I thought it would be useful to start off by defining what a turret clock is.
From Wikipedia the definition of a turret clock is:-
A turret clock or a public clock is a clock that is larger than a domestic clock and has a mechanism designed to drive a visual time indicator such as dials and or bells as a public amenity. Turret clocks specifically had mechanisms mounted high in a building often a purpose built tower such as churches town halls and other public buildings. Clocks were not referred to as turret clocks by clockmakers until recent times, often old clocks were recognised as turret clocks by their location.
A true turret clock has mechanical and latterly electrical power and therefore sits late in the history of timekeeping.
The Time Workshop collection testifies to the centuries of not only human ingenuity by increasing technical ability, but also of artistic activity. Each clock is a real piece of art, proudly created by companies to be seen by only a small number of people, usually the clock winder and maintainer. The manufacturers found ever increasing ways to make their clocks more accurate and to automatically wind and distribute the time around the building, until the point was reached where it became uneconomical to continue manufacturing mechanical turret clocks.
