Qualification -
Unit of Competency MEM21011A - Service calendar and other dial indication mechanisms for watches
Description This unit of competency covers servicing techniques for watches with different types or combinations of calendar and other dial indications, including date, day, month, year, moonphase, annual calendar, perpetual calendar, retrograde and power reserve indicators.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency applies to dial indication servicing work undertaken by a watch repair tradesperson. This work is often performed in conjunction with major servicing on both mechanical and quartz watches received for repair. This 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 MEM21010A Service watch power generating 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 service calendar and dial indication mechanisms 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:

dismantle, reassemble and lubricate calendar mechanisms

service and fault-find calendar watches

perform inspection and adjustment of calendar change mechanism

synchronise dial indications with calendar change mechanism.

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:

dismantling and reassembling calendar and dial indication mechanism

inspecting and diagnosing faults in calendar and dial indication mechanism

applying correct type and amount of lubrication

testing calendar and dial indication mechanisms, operation and synchronisation

Required knowledge

Required knowledge includes:

types of calendar watches

types of calendar drive mechanism operation

power reserve indicator construction and operation

calendar/dial indications component part names

lubrication techniques for calendar and dial indication mechanisms

fault-finding and inspection techniques of calendar and dial indication mechanisms

occupational health and safety (OHS) regulations and practices

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.

Watch type, calendar construction and dial indication components

Watch type, calendar construction and dial indication components may include:

date indications:

day/date

day/date/month

moon phase and year indicators

annual calendar

perpetual calendar

power reserve indicator

equation of time

Record and document repair

Record and document repair may include:

date and extent of repair

cost of replacement part

time spent on procedure

Workshop tools and equipment

Workshop tools and equipment may include:

hand tools (e.g. tweezers, screwdrivers and eyeglasses)

hand fitting pushers, stakes and presses

Calendar and dial indications drive mechanism

Calendar and dial indications drive mechanism may include:

creeping

semi-instantaneous

instantaneous

retrograde

rapid corrector

Correct fitting and functions

Correct fitting and functions may include:

calendar day and date mechanisms

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.
