Qualification -
Unit of Competency MEM21001A - Replace watch batteries, capacitors and bands
Description This unit of competetency covers identifying with customers the battery or capacitor replacement need and/or the repair or replacement of bands. This unit also includes conducting any required water-resistance testing.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency applies to the selection and replacement of electronic watch power sources and bands whilst operating in a watch service and repair workshop or jewellery store offering watch service and repair with access to the appropriate equipment. Applications may also be found in kiosks offering jewellery, key cutting, watch service and repair services.Some knowledge of watch glasses, gasket and other component removal procedures is required. However, this unit does not cover specific replacement procedures. Testing functions relate only to the measurement of voltage, consumption and resistance, and checking for case integrity. For example, when power cells are replaced, it is necessary to establish circuit performance by electrical testing and case integrity by water-resistance testing.To perform additional servicing of watch cases MEM21003A Perform watch case servicing, repair and refurbishment should be selected. Band: AUnit weight: 2 points
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 replace quartz or electronic watch power sources and bands 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:

open and close watches without causing damage to watch or movement

confirm watch movement's performance

select correct replacement power sources for watch type and functions

confirm watch case condition and water-resistance.

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.
