Thisword "timesuck" just took on a whole new meaning.
The outflow clepsydra was a timekeeping device used in China as long ago as the Shang Dynasty (c. 1600 c. 1050 BC), and certainly by the Zhou Dynasty (1122 256 BC).
Scientists seeking to provide a mathematical explanation for the phenomenon, long noticed by travelers, built a model that mimics the body's timekeeping cells, using factors like light sensitivity, the brightness of the light, and how much people's internal clocks are "skewed" from real time an offset that can be as long as 1 hour.
The fenjaan was the most accurate and commonly used timekeeping device for calculating the amount or the time that a farmer must take water from a qanat or well for irrigation of the farms, until it was replaced by more accurate current clock.

It is not nuclear-powered, but simply a timekeeping device that uses the regular vibrations of a specific atom to keep time in somewhat the same way that a clock pendulum's movements mark the passage of time.
What's more, as luxury buyers reach for goods they consider to be expertly hand-crafted and authentically tied to a "real" heritage, these diamond houses are vying to prove their mettle in the modern timekeeping pantheon by using mechanical movement rather than quartz in their timepieces and by producing that movement completely in-house.
