Document source description
This unusual watch has no numbers, it belongs to a type called "montres à tact" or discrete watches. The clever design allows the time to be told by touch alone, feeling the four diamonds on the hour and the quarters, and the pearls that mark the remaining divisions of the twelve hours. The raised arrow, also in diamonds, contrasts with the smooth surrounding enamel, taking the place of watch hands. It was made for Maria Letizia Bonaparte, Napoleon’s mother, who lost her sight as she aged.The case employs a process called guilloché, where subtle but kaleidoscopic effects are created through mechanical means. Geometric shapes are carved into metal by engine turning. The resulting patterns of fine lines are covered with transparent enamel, when light hits them it creates oscillating optic effects.
