History
Hoptroff London was founded in 2010 by Richard Hoptroff, a physicist with the original intention of supplying smart mechanical watch movements to the industry. In 2012, the company incorporated Bluetooth Low Energy technology to its watches for the movement and sync with the mobile phones for configuration in order to display internet connected information. Hoptroff London kept the manufacturing in-house to focus on the high precision and innovative complications.
In April 2013, the company unveiled its first atomic timepiece in London, which conceptualized it as a new variety of time regulation devices in clocks and watches, that could be placed alongside the balance spring, quartz crystal and the pendulum. After the launch, the brand gained a reputation for the most accurate watch ever produced and was mentioned in several media outlets, such as New York Times, Engadget, The Telegraph and others. In 2015, Hoptroff London launched a classic quartz watch range with a claim to being the first watchmaker to achieve better than one second per year accuracy in its quartz watches.
Technology
Hoptroff London watches are advertised by the company as "The most accurate timepieces in the world”. Its atomic timepieces use chip scale atomic clock technology, where a small vessel of Caesium 133 is exposed to 130 °C. A laser is used to excite the atoms and a microwave resonator which causes the hyperfine transition frequency of the atoms. The resultant watch after this process has a higher accuracy of 1.5 seconds every thousand years.
However, the technology used its quartz timepieces is still unknown to the public.
Collections
Hoptroff London offers three lines of watches, labeled Classic, Sports and Atomic. The company claims its lines of watches are accurate from fifteen seconds a year to 1.5 seconds per millennium. Its No.10 pocket watch is acknowledged as the most accurate watch in the world.
