Application

This unit of competency defines the skills and knowledge required to make fine adjustments to high-grade mechanical watches in order to achieve precision timing (chronometer performance).

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

What You'll Learn

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 and safe work practices

identifying high-grade mechanical watch characteristics

liaising with customer and verifying condition and performance

identifying repair costs and preparing written quotation for service/repair

servicing high-grade mechanical watches to achieve original manufacturer timekeeping standards and specifications in an appropriate work environment

using appropriate hand tools and equipment to carry out precision watch timing and adjustments

conducting watch performance testing and longitudinal testing

analysing and interpreting results of watch performance testing and adjusting and rectifying errors in watch oscillating system

conducting dynamic poising adjustment of balance wheel

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 high-grade mechanical watches by brand and complications

characteristics of high-grade mechanical watch movements/components

timekeeping accuracy for chronometers

watch construction and components

oscillator pivot friction and end shake adjustment

positional error variation adjustments for mechanical watches

balance amplitude/performance/rate variation adjustments for mechanical watches

influence of out-of-poised balance wheel

influence of the escapement on timekeeping

influence of the balance spring design/characteristics on timekeeping

balance spring inspection and adjustment techniques

performance testing procedures for mechanical watches

factors affecting isochronism

workshop procedures for conducting dynamic poising.

Assessment Conditions

Assessors must:

have vocational competency in performing precision watch timing and adjustment 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.
