The master watchmaker Božo Godnik (*1946) has been around watches since his childhood because his father was also a famous local watchmaker.

Later he continued his career in the watchmaking department of Zlatarna Celje, where he specialised in the making of wall clocks, which were very popular in the 1970s and 80s.
