Astronomy
Measuring time has always been a challenge for humanity. To overcome this challenge, astronomers and observers from various cultures have come together to find reliable points of reference that can be used under any condition. The Pole Star, Southern Cross, astrolabes, and sextant are some of the markers of cyclical time that have been discovered through human ingenuity, patience, and dedication. These markers are essential for Arnold & Son watchmaking and have become the foundation for its work.

Chronometry
Arnold & Son’s modern watchmaking is characterized by rate accuracy, also known as chronometry. This is the most subtle feature of its movements. Although the tourbillon was patented after John Arnold’s death, it was undoubtedly at the centre of his chronometric research and discussions with his friend Abraham-Louis Breguet. In fact, the latter assembled his first tourbillon on a John Arnold regulator as a tribute to this great watchmaker. Today, the tourbillon has become an essential component of Arnold & Son’s collections.

World time
With ocean navigation, humankind divided up the world and invented longitudes. This was accomplished by comparing local time, determined by observing the sun, to the time at a specific starting point, measured by a highly reliable timepiece. John Arnold was a prominent supplier of chronometers to the Royal Navy. He successfully improved the reliability and simplified the production of these indispensable marine chronometers, to the point where he became a benchmark among great explorers. The indication of multiple time zones is now an integral part of Arnold & Son’s watchmaking identity.
