Frequently asked questions

What is the lug width of the Rado Oval R15946103?

The Rado Oval R15946103 features a 20mm lug width. This dimension is standard for this model and represents the internal distance between the two case lugs where the strap is attached.

Which strap is recommended for the Rado Oval R15946103?

For the Rado Oval, we recommend polished alligator straps for a formal aesthetic, vegetable-tanned calf leather for daily elegance with natural patina development, or canvas NATO straps for contemporary versatility. Your choice should reflect the intended usage: alligator highlights the modernity of the Cermet case, whilst vegetable-tanned leather develops a compelling patina over time.

How do I change the strap on the Rado Oval R15946103?

Strap replacement requires a spring bar removal tool. Position the watch on a soft surface, locate the small holes in the lugs, insert the spring bar tool, and gently push outward to release the original spring bar. Repeat on the opposite lug, then install the new strap by reversing the procedure.

Is an aftermarket strap compatible with the Rado Oval R15946103?

Yes, any strap with a 20mm lug width is fully compatible. At Milano Straps we curate artisanal straps in leather, NATO, and rubber, specifically selected for watches of this calibre. Simply verify that the width measurement matches 20mm precisely.

What is the lifespan of a leather strap on the Rado Oval?

A quality vegetable-tanned leather strap typically lasts 3-5 years with daily wear, provided regular maintenance is observed. Longevity depends on usage intensity, humidity exposure, and treatment protocol. Alligator or shell cordovan straps, owing to superior leather density, can achieve 7-10 years of reliable service.
