For the wooden watches from KERBHOLZ for ladies and men we only use excluding natural wood and obstruct Swiss Parts clockworks of the company RONDA (cal. 762 E). The wooden wristwatches are protected by a sealing ring and special glue against the penetration of splash water. The watch corpus of our watch models consists of wood, the metal plate at the back of the corpus is manufactured out of high-grade steel. All products are protected with a natural varnish against humidity and weather and get darker with the time. Thus they get a nice patina (comparable with leather products) which makes every wood wristwatch unique. All our wooden watches are vegan except the wooden watches with tapes from real, high-quality leather. A wood watch of KERBHOLZ accompanies with lasting effect and is produced ecologically worthwhile.
