The know-how and equipment used in chronometric certification activities can be made available to the Swiss watch industry for any type of control related to the rate of timekeeping instruments.
The COSC is able to carry out multiple rate tests on the timekeeping instruments entrusted to it. These tests do not necessarily lead to the title of chronometer, but they can facilitate or even accelerate the development and industrialisation of watches in manufactures.
The owner of the watch brand or the movements submitted bears full responsibility for compliance with the conditions of submission to the COSC.
The Management of the COSC, in collaboration with the applicants, organises the logistics to optimally distribute the productions between the laboratories, taking reasonable account of the needs and wishes of the customers.
