REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Required skills include:

• diagnosing and fault-finding quartz analog and digital watches
• dismantling and assembling quartz watch digital modules, movements, gear trains and sub-assemblies
• applying correct type and amount of lubrication
• using quartz timing and testing equipment
• communicating effectively
• interpreting manufacturer technical guides

Required knowledge 

Required knowledge includes:

• quartz watch construction and components (i.e. analog, digital and duo displays)
• quartz watch operating principles (e.g. analog and digital)
• quartz watch lubrication techniques
• watch case and band construction and components
• client liaison techniques
• power sources
• power cells, batteries, capacitors and electronic storage units
• occupational health and safety (OHS) regulations and procedures

EVIDENCE GUIDE 

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 service quartz watches 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:

• use correct disassembly/reassembly techniques
• perform watch function and electrical performance testing
• use appropriate watch movement/components cleaning techniques
• apply lubrication techniques.

Context of and specific resources for assessment 

• Assessment may occur on the job or in a simulated working 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.
