Notes
Elements and Performance Criteria
1 Determine servicing requirements and liaise with customer
  • 1.1 Follow standard operating procedures (SOPs)
  • 1.2 Comply with work health and safety (WHS) requirements at all times
  • 1.3 Identify high-grade mechanical watch characteristics
  • 1.4 Prepare written quotation and inform customer of watch condition and performance concerns, outlining recommended service procedures to be undertaken to remedy identified faults and accuracy of timekeeping
  • 1.5 Verify and agree on servicing requirements with customer
  • 1.6 Prepare watch for handover
  • 1.7 Record and document repair process
2 Analyse watch performance
  • 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 Use hand tools and equipment in safe and correct manner
  • 2.4 Handle components without damaging or marking
  • 2.5 Assess condition and ability of watch to achieve chronometer performance
