  • 1.4 Identify job requirements from specifications, job sheets or work instructions

2. Establish servicing requirements and liaise with customer

  • 2.1 Identify watch case type, functions, construction and components
  • 2.2 Carry out pre-repair tests to verify water-resistance, as required
  • 2.3 Prepare written quotation and inform customer of watch case condition and outline recommended service procedures
  • 2.4 Verify and agree on servicing requirements with customer
  • 2.5 Prepare watch for handover
  • 2.6 Record and document repair process

3. Disassemble watch case and components for servicing

  • 3.1 Establish an appropriate clean and safe work environment
  • 3.2 Open and close watch cases
  • 3.3 Use hand tools and equipment in safe and correct manner
  • 3.4 Remove watch case, sub-assemblies and components in correct sequence without damaging, marking or leaving fingerprints
  • 3.5 Verify condition of case gaskets and replace, as required

4. Repair and refurbish watch case, sub-assemblies and components

  • 4.1 Inspect condition of watch case, including case sub-assemblies and components
  • 4.2 Replace faulty or damaged or worn watch case, sub-assemblies and components
  • 4.3 Select appropriate media for polishing and graining case and band components
  • 4.4 Set up and operate machines and equipment safely for polishing and graining
  • 4.5 Select appropriate case and band cleaning methods
  • 4.6 Inspect watch case for condition and cleanliness and rectify imperfections and faults

5. Reassemble watch case, sub-assemblies and components

  • 5.1 Reassemble and fit watch case, sub-assemblies and components according to manufacturer specifications
  • 5.2 Lubricate watch case, including case sub-assemblies and components and sub-assemblies according to manufacturer specifications
  • 5.3 Verify security, functioning, and operation of watch case, sub-assemblies and components
  • 5.4 Apply watch case assembly inspections and precautions

6. Perform water-resistance testing for watch cases

  • 6.1 Verify and confirm water-resistance rating of watch case
  • 6.2 Identify, set up and operate equipment for water-resistance testing and interpret readings
  • 6.3 Verify watch case performance and repair or replace components and gaskets, as required, to industry standards

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

liaising with customer and verifying condition and performance, identifying repair costs and recording and documenting service/repair process

servicing, inspecting, repairing and replacing watch case components in an appropriate work environment

selecting and using appropriate workshop tools, equipment and media for watch case servicing, polishing and graining

determining and conducting appropriate tests for water-resistant watches

safely cleaning watch cases and bands.

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 construction of watch cases by style, design, material and quality

types of watch glass materials, construction and fitting procedures, including use of adhesives, as required

types of crown construction by style, design, material and quality

types of case gasket materials and construction fitting procedures

types of crown styles, materials and construction

types of pushbutton construction

standards for water-resistance ratings

standards for water-resistance testing methods

procedures for testing water-resistant and divers watches

function and operating principles for water-resistance testing

tools and equipment for servicing watch cases and components

watch case cleaning methods

types of band construction, components and materials.

Assessment Conditions

Assessors must:

have vocational competency in performing watch case servicing, repair and refurbishment 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.
