Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to cases for all types of watches, including non-water and water-resistant watches and all types of case materials. Servicing, repair and refurbishment would normally be carried out in watch service and repair centres and watchmaking stores where repair services are offered.

Band: A

Unit weight: 4 points

This unit of competency covers servicing and repair techniques for watch cases, including replacement techniques for watch glasses, pendants, pushbuttons and correctors, bezels, case backs, gaskets, crowns and bands, straps or bracelets. Also covered is refurbishment techniques for watch case or band by polishing and graining. Additionally, this unit includes standards for water-resistance testing methods and procedures for water-resistant and divers watches.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 perform watch case servicing, repair and refurbishment 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:

service, inspect, repair and/or replace watch case components (e.g. glass, crown, pendants and pushbuttons) to manufacturer specifications

select and use appropriate workshop tools, equipment and media for watch case servicing, polishing and graining

determine and conduct appropriate tests for water-resistant watches

safely clean watch cases and bands (e.g. by machine/hand).

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.
