Watches certified by the COSC (Official Swiss Chronometer Testing Institute) are rare . This certificate is only issued to timepieces capable of guaranteeing perfect isochronism over a specified period and in defined positions—that is, capable of indicating the time correctly, consistently, and precisely, within the strict limits imposed by an ISO standard . The COSC is an independent Swiss organization that only issues its chronometer certificates after watches have undergone rigorous testing over several days. COSC- certified timepieces represent an elite, a class apart, intended for collectors for whom "Swiss precision" is a daily necessity. The Highlife Automatic COSC model was developed specifically for them.
