All Theorema 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 significantly 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. This allows air to circulate between the leather and your skin and helps keep your wrist cooler. Failure to do this will cause your strap to absorb excessive sweat resulting in bad smells and the development of bacteria.

In case of moisture in leather, please let it dry before putting it on. Do not soak in water, but gently dry with cloth.
