Application

This unit of competency defines the skills and knowledge required to service mechanical watches, including movements, sub-assemblies and components. It covers common servicing requirements for mechanical watches undertaken by all watch repairers.

Where work beyond normal servicing requirements is required unit MEM21009 Inspect, diagnose, adjust and repair mechanical watches should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

  • 1.2 Comply with work health and safety (WHS) requirements at all times
  • 1.3 Identify watch type, functions, construction and components
  • 1.4 Carry out pre-repair tests to verify water resistance, as required
  • 1.5 Prepare written quotation and inform customer of watch condition, completeness and performance concerns
  • 1.6 Outline recommended service procedures to be undertaken to remedy identified faults
  • 1.7 Verify and agree on servicing requirements with customer
  • 1.8 Prepare watch for handover
  • 1.9 Record and document repair process

2. Disassemble watch, case and movement components for servicing

  • 2.1 Establish an appropriate clean and safe work environment
  • 2.2 Select and use appropriate personal protective equipment (PPE) in accordance with SOPs
  • 2.3 Open and close watch cases
  • 2.4 Use hand tools and equipment in safe and correct manner
  • 2.5 Remove case components and movement sub-assemblies in correct sequence without damaging or marking
  • 2.6 Verify condition of case gaskets and replace, as required
  • 2.7 Clean watch case and band, as required

3. Service watch case, movement, sub-assemblies and components

  • 3.1 Inspect condition of movement, sub-assemblies and case components
  • 3.2 Confirm servicing requirements
  • 3.3 Replace faulty or worn component parts/movement, sub-assemblies or case
  • 3.4 Select appropriate cleaning methods and clean components
  • 3.5 Inspect watch case and components for cleanliness and rectify imperfections and faults

4. Reassemble watch, movement and case components

  • 4.1 Reassemble watch movement and case components according to manufacturer specifications
  • 4.2 Assemble motion work and verify and adjust hand setting tension
  • 4.3 Check and adjust component operation and watch functioning
  • 4.4 Lubricate components and sub-assemblies according to manufacturer specification
  • 4.5 Apply watch assembly inspections and precautions

5. Test and adjust watch function and performance

  • 5.1 Verify function of watch movement and sub-assemblies
  • 5.2 Correctly set up and operate mechanical watch timing machine and interpret readings
  • 5.3 Verify watch performance and rate testing and adjust according to manufacturer specifications, as required

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying various mechanical watches by function, escapement and quality

liaising with customer, verifying condition and performance and identifying repair costs

dismantling watch case and movement components for servicing in an appropriate work environment

inspecting condition of case components and movement sub-assemblies for originality of components, corrosion, cleanliness and wear

servicing watch case, movement, sub-assemblies by replacing faulty or worn component parts and selecting appropriate cleaning method

using appropriate hand tools and equipment in carrying out service in a clean and safe work environment

reassembling watch, movement and case components and verifying and adjusting hand setting tension

applying correct amount and type of lubrication in accordance with manufacturers’ specifications

undertaking function and watch performance and rating tests

recording and documenting repairs.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

types of mechanical watches by function, escapement and quality

function and operating principles of mechanical watches

component parts of a mechanical watch mechanism

manufacturer specification and tolerances for lubrication, performance and time keeping

dismantling/reassembling techniques of watch movements according to procedures and manufacturer guidelines

watch cleaning methods

techniques for servicing mechanical watches

band construction and components.

Assessment Conditions

Assessors must:

have vocational competency in servicing mechanical watches at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Foundation Skills
