Strap for Antarctic 35 Eggshell - Beige Luminova / Stainless Steel / Beads of Rice

The lug width of the Nivada Grenchen Antarctic 35001M04 is 18 millimetres. This measurement refers to the internal distance between the two lugs where the strap connects to the case. It is essential to respect this specification to ensure correct mounting and strap stability on the wrist.

The best strap depends on your intended use. For historical authenticity, we recommend vegetable-tanned alligator leather with natural patina. For everyday versatility, a structured calf leather with pronounced grain works excellently. For water exposure or sports activities, a cotton NATO strap or vulcanised rubber strap offers maximum practicality and durability.

Strap replacement is performed using the spring bars that secure the strap to the case lugs. Using a dedicated spring bar tool, remove the bar from the first lug, extract the old strap, and insert the new one, then secure the bar in the opposite lug. The operation requires care to avoid damaging the case.

All straps with an 18-millimetre lug width are compatible with the 35001M04. We specifically recommend leather straps in alligator, calf, or shell cordovan with vegetable tanning, and alternative options in NATO or technical rubber. MilanoStraps straps are all verified for compatibility and available in multiple finishes.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years of daily wear, provided regular maintenance and protection from excessive moisture. Durability depends on climate, frequency of use, and care applied. NATO or rubber straps offer superior longevity, lasting up to 7–10 years.
