Application
This unit applies to work in watch service centres, jewellery and watchmaking stores and kiosks offering watch service and repair. The unit covers the skills required to diagnose faults where the power cell performance has already been tested and its condition is assessed as good or the correct terminal voltage under load but the watch continues to indicate faults or is stopped. Appropriate diagnostic testing procedures are required to identify or determine the faults in a quartz watch and the extent of servicing required. For repair of mechanical faults refer to the appropriate mechanical watch service units. Band: A Unit weight: 2 points |
Prerequisites
Replace watch batteries, capacitors and bands | ||

Required Skills
Required skills |
Required skills include: using testing equipment (e.g. multimeter and quartz timing machines) analysing test results for current consumption and voltage solving problems replacing cells accessing and interpreting manufacturer service or technical guides communicating with relevant personnel replacing watch bands, straps or bracelets |
Required knowledge |
Required knowledge includes: types of quartz watch construction and components function/operating principles of electronic quartz watches types of cells, power sources, capacitors and electronic storage units observation and inspection techniques 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 diagnose faults in 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: select and perform appropriate tests use testing equipment analyse test results determine faults based on test results and visual inspection report most appropriate service procedures. |
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. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Record and document repair process | Record and document repair process may include: accessing manufacturers' technical guides prepare customer written quotation detailing faults recommend most appropriate service procedure estimate of replacement part time spent on procedure |
