Professional Quartz Sport Watch For Men



quartz is a collective term describing watch movements that combine 
a self-winding rotor mechanism (as used in automatic mechanical 
watches) to generate electricity with a piezoelectric quartz crystal 
as its timing element. Such movements aim to provide the advantages 
of quartz without the environmental impact of batteries. Several
manufacturers employ this technique.
