When it comes to watches, there are innumerable options to choose from. Prices also vary based on the inbuilt technology such as mechanical movement, quartz movement and automatic movement. While most of these will do their job in everyday life, people looking for perfection may need a watch that has the best accuracy. If you are searching for something similar, here’s a look at some of the most accurate watches in the world.
Zenith Defy – In 2017, Swiss watchmaker Zenith launched the Defy range of watches. Zenith is currently owned by LVMH, one of the leading luxury conglomerates. Zenith’s Defy Lab model is claimed to be the most accurate mechanical watch of all time in the world. To achieve high accuracy, a number of usual components used in mechanical watches were removed. The watch was equipped with a new single-piece monocrystalline silicon oscillator, which powers the high precision of the watch. In terms of accuracy, Defy Lab cannot be wrong by more than 0.3 seconds per day. Another great thing about Defy Lab is that the watch does not need any lubrication.
Calibre 360 Concept Chronograph – This watch was manufactured by TAG Heuer, one of the leading Swiss luxury watchmakers. Calibre 360 Concept Chronograph has high accuracy, as it can display time to around 1/100th of a second. The accuracy is achieved via an advanced balance wheel that can oscillate at 360,000 beats per hour.
Citizen Caliber 0100 – While mechanical watches are the gold standard of luxury, quartz watches can provide really good accuracy. One such example is Citizen Caliber 0100 that was launched in 2019. Its accuracy is rated at around +/- one second per year. Citizen achieved this high level of accuracy by using a uniquely shaped quartz crystal, referred to as the ‘AT cut’. Caliber 0100 is also one of the most stable watches, as it is not impacted by factors such as temperature, radio signals, position changes, etc.
Max Bill Mega – Instead of the conventional quartz crystal, this watch utilizes a radio-controlled quartz. The watch has the ability to continuously update itself based on radio time signals. It has an accuracy of +/- 8 seconds per year. The watch is powered by solar energy and has reserve power of around three years.
Marine chronometers – You may not wear these on your wrist, but it’s still prudent to include marine chronometers in this list. That’s because these chronometers were way ahead of their times. When there was no GPS, these marine chronometers were used to accurately guide ships by determining the exact longitude. Marine chronometers have accuracy of +/- 0.1 second per day. In real life, this accuracy means that the ship will not deviate beyond 1–2 miles (2–3 km) of its destination even after a month at sea.
