Universal Genéve 10359 Cioccolatone 18k Rose 1959

This Universal Genève square “Cioccolatone” in 18k rose gold is a rare and striking design produced only between 1955 and 1962. With its sculptural case, stepped bezel and impressive wrist presence, it stands apart from traditional UG dress watches. The warm rose dial, elegant hands, and refined proportions highlight the charm of mid-century Swiss design.

This reference 10359-1 was made in only a few hundred pieces, making it especially desirable among collectors. Our example comes in excellent overall condition with a clean dial, strong case, and freshly serviced automatic movement — a true UG gem.
