Unit Descriptor
Unit descriptor |
This unit of competency covers servicing techniques for inspecting, diagnosing faults and adjusting common clock escapements (e.g. deadbeat, recoil, cylinder and verge). It also covers techniques for servicing and replacement of different types of oscillating systems, including compound and compensating pendulums, torsional pendulum (e.g. 400 day and Atmos clocks) and platform escapement and floating balances. |
Application of the Unit
Application of the unit |
This unit of competency applies to servicing work on clock escapements and oscillating systems undertaken in clock service and repair workshops. This unit has been developed for watch and clock service and repair apprenticeship training and the recognition of trade-level skills in watch and clock servicing and repair. Band: A Unit weight: 4 points |
