    Re: MKII Accuracy Survey

    FWIW, I've been watching my new Kingston. Setting it to the USNO java atomic clock app.[1] On the winder, it seems to gain about 7 seconds in 5 days (yeah, holy cats that's good). I believe normal wear can effect timing, so I've been wearing it for the past day, off for 6 hours overnight, and it seems to have gained ... nothing, maybe a 1/2 second or so.

    IOW ... "Dayam, Bill, righteous #*@ &%$~ regulation!"

    Day two and ... on the night table (crown up) after being worn most of the day and (drum roll) ... it's barely gained a second. A second in two days, that's within one of the COSC criteria IIRC (there are more I believe). Making this the most accurate automatic I own. I now understand the fervor of the MKII owners club members.

    Re: MKII Accuracy Survey

    Since my magnetization adventure my Sea Fighter has settled down a lot. I'm trying not to wear out the crown tube by hacking it too often, so I decided that since it runs fast, I'd hack it exactly one minute slow, then when it got to be one minute fast, I'd hack it for two minutes again. That way half the time it's actually getting MORE accurate every day, and I don't care much about a minute these days.

    So I hacked it after coming back from a trip to Miami on March 16th since I had to reset it to Central Time. One minute slow. March has 31 days, so I didn't have to touch the crown then. April has 30, so I checked it against time.is on April 30th. Still not a minute fast, so I just rolled the date back without hacking and screwed the crown back in. May has 31 days, but I was starting to run a little fast. It was almost exactly a minute fast on Friday, May 31st, so I went ahead and set it down for the long weekend, then wound it and reset it on Monday.

    So that's 120 seconds gained from March 16th to May 31st, or 76 days, so it's running +1.58s/d for two and a half months.

    For me this is pretty much optimum accuracy. I can hack the watch on the days I need to reset the date and just let it run in the meantime. I'd need a perpetual calendar to get any use out of more accuracy.
    Guys, I really really really do understand that there was a hack and that my password was reset, but I'm about to take a year off from WUS if you can't stop telling me about it every time I log in. With my password. That you reset.

    Well, my Nassau usually runs between +/- 0 and +/-7secs a day, so I'm happy! It lost (or gained, can't remember) around 35 secs in a whole month! It's by far my most accurate watch.

    Not bad when on my wrist for a few days:



    It got a bit worse after a couple of days on the winder. I'd add the pic but I guess WUS doesn't like images shared from Dropbox for some reason.

    Update: Got my $15 ebay demagnetizer (shipped from Egypt of all places), applied it to my Kingston according to the guy's instructions that did the youtube video about de-maging his Orange Monster, and voila! My Kingston is running right at -1sec/day. Win!

    Re: MKII Accuracy Survey

    I just did a two week accuracy test with my Kingston. Wore it everyday and night, taking it off to shower, clean it and change straps.
    Timed off a atomic clock on phone. In two weeks my Kingston gains 73 seconds. That's about 5 seconds a day I guess. Can't really complain with that given the amount of abuse it goes through.

    Re: MKII Accuracy Survey

    Timed over a two week period, my Kingston is within 1 second per day. It's no wonder all my other watches gather dust.
