One of the criteria for « chronometer » certification is the average daily rate on the first 10 days of testing: from -4 sec to +6 sec., or up to 10 seconds per day. A tolerance which, as such, may appear high, but which, in reality, is the result of an extraordinary requirement.
Each current Breitling (since about 1990 onward) uses this reference numbering system, which gives you COSC indication and caliber identification. The number consists of six characters, which appear on the caseback followed by six more characters which signify case finish, dial color and dial design. This guide has been put together by one of . Watch movements that pass multiple rounds of stringent COSC testing earn the coveted “Chronometer” certification. Every new Breitling watch is a COSC-certified chronometer with maximum average deviations of -4 to + 6 (mechanical) and -/+ .07 seconds (quartz) per day. All Breitling 5X ("Quartz I") and 6X ("Quartz II") calibers whether COSC certified (post 2000) or not (pre-2000) easily maintain COSC quartz specifications (+/- .07 sec/day = +/- 25.5 sec/yr) in actual use.
In the top grade the expected maximum variation in rate between positions is 15 seconds per day and the accuracy is ±4 seconds per day (the movement is adjusted to five positions). And of course for both Sellita and ETA, the chronometer grade movements have to fit the criteria given by the COSC. Breitling always buy the highes quality 'level' which is designed to be produced within COSC tolerances (but is not certified before Breitling take delivery). Other manufacturers buy the same quality level, some of them certify and some don't.The designation, awarded by the Contrôle Officiel Suisse des Chronomètres (COSC), is a marker of the highest standards of watchmaking and a guarantee of accuracy to within -4 to +6 seconds a day for mechanical movements and less than half a second a day for quartz.
Mechanical movements. The OL at the COSC apply the strict test conditions described in the ISO standard or its internal requirements. The results obtained give an exact measurement of the rate of a movement, and of a watch over a given period and attest to its intrinsic precision.
