Automatic:
Automatic winding means that the spring of the movement is wound by the motion of the wrist. The movement has a power reserve of 70 hours. A new generation automatic watch is equipped with a manual winding mechanism, meaning that when the watch has completely stopped, the spring can be manually wound by turning the crown.
LumiBrite:
LumiBrite is a luminous paint that is completely harmless to humans and the environment. The substance contains no radioactive components. LumiBrite absorbs the energy from sunlight and artificial light within a short time and emits light in the dark.
