    How accurate are your g-shocks??

    I was just wondering, how accurate are your g-shocks??

    xx sec./day

    xx sec./week

    xx sec./month

    Do they deviate based on storage, temperature, use/non use?

    Do certain models of g-shocks have different accuracies?

    I'm just a little curious, having just purchased two froggies.

    Some of my DW-6900's and DW-66XX's are terrible. I believe some are over 15 sec's a month. Maybe not bad for a mechanical.

    The recent G-Shock's (and even "The G" models when they don't receive signal) are very accurate. My GW-200 's are very accurate too. Just a few secs a month... Never really measured it. I think my PRG-80 is about the accuratest I have. 3 seconds in two months!

    Cheers,

    Hello Tim:

    My Frogman TC is +2 secs per week. My Raysman is +/- 1 sec per month during the warm weather months and -2 secs per week during winter.

    I have a 5600 series tough solar which is +/- 1 sec per week. Most of my battery powered 5600's and 6900's are within +/- 5 secs per month.

    My 5600 tough solar/waveceptor is accurate to the second.

    In sum, all of my G's are within COSC accuracy guidelines for chronometers.
    Best regards,

    Mike Hogan

    My Frogman TC gains 2 seconds per month. I set it against a clock that updates daily with an atomic signal & find that it has been consistent since I first got it. I don't have to worry about resting position, temperature, etc. that you have to worry about with a mechanical (and this year in New England we've had some pretty bizzare temperature swings). The watch just keeps on ticking accurately away. Pretty hard to find a fault with a tank that's always dead on (and recharges itself as well!) Hope your Frogs treat you as well.

    Mike,

    I was curious about this, so I looked it up. The Chronometer standard is actually about 2 sec/mo at room temperature, and I think the COSC page is saying that watches need to be temperature compensated for the COSC to even bother testing them. So none of our Gs qualify.

    COSC is for snobs, though. :)

    Since I got my Frogman, about 9 days ago, it has only gained 1 second.

    I have g shocks since mid 80s. Without never keeping any numbers I noticed that age has negative effect on accuracy. Saying that I am not sure if is result of more accurate modern modules or just modules increase deviation with age.:-S

    My Frog (200) gains about 2-3 seconds every 2 weeks. My G 2300B is close to that. I set mine against the atomic clock signal in the US.

    Hello Pete:

    I stand corrected (bows low in humility) regarding COSC standards. But I do take issue with being labelled as a "snob." I own two Omegas and a Tag Heuer that are all COSC chronometers. I don't feel that I'm a snob, only someone who enjoys fine timepieces, including G-Shock.

    Please, think before you assign labels to people.

    I never really check mine and only reset the time for winter/summer. Just checked the Riseman on my wrist against the atomic clock and it's 30 seconds fast. 10 weeks since I changed the battery.
