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

The Nivada Grenchen Antarctic 35005M16 features an 18mm lug width. This means the pins (spring bars) that secure the strap are spaced 18 millimetres apart. This is a precise specification and is not interchangeable with standard 16mm or 20mm straps. Always measure your watch's lug width before ordering to avoid compatibility issues.

The best choice depends on your intended use and aesthetic preferences. For elegant occasions, we recommend an alligator strap with a tight grain (black or chocolate brown) or vegetable-tanned leather (cognac or aged burgundy tones). These materials respect the minimalist integrity of the 35mm case. For versatile, casual wear, a heavyweight cotton NATO in khaki or grey offers practicality without compromising the vintage character. For sports use, a technical rubber strap with subtle texture ensures grip and water resistance.

Changing the strap requires a spring bar tool. Position the watch with the lug oriented horizontally upwards. Insert the tool into the gap between the lug and case, then gently lift to release the tension spring. Repeat at the other end. Once both springs are freed, the strap comes away. For your new strap, align the lugs to the spring bars and push the bars into their seatings until they click into place. Do not force: if a bar doesn't seat properly, adjust your angle. We recommend performing this task on a soft cloth surface to avoid scratches.

Yes, absolutely. The 35005M16 uses standard 18mm spring bars, so any quality aftermarket strap with 18mm lugs is compatible. Milanostraps.it offers a dedicated 18mm collection: vegetable-tanned leather, alligator, NATO, and technical rubber. Choose a strap with appropriate thickness (approximately 4–5mm for leather) to ensure a harmonious transition between case and strap.

Durability depends on frequency of wear, climate conditions, and material quality. A handcrafted vegetable-tanned leather strap worn daily typically has a serviceable life of 3–5 years before replacement. Prolonged exposure to moisture, direct sunlight, or temperature extremes accelerates ageing. Alligator leather straps tend to last longer (5–7 years) due to the natural resilience of the scale structure. To preserve your strap, avoid prolonged water contact, dry gently after any splashes, and store in a dry environment. Periodic maintenance—such as applying natural oil every six months—extends the strap's lifespan.
