Disc

A disc is a flat and thin component used in a watch mechanism to display the time or additional functions such as a calendar, moon phase, and other complications. It carries the indicators that are sequentially displayed through an aperture on the watch dial.


The disc is mounted on the central shaft of the watch and is connected to a precise mechanism of the watch movement, allowing it to rotate consistently with the advancement or change of functions. The watch disc is considered an important part of the watch design and contributes to the accurate and easy reading of the complications.
