[time-nuts] The first time nut?
My mention of Alfred Loomis prompted me to get the book out and I found this quote (p. 70 of the hardcover edition): Loomis would remain a time nut for the rest of his life, according to Luis Alvarez, who recalled that Loomis always wore two Accutrons -- one on his right wrist and one on his left wrist. He would check them every day against WWV (the standard frequency broadcasting station of the National Bureau of Standards), and if one was gaining a half second on the other, he would wear it on the outside of his wrist instead of the inside, so that gravity changed the rate of the tuning fork and the two watches tracked each other, and WWV, to within less than a second a day. I know that at least one of us (not me!) was photographed in his younger days wearing one watch on each wrist...

Re: [time-nuts] The first time nut?
No, that is correct. The Accutron has a predictable position error, gaining or loosing a couple of seconds a day depending on whether the tines of the fork are pointing up or down. (gravity effects!). They are calibrated depending on whether it is worn on the inside or outside of the wrist, or whether on the left or right arm. He was simply taking advantage of this phenomenon to make it gain or loose without having to reset it. (on the original 214's there was no hack mechanism to start and stop the movement without taking the battery out). When the watch is worn, it's temperature is maintained at very close to body temperature, in effect it's own oven.

Nope, The author got it right. I have an Accutron 214. It runs fast six up and slow twelve up.

Maybe Tom made a big time error of about 10 years, as it reminds me of myself in the early 70's. Now just a young 62. - Mike B.

OK, I am just too lazy to walk over and check the album. What is a few years off among time-nuts anyway? :) Looks like Glenn's T-shirt says Yamaha, which would be logical. :) Cheers, Magnus ___ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
