Rado DiaStar Original R12403633 — Timeless Two-Tone Elegance for Her

The Rado DiaStar Original in reference R12403633 brings quiet luxury to the wrist with a sculpted 27.3mm oval case and a warm gold dial. Diamond hour markers catch the light against the dial, while the two-tone bracelet balances silver and gold for a refined, everyday-to-evening look. It is a Swiss-made women's timepiece designed to feel as considered as it looks.

A scratch-resistant sapphire crystal protects the gold dial, which displays hours, minutes and a date function through polished, diamond-set markers. The polished bezel frames the oval silhouette, and the two-tone stainless steel bracelet secures with a folding deployment clasp. Water resistance of 30 meters (100 feet) guards against everyday splashes and rain.
