The Arnold & Son Ultra Thin Tourbillon Onyx

When darkest black becomes colour – Our Ultrathin Tourbillon Onyx Edition reveals the full depth of onyx, a stone chosen for its intense, almost hypnotic presence. Paired with one of the slimmest flying tourbillons on the market, it creates a striking contrast between absolute minimalism and mechanical complexity. Limited to just eight pieces in 5N red gold and eight in platinum, this creation embodies our pursuit of purity, precision and timeless elegance.
