Dressed in a solid stainless steel case, this timepiece’s aesthetic excellence is further highlighted by its sapphire crystal type box, its slightly domed dial surmounted by appliqués and its perfectly dimensioned hands.

The collection is named Duobox in reference to its two box sapphire crystals, formerly made of plastic. The first protects the dial and allows an optimal reading thanks to its anti reflective treatment; the second allows you to admire the automatic movement in detail and at all times. The contact of the sapphire with the skin offers to the wearer an optimal comfort.
