Application
This unit of competency defines the skills and knowledge required to diagnose and service micro-mechanisms of clocks and watches, including the procurement and fitting of replacement parts, adjustment and checking to achieve timekeeping and water resistance of completed timepieces to specification.
Where the manufacturing of parts is required appropriate machining units should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
