| - How long is a chronometer title valid ? |
The title of chronometer can be compared to a diploma from a specialized school. At a given time of his life, a candidate has proven, thanks to an exam, that he had met with the performances criteria providing him with that title.
In the same way as for a graduate, this title has been granted to him for his entire life, although his performances may slightly get altered within the years.
|
| - How long does the COSC store the results of his analyses ? |
Results linked to a chronometer are stored for 5 years, from the end of the tests onwards. Beyond this period of time, no further information can be delivered.
|
| - Why is a chronometer more expensive than a non certified watch ? |
| The control itself charged by the COSC is moderate. However, as for the driving licence, it is not the exam itself which proves to be expensive but all what was invested in it to success. |
|
|
Concerning the chronometer, production, movement assembly to meet with the prerequisite precision criteria require more care and time. Therefore the quality itself of the product justifies its price.
|
| - Can a non-certified watch meet the precision criteria of a chronometer ? |
No, as the components of a chronometer are of a better quality and the care granted to its assembly and its setting cannot be compared.
|
| - The COSC Laboratories are SCS accredited, what does it mean ? |
| The COSC labs are up to a Quality Manual (according to the norm ISO 17025) which content and application are supervised by SAS (Swiss Accreditation Service). They are regularly submitted to control audits. |
