Frederique Constant Men's Watch FC-303N3NH4

It is not common for watches to be certified by the COSC (Official Swiss Chronometer Testing Institute). This certification is only awarded to timepieces that can guarantee perfect isochronism for a specified time and in specific positions; in other words, their ability to keep accurate, consistent, and precise time within the strict limits imposed by an ISO standard. The COSC is an independent Swiss organization that only issues its chronometer certificates to these timepieces after subjecting them to various tests over several days. COSC-certified timepieces form an elite, a class of their own, intended for collectors for whom "Swiss precision" is a daily necessity. The Highlife Automatic COSC was developed especially for them.
