Strap for Super Antarctic 35 Black - White Luminova / Stainless Steel / Black

The lug width of the Nivada Grenchen Super Antarctic 35014M17 is 18 millimetres. This dimension is specific to 1950s watchmaking standards and is crucial when selecting a compatible strap. To verify the measurement, measure the distance between the inner shoulders of the lugs using a calliper, positioning it perpendicular to the buckle.

The ideal strap for the 35014M17 is vegetable-tanned leather, such as Tuscan Sella: it enhances the watch's explorer heritage and develops a captivating patina over time. Alternatively, alligator offers discrete elegance, whilst a robust canvas NATO strap provides practical versatility and enables notable aesthetic transformations.

To change the strap, extract the pin from the lug using a dedicated tool (spring bar tool). Position the small screwdriver or hook under the pin, gently push towards the opposite side of the lug until the inner spring is released, then extract the pin. Repeat the procedure on the other side. Insert the new strap by aligning the holes with the pins and reposition the pins ensuring they click firmly on both sides.

Absolutely. Any strap with a compatible 18-millimetre lug width can be mounted on the 35014M17. Artisanal aftermarket straps often offer superior construction quality and carefully selected materials, allowing you to personalise the watch according to your style and usage requirements.

The durability of a leather strap depends on the material and usage. A high-quality vegetable-tanned strap can last 3-5 years with ordinary maintenance (periodic cleaning, drying after humidity exposure). Alligator and shell cordovan have similar lifespans. A canvas NATO strap resists up to 7-10 years. Leather ageing does not imply functional deterioration, but rather aesthetic evolution of the patina.
