All Pionier leather bands are genuine cow leather styled to the finest standard. 

The leather band is an undisputed asset of the watch; thus, it requires some love and attention. 
We want to advice you that contact with extent moisture, lotions, and other skin care can hasten the aging of your leather band. Due to hygienic reasons a leather band watch should be removed before playing any sports. It is best if taken off at night before sleeping to give the leather some room to breath.
