TS 12623

TS 12623 is a vocational standard for watch repairers and for defining the people who carry out this occupation. Watch repair work sits at the intersection of precision mechanics and, in many modern watches, electronic functions, so the subject naturally involves careful diagnosis, controlled disassembly and reassembly, and the proper use of specialised tools.

Occupation structure and qualification framework

According to the scope, the standard covers the definition and classification of the watch repairer occupation, the characteristics expected of people working in it, and the evaluation of those characteristics. It also addresses the tools, instruments and equipment used in the occupation. In practical terms, this helps distinguish levels of responsibility within the same trade, because watch repair is not only about fixing faults; it also depends on precise measurement, component compatibility and consistent workmanship.

Technical context for watch repair

In general technical terms, watch repair includes inspecting the movement, locating faults, cleaning components, making adjustments and replacing parts when needed. The tools and equipment associated with the trade are intended to support controlled work on very small screws, springs, gears and dial-related components. This standard brings the training and evaluation side of the occupation into a formal vocational framework rather than prescribing the full technical design of every watch system.
