FAQ

What is the lug width of the Armin Strom Gravity RG14-DF.90?

The Armin Strom Gravity RG14-DF.90 features a 20 mm lug width. This dimension is standard for sports and dress watches exceeding 42 mm in diameter, ensuring visual balance proportional to the rose gold case mass.

Which strap should I choose for the Gravity RG14-DF.90?

We recommend alligator or calf leather straps that respect the aesthetic integrity of the skeletonised movement. Alternatively, a neutral-toned NATO (black, brown) offers sporting versatility. High-density rubber is ideal for daily wear and moisture resistance.

How do I change the strap on this watch?

Strap replacement requires removal of the lug bars using a dedicated tool. Position the watch on a soft cushion, locate the small holes on the lugs, and gently slide the bar laterally. Insert the new strap, ensuring the keeper is properly aligned. If inexperienced, consult a professional.

Are there aftermarket straps compatible with the RG14-DF.90?

Yes, all straps with a 20 mm lug width are compatible. Milano Straps offers an extensive selection of leather, NATO, rubber, and shell cordovan in 20 mm, fully customisable and ready to ship. Always verify that the keeper width matches the case.

What is the lifespan of a leather strap for this model?

A quality leather strap subjected to moderate wear (3–4 days weekly) has an estimated lifespan of 3 to 5 years. Vegetable-tanned leather ages beautifully, developing an appealing patina. Rubber and NATO offer greater longevity under mechanical stress and humidity conditions.
