Chronometers Are The Best Timekeeping Devices in the World. So What Exactly Are They?

Not all watches are created equal, and because of that, not all watches are named equally, either A watch that's really excellent at its job-you know, keeping down-to-the-second time-is known as a chronometer The COSC, founded in 1973, has taken it upon itself to test Swiss-made watches for their precision and timekeeping ability with a gauntlet of challenges.

According to the COSC, testing occurs over 15 days and involves putting the watch in a variety of positions and exposing it to different temperatures For brands, the reward for turning a watch over to the COSC and passing its tests is chronometer certification: proof of a spectacular, well-made timepiece These days, highly accurate timekeeping is low on the list of most watch buyers' priorities.

Plus, even the most accurate watches will never come close to the precision available to most people through phones. . Source
