; in humid environments, consider frequent rotation with other straps. When the strap shows signs of structural failure, it is time to replace it to avoid losing your watch.
