Manufacture watch and clock components

Assessment tool

Version 1.0
Issue Date: May 2024


This unit of competency applies to the manufacture of replacement watch or clock components in a watch or clock repair and service centre. It applies when undertaking servicing and repair of watches and clocks and replacement parts are not available and there is a need to make a suitable replacement.

This unit has been developed for watch and clock service and repair apprenticeship training and the recognition of trade-level skills in watch and clock servicing and repair. It may apply to post-trade training if not completed as part of a trade qualification.

Band: B

Unit weight: 6 points

This unit of competency covers manufacturing watch and clock components using a range of general and specialist machines and engineering techniques.

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 manufacture clock and watch components 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:

manufacture, finish and fit replacement watch or clock components to original tolerances

select and use appropriate hand tools

use lathes and accessories to turn watch and clock components

perform milling operations using indexing and milling attachments on the lathe or bench-mounted milling machine to dimension and tolerances.

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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

performing lathe operations on a watch and clockmaker's lathe

performing milling operations using milling attachment on a watch and clockmaker's lathe or a bench mill

selecting and preparing cutting tools

planning of project sequence

preparing working drawings of parts

interpreting watch and clock drawings, manuals and other documentation that provide information of part design and tolerances

measuring tolerances

Required knowledge

Required knowledge includes:

typical materials used in watch and clock making

types of watch and clockmakers' lathes and attachments

lathe accessories and tooling

setting up and safe operation of watch and clockmakers' lathes and attachments

milling procedures

occupational health and safety (OHS) regulations and procedures

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.

Replacement parts

Replacement parts may include:

wheels and pinions

arbors and pivots

click springs

ratchet wheel

setting lever springs

Record and document repair

Record and document repair may include:

date and extent of repair

cost of replacement part

time spent on procedure

Working drawings

Working drawings may include:

sketch or illustration by hand, including dimensions

Appropriate chuck

Appropriate chuck may include:

collet, three jaw and four jaw

Appropriate cutting tool

Appropriate cutting tool may include:

graver

cutting tool angle

parting off tool

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
