“Reference AQ6021-51E” also doesn’t exactly roll off the tongue. That is going to make discussing these each individually a bit complex for many people. This is the Caliber 0100 watch that contains the Caliber 0100 (cal.0100) movement. For now, I’d like to keep talking about the bigger picture of the Caliber 0100 as a wristwatch and not just a movement.Ĭitizen, for all its careful preparation making a frame to house this beautiful movement, also seemed to forget giving that frame (the watch) a name. Accuracy, mind you, is not a simple matter to achieve, but let’s get back to talking about the movement later. Most watches don’t even list the estimated accuracy of their movements - that’s how little many timepiece makers actually value accuracy these days. Compare that with the best Rolex watch money can buy, which has an advertised accuracy of within two seconds per day (highly impressive when compared with other mechanical watches). In 2018, Citizen only wanted to focus on the movement technology, as it was a major innovation offering accuracy of within one second per year. A year later, in 2019, Citizen finally unveiled the Caliber 0100 (aBlogtoWatch hands-on here). The Calibre 0100 began its public life merely as a movement in a not-to-be-sold pocket watch case in 2018. These values seem to be at play when understanding each aspect of the Calibre 0100, from its visual design to its strengthened titanium case and bracelet. It has been my experience that the Japanese manufacturing mindset values precision, efficiency, performance, and durability, above all else. The timepiece fits so well in line with values from the culture that created it, one might argue that Citizen’s goal with the Caliber 0100 was to honor Japanese engineering in general. Elegant and well-proportioned, among its other virtues, the Caliber 0100 is a glowing example of Japanese dress-style watch excellence and humility. It actually makes me quite happy that the Citizen Caliber 0100 watch (here as the reference AQ6021-51E) is lovely enough on the outside to get copious compliments from those who have no idea what it contains on the inside. If you are looking for something “Grand Seiko quality” from Japan’s Citizen, then look no further than the very impressive Citizen Caliber 0100 - which also happens to include the world’s most accurate self-contained timepiece movement.
