This prototype shows detailed graphics and text, not just blocky numbers. It’s the first watch to use a high-resolution version of an E Ink display—its 300 dots per inch far outstrip conventional LCD watches and even most e-readers. Yet its low-power screen and chip let its battery last about two years.

Bulova’s Precisionist watches are among the most accurate in the world, gaining or losing just 10 seconds a year, not the typical 15 a month. They’re regulated by a high-frequency quartz crystal that vibrates 262,144 times a second, eight times the norm. That rate stays ultra-stable because the crystal’s three (instead of two) fork-like prongs resonate off one another to limit the fluctuations that result from changing temperatures.

A collector’s watch that costs 10 grand is worth protecting. And this one can survive a drop from 65 feet, or 24,000 Gs, because four shock-dissipating arms hold its sensitive mechanical gear system in place. They’re filled with an elastic polymer that absorbs large amounts of energy.

The Pulsomatic is one of the few digital watches fueled by your movements, not a battery. A small generator inside converts the mechanical energy of a swinging weight into electrical energy, which it uses to run the quartz timekeeper and LCD. It can store enough power to last 120 days sitting on your dresser.
