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

The lug width of the Nivada Grenchen Antarctic 35004M04 is 18.00mm. This measurement represents the distance between the two metal lugs around which the strap is secured. It is essential to verify this measurement precisely before purchasing a strap, using a digital calliper or by measuring the lugs with a flexible tape measure.

For the 35004M04, we recommend straps in vegetable-tanned leather (cognac, natural tobacco, or dark bordeaux tones), which respect the vintage aesthetic and historical authenticity of the model. Alternatively, NATO straps in expandable cotton faithfully replicate the spirit of the original polar expeditions. For contemporary use, a vulcanised FKM rubber solution offers comfort and durability without compromising the character of the watch. All straps must have an 18mm lug width.

To change the strap: (1) obtain two flat-tipped tools (springbar tool or two fine screwdrivers); (2) place the watch on a soft surface; (3) insert the tool into the small hole next to one of the lugs and push towards the centre to compress the spring; (4) extract the lug from the case; (5) repeat for the other side; (6) position the new strap (18mm lug width) by threading one lug at a time and ensuring the spring is fully seated.

Absolutely yes. The Nivada Grenchen Antarctic 35004M04, with its 18mm lug width, is perfectly compatible with any artisan strap of certified quality with the same lug width. Aftermarket straps in vegetable-tanned leather, alligator or rubber are often preferable to vintage original straps, as they offer greater durability, comfort and aesthetic customisation possibilities. Compatibility is guaranteed by respecting the 18mm measurement.

The durability of a leather strap depends on the tanning quality, usage and maintenance. A strap in high-quality vegetable-tanned leather (such as those recommended for the Antarctic 35004M04) typically lasts 3 to 5 years of regular use, developing a fascinating patina over time. Intensive use, frequent exposure to moisture or sweat accelerates wear. To extend the life of the strap, we recommend drying it after water contact, avoiding harsh softeners, and allowing the strap to rest on alternate days to daily use.
