A self-contained Cesium Atomic Clock has been integrated into a wristwatch by US-based watch company Bathys Hawaii

Using state-of-the-art technology derived from the US military, watchmaker Dr. John Patterson and engineer George Talbot have successfully demonstrated a working prototype cesium atomic wrist watch capable of accuracy to 1 second in 1000 years. The new watch is called the “Cesium 133”, named for the most stable isotope of the element.

“The technology found in this watch is something even a decade ago no one could imagine existing in such a small package” says Dr. Patterson. “Within a single chip there is a laser, a heater, a sealed cavity of cesium gas, a microwave filter and a photodiode detector. Using the exact same principle of counting hyperfine lines of excited cesium 133 atoms used by the National Institute of Standards and Technology (NIST), our watch is able to achieve unprecedented levels of accuracy; on the order of 1 second per thousand years”.

The prototype watch created by Patterson and Talbot is powered by rechargeable lithium batteries and the time is displayed on a traditional analog dial with a moonphase indicator. The watch at 60mm x 50mm x 23mm. Before the watch enters production, Patterson anticipates reducing the size and increasing the battery life.

Bathys Hawaii is a small boutique watch company that was founded in 2005 by Dr. John Patterson. The firm specializes in timepieces designed for diving, exploration and extreme environments. The watches are designed in Hawaii and manufactured in Switzerland. Their website is http://www.bathyshawaii.com

For an individual, this appears to be an over-kill. The ability to notice a 1/100th change in time is impossible and such instruments can be considered useless. The only use for such a time piece is bragging rights.
