Elements and Performance Criteria

RANGE STATEMENT
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.
Types of chronograph watch mechanisms
Types of chronograph watch mechanisms may include:
types (e.g. application of dial scale indications - tachymeter and telemeter)
chronograph operating systems (e.g. pillar wheel actuated or cam controlled)
features (e.g. minute record, hour record, automatic and split second)
performance characteristics of chronograph watches
Appropriate working environment
Appropriate working environment may include:
adequate lighting and ventilation
clean bench and working area
tools and equipment organised and in good condition
ergonomic seating
Record and document repair
Record and document repair may include:
date and extent of repair
cost of replacement part
time spent on procedure
Dismantling and assembly precautions
Dismantling and assembly precautions may include:
inspection of condition and adjustments of chronograph assembly functions
verification of correct recording system operation (e.g. engagement, depthing, end shake, penetration)
correct selection, application and amount of lubrication for chronograph mechanisms
adjustment of timekeeping performance and balance amplitude during chronograph function
Chronograph components
Chronograph components may include:
operating mechanism (e.g. single and double pusher action)
clutch system for chronograph engagement
transmission (e.g. minute and hour record)
flyback and zeroing
Chronograph action
Chronograph action may include:
start, stop, reset to zero
hand zeroing
indexing minute and hour record
Dial and hand fitting
Dial and hand fitting may include:
hand fitting tools and supports
alignments and sychronisation
Watch performance and rate testing
Watch performance and rate testing may include:
beat error diagnosis and adjustment
rate adjustment/positional errors
amplitude (e.g. chronograph start - maximum variation <40 degrees)
Hand tools and equipment
Hand tools and equipment may include:
movement holders for operating chronograph functions
timing machine
rose cutters
tools for removing chronograph driving wheel
hand staking and fitting tools and supports
case opening and closing tools
Clean and safe work environment
Safe and clean 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)

EVIDENCE GUIDE
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 mechanical chronograph watches 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, assemble and clean chronograph watches using correct techniques and precautions
inspect, fault-find and adjust chronograph mechanisms
perform function and performance testing
perform chronograph dial and hand fitting
select and apply lubricants correctly.
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.
