Abstract
A skeleton watch includes a horological movement housed in a watch case, the horological movement being arranged to rotate at least one hand, the horological movement being covered by a dial, and the dial being disposed between the horological movement and the at least one hand. The dial includes a photochromic plate so that the horological movement is visible when the photochromic plate is exposed to an amount of UV radiation below a first threshold value and the horological movement is masked when the photochromic plate is exposed to an amount of UV radiation above a second threshold value.
