Here\u2019s a term you may hear tossed around if you spend any time on our blog: COSC certified chronometer<\/em>. What\u2019s any of that mean to you? Well, if you\u2019re a person that prides yourself on being prompt, courteous, and timely, it should mean quite a bit to you. If you rely on your watch to maintain your schedule throughout the day (pulling a phone out of your pocket is so unbecoming), then having a COSC certified chronometer should mean a whole lot to you. The word certified is easy enough, but let\u2019s a closer look at the other two: COSC and chronometer. <\/span><\/p>\n

COSC stands for Contr\u00f4le Officiel Suisse des Chronom\u00e8tres<\/em>, and they are the official Swiss chronometer testing institute. Uncased movements looking to gain chronometer status must pass a series of tests to verify accuracy to within an average of -4\/+6 seconds a day. This means the watch can not lose more than 4 seconds, or gain more than seconds of time each day. To get this average, the movement is tested for 15 days, in 5 different positions, and at 3 different temperatures. While only 3% of Swiss watch production is COSC certified, the brands that do go through the trouble of gaining official chronometer status, often stay well within the -4\/+6 second guidelines.<\/span><\/p>\n

Movements that gain COSC chronometer certification are free to label the achievement on the dial of the watch they are destined to live within. Inspect the dial of the Rolex above<\/a> and you\u2019ll notice the words Superlative Chronometer Officially Certified at 6 o\u2019clock. What that boils down to is this: the watch is going to be accurate enough to keep you on time throughout the day, unless things like timing the half-life of Hydrogen-7 fall within your normal daily activities. <\/span><\/p>\n

The topic of chronometers is a deep rabbit hole, and there are even competitions that revolve around achieving the most accurate mechanical movement. That\u2019s a story for another day. Until then, check out a selection of certified chronometers available on StockX right now. <\/span><\/p>\n
