Watchmaking standards

More than 160 watchmaking standards (NIHS, CEN, ISO)* exist and are regularly updated. They cover fields as varied as design, luminescent materials, tests, water-resistance, shock-resistance, anti-magnetism, minimum requirements for the certification of chronometer movements, etc.

All of these standards are available in different formats (full collection, individual standards, extracts from standards). They can be ordered or downloaded here.
