This jewellery watch, Delaneau’s latest creation, is a veritable collector’s item. It features an ingenious protective golden shutter which slides smoothly open and shut on 54 ruby bearings around the watch case. An interior spring-break ensures optimal positioning. Available in polished or gem-set yellow or white gold, the shutter button can be set with a cabochon ruby, sapphire or emerald, or three small diamonds. Versions with mechanical or quartz movements are available with a supple gold bracelet or coloured crocodile strap. The gold, lapis-lazuli, white mother-of-pearl, onyx or silicium dials are protected by a sapphire crystal. Water-resistant to 30 m.
