Qualification -
Unit of Competency MEM21013A - Service, test and adjust watch escapements
Description This unit of competency covers inspecting watch escapement components and operation, observing and rectifying faults, replacing components and adjusting action to achieve optimum timekeeping performance for a watch escapements e.g. Swiss lever
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency applies to service, testing and adjustment work undertaken by a watch repair tradesperson on watch escapements. Work would normally be undertaken in watch service and repair centres and jewellery stores where service and repairs are offered. This unit has been developed for watch service and repair apprenticeship training and the recognition of trade-level skills in watch servicing and repair. Band: AUnit weight: 4 points
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites MEM21012A Service and repair mechanical watch oscillating systems MEM21009A Inspect, diagnose, adjust and repair mechanical watches MEM21008A Service mechanical watches MEM18001C Use hand tools

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 inspect, adjust and repair watch escapements 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:

identify faults in escapement condition and action

rectify escapement action by replacement and adjustment

correctly service/lubricate escapement

performance test escapements.

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.

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 inspections, diagnosing faults and adjusting lever escapements

replacing and adjusting pallet stones

assessing watch escapement performance and timekeeping

Required knowledge

Required knowledge includes:

watch construction

historic development and common types of escapements

lever escapement function, operation, action, inspection and adjustment

conduct escapement safety tests

techniques for replacement/adjustment of pallet stones

techniques for assessing watch escapement performance/timekeeping

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.

Equipment type and construction

Escapement type and construction may include:

recoil

frictional rest

detached

lever (Swiss or English)

co-axial

dual direct

chronometer (e.g. spring or pivoted detent)

cylinder

pin pallet

verge

duplex

semi-tangential

equidistant

circular

Escapement components and condition

Escapement components and condition may include:

escape wheel

Record and document repair

Record and document repair may include:

extent and date of repair

cost of replacement part

time spent on procedure

Hand tools and equipment

Hand tools and equipment may include:

escapemeter

pallet stone warmer (e.g. spirit lamp and electric warmer)

shellac

banking pin adjusting tools

timing machine

staking tool

watch servicing hand tools (e.g. roller remover, escapement files, burnishers and levers)

Clean and safe work environment

Clean and safe work environment may be specified through:

relevant legislation and regulations

enterprise operating procedures

5S housekeeping related principles and procedures (e.g. sort, straighten, shine, standardise, sustain)

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.
