Thousands of years ago, Pharoahs kept track of time using hydro-mechanical devices. Now, modern day engineers have invented the means to incorporate this concept into a one-of-a-kind wristwatch. Each watch dial has two flexible reservoirs that are attached to a capillary. One reservoir contains fluorescent liquid, the other clear liquid. Repulsive forces keep the two separate. Daily, the timekeeping liquid advances, and later, mysteriously reverses.
