Strap for Antarctic 35 White - White Luminova / Stainless Steel / Black

The lug width of the Nivada Grenchen Antarctic 35005M17 is exactly 18mm. This measurement is specific to the model and reflects the original proportions of the 1970s design. To verify with certainty, measure the distance between the two attachment holes for the strap on the case.

It depends on your intended use. For formal or business-casual contexts, we recommend vegetable-tanned alligator leather or French calf with medium grain. For sporty or summer contexts, cotton NATO straps preserve the authentic tool-watch character of the piece. For aquatic activities, vulcanised butyl rubber (FKM) ensures complete resilience.

Strap replacement requires a precision spring bar tool. Position your watch on a soft, stable surface and gently insert the tool under the upper lug to release the spring. Remove the old strap, then insert the spring end into the new strap, align the lugs, and press until you hear the click. Verify that the strap is fixed symmetrically on both sides.

Yes, absolutely. Any strap with an 18mm lug width is compatible with the Nivada Grenchen Antarctic 35005M17. Milanostraps.it offers a complete collection of artisanal 18mm straps, from natural leather to technical fabrics, all tested for compatibility with this size range.

The lifespan of a leather strap depends on the tanning method and frequency of wear. A vegetable-tanned alligator strap typically lasts 3-5 years with moderate daily wear. French calf resists 2-4 years. To extend the life of your strap, avoid prolonged exposure to moisture and occasionally apply a conditioner specifically formulated for watch leather.
