Unbelievable accuracy from a walmart watch
It reminds me of a friend in the early Eighties planning a single handed to
Hawaii. He agonised over the cost of a precision timepiece. He bought two cheap digital wris****ches with one hidden as a backup. They were perfectly adequate for his navigation to and from. GPS was just a thought and out of the question for the small sailor. Randy "Ignoramus30509" wrote in message .. . A week ago I posted a surprised message about a $6 watch from walmart that seemed to be accurate. I have a little more data now. About 2 weeks ago, I set this watch very accurately to time that is kept by syncronizing with an NTP server (atomic clock), to the second. Today I checked time again whiel trying to be very good at catching the right moment. I typed "date" and pressed ENTER just as the arm of the watch passed :00:00. The result is that the watch is not even by one second off!!! Obviously, there are limits to my own precision in how I pressed the return key right when the watch ticked :00, plus the OS delay in starting "date", but in any case I could not detect any difference. I find it rather amazing, really. The watch is a quartz watch with hands, "water resistant". i |

Randy as a pilot it never fails to amaze me the expensive watches that newbie pilots get sucked into buying. all full of subsidiary dials and as hard as hell to read quickly. this quartz technology is wonderful stuff. for under $30 you can buy a dead accurate easily read analog face watch that keeps time to a second a day. I wear two when flying, one set to either takeoff timezone or destination timezone and one set to zulu (GMT). I use two plastic case lumibright lorus watches, have had then in use for nearly 8 years now, never once found them deficient or inaccurate. I tip my hat to Seiko in japan. they are truely wonderful machinists. Stealth Pilot Australia |
