In 2010, Hermès introduced the “Carré H”, a square timepiece created by Marc Berthier, with a modern aesthetic, designed for instant legibility. It returns in a new style: Marc Berthier has enlarged the square by a few millimetres and opted for light effects, playing across the steel case with its polished and microbead-blasted finishes, on the dial with its right-angled guilloché work, and on the facetted hands and numerals. This perfectly balanced use of light harmoniously accentuates the clarity of the design, the softened edges of the square, the curved profile of the case, and the cylindrical crystal. Finally, the exclusive font of the numerals – making use of the zero – contributes to the new aesthetic equilibrium of this watch.
