The people at Hoptroff have created the Hoptroff No. 10 movement, which is the world's first atomic-powered pocket watch. The London based manufacturer has indeed created a quantum leap in terms of movements. The Hoptroff No. 10 has within it's heart a highly accurate atomic clock. This is not a radio-receiving movement but an actual atomic clock.
The Hoptroff No. 10 has a caesium gas chamber inside a temperature controlled oven with a laser to excite the atoms and a microwave resonator to measure their atomic transitions in order to measure time. The atomic physics package is supplied by Symmetricom, a US Department of Defense supplier.
The watch will feature a number of complications, all marine associated. The watch can be used for marine navigation. Best of all, the watch will be accurate to 1.5 seconds per thousand years. The watch comes in at 82 mm in diameter and is 25 mm thick.
The final watch is expected to be revealed in this years Salon QP and only 12 will be manufactured initially.
The watch... or rather the movement.
