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

The Nivada Grenchen Antarctic 35005M14 features an 18mm lug width. This is the historical standard for wristwatches up to 36mm in diameter and ensures perfect aesthetic balance between case and strap. To verify the lug width accurately, we recommend a consultation at Atelier Casati Milano, where we extract the spring bars by appointment.

For this historical model, we recommend a European alligator or shell cordovan strap that age naturally and echo the instrumental aesthetic of the watch. If you prefer versatility, an 18mm NATO strap in heavy canvas offers quick changes without tools. For humid environments, FKM rubber is reliable and understated.

Strap replacement requires extraction of the spring bars from the case using specific tools (spring bar pliers or similar). If you lack experience, Atelier Casati Milano offers the service by appointment in Milan. The process is straightforward and protects the case from accidental scratches during operation.

Any strap with an 18mm lug width is compatible. Milanostraps.it offers a complete collection of artisanal straps for 18mm lug width: leather (alligator, cordovan, calf), NATO, and rubber. All are customisable online and delivered promptly.

A quality leather strap, worn daily, typically lasts 3-5 years. Durability depends on exposure to moisture, perspiration, and maintenance. An alligator or well-cared-for shell cordovan can exceed 7-8 years. Vegetable-tanned leather ages aesthetically, developing characteristic patina, but requires protection from prolonged bathing.
