Hi Alan and thanks for your reply. Great customer service from Casio. As your watch has the "Atomic" feature, basically a regular radio update from a very precise time source, it is to be expected that it would keep precise time - as long as it is within radio reception range of the time signal of course. I am more interested in the accuracy of quartz watches that do not have this feature and are left on their own to gain or lose time - hopefully at a very slow, constant and predictable rate which would turn them into mini-chronometers usable anywhere in the world, radio reception or not. I have actually just ordered such a watch - or so I hope - also a Casio G-Shock, model DW5600E-V1, which is probably the simplest G-Shock available. I am assured of its sturdiness - there are wonderful videos on YouTube of the thing being taken out of the freezer, tied to a rotating hand drill to be slapped repeatedly on a wooden board before being dropped into a boiling pot of water for 30 seconds. It still worked after that. I am more curious about its accuracy and predictability and that will take some time to test and tell. I have a feeling it will not be much better than the little old strapless 1984 Casio I already have. -----Original Message----- From: Alan S Sent: Wednesday, February 29, 2012 6:58 PM To: zvidoron@btinternet.com Subject: [NavList] Re: Gary LaPook's Digital Watch Experiment Zvi Doron: On the subject of watch accuracy, I believe I had mentioned this previously, but for whatever it might be worth, my experience with the Casio G Shock "Atomic Watch" runs as follows. I'm on the second such watch, sent the first one back when the resin/plastic band failed after about 5 years of daily wearing. From conversation I had had with Casio, I expected return of my old watch, with a new band. They sent me an entirely new watch, and helped me set it up, as the original one had been. Respecting each of these watches, checking them against NIST/Naval Observatory Time on my computer or at the local public library, I can detect no discrepancy between time shown on the Casio and that obtained from NIST ---------------------------------------------------------------- NavList message boards and member settings: www.fer3.com/NavList Members may optionally receive posts by email.
