A full charge is enough for the watch to run for about 6 months.Īnd despite all the technology, these watches are immensely wearable, measuring just 37.5mm in diameter and 9.1mm thick.Ĭitizen is releasing three models and in limited numbers. The Caliber 0100 also employs Citizen's Eco-Drive technology, which means they are powered by light.
Higher vibrational frequencies typically mean more accurate time-keeping. Your typical quartz watch vibrates at a much lower 32,768 Hz. To achieve such high accuracy, the Caliber 0100 uses the more accurate AT cut type crystal oscillators rather than the more typical tuning fork crystal oscillator.Īdditionally, the oscillators in the Caliber 0100 vibrates at a very high frequency of 8.4 MHz - that's 8,388,608Hz. Impressive for a mechanical watch but it has got nothing on the Citizen Caliber 0100. Rolex, a benchmark for mechanical watches, regulate their watches to ☒ seconds per day. Grand Seiko's venerable 9F quartz watches are accurate to ☑0 seconds per year.įor further context, consider that your regular quartz watches are accurate to ☑5 seconds per month. To put this number to context consider these comparisons.Ĭitizen's super accurate Chronomaster watches, as well as Longines' VHP "Very High Precision" watches, are both accurate to ±5 seconds per year. Just how accurate is Citizen Caliber 0100 watch? According to Citizen, the Caliber 0100 is accurate to ☑ second per year. The Apple Watch and certain Bluetooth-enabled Casio watches are more accurate but that's because they sync with an atomic time source. To do that, it has just unveiled its new Caliber 0100 watches, which are the world's most accurate autonomous watches.įirst, let's explain the term "autonomous watch." By this, it means that the watch keeps and tells time on its own accord without syncing to an external source. This Citizen watch is accurate to ± 1 second a yearĬitizen doesn't want you to be late for appointments ever.
