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

The Nivada Grenchen Antarctic 35005M01 features a lug width of exactly 18 millimetres. This measurement represents the distance between the inner edges of both lugs and is essential for selecting a compatible strap. The construction tolerance is minimal, so ensure you measure precisely before purchasing an aftermarket strap.

The choice depends on your lifestyle and aesthetic preferences. For classic valorisation, we recommend an alligator strap with vegetable tanning in brown or black tones, which dialogues perfectly with the natural patina of the steel case. For a sport-oriented approach, a NATO cotton strap maintains coherence with the watch's functional heritage. For humid environments or dynamic activities, FKM rubber with textured finish offers durability and practicality without sacrificing aesthetics.

The Nivada Grenchen Antarctic 35005M01 uses a straight lug system without lugs removable from the sides (spring bars). Remove the current strap using a dedicated tool (spring bar tool) or thin stylus: exert light downward pressure on one of the two small side holes to release the bar. Insert the new strap ensuring the bar falls correctly into the lug seat. Verify that the strap is centred and firmly secured before wearing the watch.

Yes, provided the aftermarket strap has a lug width of exactly 18mm and is fitted with standard 18mm spring bars. We recommend verifying that the strap thickness does not exceed 3-4 millimetres in the lug seating zone to avoid excessive play. Artisanal bespoke straps guarantee maximum compatibility and structural longevity.

The longevity of a natural leather strap depends on the material, frequency of use and environmental conditions. An alligator strap with vegetable tanning typically lasts 5-7 years with daily wear, thanks to the naturally resistant fibrous structure. A calf strap, more delicate, requires regular maintenance (cleaning, conditioning with specific creams) and has an average life of 4-5 years. Natural rubber resists 8-10 years under normal conditions. The patina that develops on natural materials is a positive aspect of ageing, not a defect.
