Cesium 133. Not the most beautiful watch but certainly accurate.

By utilizing a genuine internal cesium atomic clock, the Cesium 133 is the first atomic wristwatch; accurate to 1 sec in 1000 years. It’s a kickstarter project. The watch will cost approximately around 6000 US dollar.

The Cesium 133 – the world’s first wristwatch powered by a cesium-based oscillator . This revolutionary technology uses a chip-scale atomic clock (CSAC) to precisely divide a second into exactly 9,192,631,770 vibrations  of the cesium 133 atom – in fact this is the scientific definition of a second by the International System of Units (SI).

The goal is to produce a small, limited edition run of 6-10 watches as a way of bringing this new technology to market.

Powered by a rechargeable lithium battery and capable of running up to 36 hours (depending on operating mode) the prototype uses a traditional analog dial display that features hours, minutes, seconds, date and current moonphase. However behind that traditional dial is where everything “traditional” ends: while the micromotor and gear train is retained, a unique interface between the CSAC chip and the Ronda 509 watch movement was designed in-house, as were the COM port, charging circuitry and micro-connectors. Separate status LEDs indicate power on/off, charging status and CSAC chip “lock”. Once powered up, the CSAC chip takes approximately 30 sec to achieve lock – at this point it begins to transmit its highly-accurate 1 pulse per second signal – this is then conveyed to the watch hands via a switchable circuit so one can precisely set the time. Once set, the CSAC chip can operate for years – providing timing accuracy only surpassed by large dedicated atomic clocks.

A Little Background.

The owner of Bathys Hawaii, Dr. John Patterson, is an avid fan of technology – especially military and scientific research tech. He is constantly searching for new technologies that might be incorporated into timepieces of the future. During conversations with a friend who studies deep sea oil exploration, the existence of the chip scale atomic clock was mentioned and this fascinated him. Could this chip be used to create an atomic wristwatch? Had anyone already done this? What were the technical challenges to making this into the world’s most accurate wristwatch? He wanted to begin as soon as possible to answer these questions.
