The Balance Watch

In 2005, John Paul Castro of Santa Monica, CA was granted a patent (No. 6,840,665) for what he called the "Balance Watch". From his patent:

A balance watch, a combination of two watches, one measuring hours, the other measuring minutes and/or seconds. Each watch is worn on a separate wrist simultaneously.


Based on the quality of the artwork in his patent, it's apparent he chose not to splurge and hire a professional illustrator.

As far as I know, the balance watch never made it to market. But it would seem easy enough to make your own. Get two identical watches. Remove the minute hand from one, and the hour hand from the other. Then wear them simultaneously on opposite wrists.

In the dim, distant past (early 1970's?), a short student film about the future showed 'watches' on both top and inside of both wrists. Left wrist, top, local time. Left wrist, inside, Interplanetary Standard Time. Right wrist, inside, O2 sensor with readout of how long you might live in that atmosphere. Right wrist, top, combination compass and barometer (this non-intuitive combination is what made me focus on the details and is probably why I remember it). ((Or some such arrangement, I couldn't swear in a court of law about left/right or top/inside orientations.)) I vaguely recall flattened beads on the sides of each wrist, but I can't say if they had a function or were only decorative.

Actually, it appears that the patent had expired in 2009 due to maintenance fees not being paid. So, go ahead and make your own double wristwatch without worry. And maybe make some better drawings for it as well 😊.

Phideaux, any good Boy Sprout knows that to get safely un-lost, he needs to know the direction he's going and whether a storm may be coming. This he can tell from his trusty wrist compass-barometer. He knows the time from the angle of the sun or the visible constellations.
