Jeff Bezos, founder of Amazon, announced the start of the construction of a huge mechanical watch with a working life of 10,000 years without human intervention. The chief designer of the giant chronometer is the American engineer and inventor Danny Hillis. Bezos introduced a video from a clock installation site located in the highlands of West Texas. An impressive size mechanism is being assembled at a height of 152.4 meters. The continuous operation of the clock will be supported by the energy received from the change of day and night temperatures, with synchronization by the Sun at noon. \The designers have already assembled several prototypes, however, the announced watches will be the first model that was actually launched. Inventors spent several years developing a place for a watch in a mountain range and manufacturing component parts. The project cost is estimated at 42 million dollars. The design of the watch does not provide for a traditional time display, instead, the device will emit a different sound signal once a year. After starting the hours of work, visitors will be able to familiarize themselves with the mechanism, however, it will be difficult to get to the object: first you will need to drive a few hours by car from the nearest airport, and then go along the footpath of the Sierra Diablo mountain to a height of 600 meters.
