System for fixing the crystal (1) of an underwater watch. This system is composed of a set of moving arms (4,5) anchored to the watch case (2) and capable of assuming two positions, an open position and a closed position. In the latter position, the arms (4,5) form a bezel for fixing the crystal (1) to the closing plane of the case. When the watch needs to be opened, for example for maintenance, the arms do not need to be removed from the watch, with evident advantages in terms of handling the watch. |
