Gold hands and faces guarantee good readability
It is essential to be able to read the time from the church tower at any time of day. Gilded hands and faces effortlessly meet this requirement. Gold leaf is visible in any weather and also at night since a small light source from a street light for example is enough to allow the wafer-thin gold leaf to shine. The gold surface on hands and faces reflects like no other material and is, therefore, commonly used on church towers.
An important argument for gold hands and faces is the durability of a gilded surface in outdoor environments. Properly gilded hands and faces last an eternity. Due to the circular movements of the clock hands, birds tend to avoid these “quiet spots” and thus cause minimal mechanical damage with their claws.
