Since antiquity, man has searched for the best ways to measure time. The Egyptians, thousands of years before Christ, had already developed a very precise calendar. Later, the Greeks invented the clepsidre, an instrument consisting of a perforated vase that had marks by which you could measure the time taken for the water to escape. Then in the 3rd. Century AD, the sand clock was invented, an instrument that would last until the end of the 16th century.
Leonardo da Vinci, painter, sculptor, inventor and scientist, developed a number of scientific theories at the beginning of the 16th century. At the time, many of these, including great advances in the study of time-keeping, were ignored. It is only centuries later, with the benefit of modern scientific knowledge, that we can appreciate his brilliance.
To pay homage to this genius of invention and engineering, WM of Switzerland has proudly entitled its latest creation, equipped as it is with the advanced Power Reserve, with his name: Leonardo Réserve de Marche.
