Frequently asked questions

What is the lug width of the Nivada Grenchen Super Antarctic 32025A04?

The lug width of the Super Antarctic 32025A04 is 20 millimetres. This measurement is critical for selecting compatible straps: it is measured from one lug shoulder to the other at the strap attachment point. Accurate measurement is essential to ensure correct visual proportions and perfect fit to the watch's lugs.

Which type of strap is most suitable for the Nivada Grenchen Super Antarctic 32025A04?

For the Super Antarctic 32025A04, an alligator strap with vegetable tanning is recommended for formal use, robust calf leather for daily wear, or FKM rubber for technical and wet environments. Your choice depends on intended use: a cognac alligator creates elegant contrast with the satin steel case, whilst black calf emphasises the watch's instrumental character. Rubber guarantees durability under extreme conditions.

How do I change the strap on the Nivada Grenchen Super Antarctic 32025A04?

Changing the strap on the Super Antarctic 32025A04 requires only a few steps: remove the current strap by unscrewing the spring bars from the lugs with an appropriate tool (strap remover or screwdriver). Insert the new strap, aligning the holes to the lugs, and reinsert the spring bars. Verify that the strap is fully secured before wearing the watch. If you lack confidence, consult a professional: MilanoStraps offers strap-change service by appointment at the Casati Milano atelier.

Can I use an aftermarket strap on a 20mm lug width?

Yes, any strap with 20mm lug width is compatible with the Super Antarctic 32025A04. MilanoStraps' bespoke straps are constructed specifically for this width, guaranteeing superior build quality and materials compared to factory alternatives. Always verify that the seller explicitly confirms 20mm compatibility before purchasing.

How long does a leather strap last on a dive watch like the Super Antarctic?

A quality leather strap on a watch such as the Super Antarctic 32025A04 typically lasts 3–5 years with daily use, provided it is not frequently exposed to water. The watch's 300-metre water resistance does not require prolonged exposure: it is advisable to remove leather straps before diving or extended wet exposure. Alternating with FKM rubber in summer significantly extends leather strap longevity.
