MEM21013A
Service, test and adjust watch escapements

This unit of competency covers inspecting watch escapement components and operation, observing and rectifying faults, replacing components and adjusting action to achieve optimum timekeeping performance for a watch escapements e.g. Swiss lever

Application

This unit of competency applies to service, testing and adjustment work undertaken by a watch repair tradesperson on watch escapements. Work would normally be undertaken in watch service and repair centres and jewellery stores where service and repairs are offered.

This unit has been developed for watch service and repair apprenticeship training and the recognition of trade-level skills in watch servicing and repair.

Required Skills

Required skills

Required skills include:

performing inspections, diagnosing faults and adjusting lever escapements

replacing and adjusting pallet stones

assessing watch escapement performance and timekeeping

Required knowledge

Required knowledge includes:

watch construction

historic development and common types of escapements

lever escapement function, operation, action, inspection and adjustment

conduct escapement safety tests

techniques for replacement/adjustment of pallet stones

techniques for assessing watch escapement performance/timekeeping

occupational health and safety (OHS) regulations and procedures

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to inspect, adjust and repair watch escapements to industry standards, manufacturer specifications and in accordance with safety regulations and procedures.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently:

identify faults in escapement condition and action

rectify escapement action by replacement and adjustment

correctly service/lubricate escapement

performance test escapements.

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
