Drawing its inspiration from a point of evolution midway between the pocket watch and the wristwatches of the 1940s, the WW1 (Wrist Watch 1) brings together the stylistic vogues of the Roaring Twenties with curves borrowed from fob models, wire handles soldered to
the case and a thin, elegant and robust leather strap. Enhanced by a new, more striking and resistant silver alloy, the Vintage WW1 Argentium® evokes the spirit and incomparable allure of the very first wristwatches.
