Nivada Grenchen
Super Antarctic 32032A20— lug 20mm

The lug width of the Nivada Grenchen Super Antarctic 32032A20 is 20mm. This is a classical standard for 38mm diameter watches and ensures balanced proportions. Always measure with a digital calliper between the two lugs supporting the strap to verify accuracy before purchase.

The ideal strap depends on your use case: for formal elegance we recommend dark brown alligator; for historical authenticity, a grey-blue NATO; for aesthetic evolution over time, Italian leather in vegetable tanning; for marine or humid environments, vulcanised FKM rubber. Each material highlights different aspects of the watch.

To change the strap, proceed as follows: 1) Remove the spring bars from the lugs using a specialised tool or small screwdriver; 2) Extract the old strap from the lug holes; 3) Insert the new strap (20mm width) into the lug housings; 4) Reinsert the spring bars until they click into place. Work on a clean surface to avoid losing small components.

Yes, any strap with a 20mm lug width is compatible with the Super Antarctic 32032A20. Ensure the strap has been correctly measured (between the two lugs) and the width is exactly 20mm. Undersized or oversized straps will not fit correctly and may damage the spring bars.

Durability depends on the material and usage: a natural calf strap lasts 3-5 years with daily wear; alligator reaches 5-7 years thanks to greater density; shell cordovan easily exceeds 7-10 years. Vegetable tanning offers better ageing than synthetic methods. Regular maintenance with specific creams significantly extends durability.
