The clock's materials are deliberately inexpensive, to discourage looting, and its location (on land Bezos owns) is quite remote; the nearest airport is two hours away and getting to the clock chamber requires hiking up 2,000 feet from the desert floor. It's also designed so that most of its components can be repaired using nothing more than Bronze Age technology and tools.

A clock designed to run for 10,000 years is an hubristic project, of course, but also a quite fascinating one – you can watch the installation video as well as find out more about the clock, and its chances of running for about as long as human civilization has existed, at LongNow.org.
