A collection inspired by the first waterproof watch in history

It all started with an idea: a modern reinterpretation of the very first waterproof watch in history.

Its curved design is for us a symbol of elegance, modernity and refinement. Complex curves and refined details give it an irresistible charm.


A slim profile of 10.9mm

The Ellipse B2201 features a polished 40mm cushion case in stainless steel, designed with rounded curves to fit any wrist (even the slimmest). Featuring a double-domed sapphire crystal, the watch offers an elegant 10.9mm thickness (9.06mm without glass).


Powered by one of the biggest movement manufacturers in the industry, the robust Swiss Made La Joux-Perret G100 automatic calibre is entirely manufactured, assembled and controlled at the La Joux-Perret Manufacture in La Chaux-de-Fonds, Switzerland. This manufacture movement is known for its accuracy, reliability and longevity, with an extended power reserve of 68 hours (weekend proof).


High-end finish with diamond-cut bevelling and rhodium-plated screws, meticulously polished and heat blued to the highest standards of watchmaking craftsmanship. Solid tungsten rotor decorated with "Côtes de Genève" and engraved in Switzerland with the name and logo of the Maison Boanton in black and tangerine.
