Focus
Mechanical alarm striking on a gong, Master Grand Réveil
It owes its pure sound to an original mechanism: the hammer strikes the gong suspended in the lower part of the case, which serves as a resonance chamber.
Moon phases, Master Grand Réveil
On the dial, the moon phase is displayed differently according to the hemisphere and to the position North or South of the Equator.
Ring or vibrate, Master Grand Réveil
The extremely user-friendly alarm features an original characteristic: the choice between an alarm or vibrate mode.
