    Re: MKII Accuracy Survey

    In my case I would have to thank mr. Schweitzer for the accuracy :)

    I think it's Bill. Both my Kingston's run similarly. Both very accurate.

    Time for a 4.5 day accuracy test. Dad and I hacked his dated Sub and my Kingston this afternoon while I'm home. Started the hack at 1630 this afternoon, but just now got around to taking a pic.



    If it looks a second or two off, I think it is just the angle of the camera, because it looks hacked to me.

    We'll see what happens, but I have high hopes!

    First off, I am no accuracy freak. It's one reason I wear a mechanical wstch.

    Funny thing here, though. My Kingston has been running a few seconds slow /24 hrrs since I got it in February. For that reason I always leave it dial up on my nightstand.

    The other day I looked down and noticed it was a minute or two ahead of another clock. Checked Time.is, and sure enough it is now running about +5 sec/24hrs.

    I'm going to try leaving it crown up for a few nights and see how that affects it.

    As I said, I'm no accuracy freak, and I'd rather it be a few secs ahead than behind.

    Re: MKII Accuracy Survey

    My only MK II is a custom Seafighter I purchased from Bill in Sept. 2008 . It was regulated in 6 positions . It consistently keeps time +/- 1 second per day . I have an Omega PO and a Seamaster GMT that are as accurate , but when you compare the cost of the Omegas to the MK II , the value you get in the MK II is simply amazing .

    Re: MKII Accuracy Survey

    Hello, All!

    A couple of months ago (time flies when you are having fun...), I started posting accuracy survey results here for my MKII's. In August, I wore my Vantage to work and checked it against a GPS Satellite Clock according to the same methodology I had outlined earlier in posts above (concerning my new Paradive and my Kingston). As I said previously, I work a twelve-hour, seven-day shift, either nights or days from 7 to 7 (or 0700-1900, or 1900-0700). My Vantage is not a custom, it is one of the last forty Mr. Yao made, and at the time this appraisal was done, it was almost a year old.

    On August 19, I hacked the Vantage to the satellite clock after I came on shift.

    I wore the watch normally after that, and did not hand-wind or reset the watch. My normal routine has me wearing the watch for about fifteen hours or so, and then it would rest for the other nine hours or so while I rest.

    I found that the Vantage would end up losing about a half a second during the time that I actually wore it, but it would make up that time while it was resting, so when I returned to work, the time would be within a quarter second of what it was supposed to be, usually just a touch fast. At the end of the shift, about eleven to twelve hours later, it was consistently about a half a second slow.

    At the end of six days and eleven hours it was about a half a second slow.

    That is very good accuracy for a mechanical watch!

    I am very satisfied with these results!!

    Thank You, Bill, for this classic masterpiece, and your care in making it.


    -Best to all, enjoy those MKII's-

    Re: MKII Accuracy Survey

    Update: After hacking to Time.is early in the week, my Kingston is now running +39 Wearing 12-15 hrs/day. Resting crown up at night. It gained 14 sec yesterday alone. Starting to consider sending it in to be regulated.

    Edit: it's worse than I thought. +14/24hrs.

    Re: MKII Accuracy Survey

    During the week, when I wear my Kingston or Vantage to work (sitting at a desk all day), I typically wear my watch for 10-12 hours, it spends the remainder of the 24-hr period resting crown-up. My Kingston consistently loses about 5 seconds a day, and my Vantage will gain about 5 seconds a day.

    Not the most accurate watches I've ever owned, but acceptable for now, and I love them, so they could probably get away with murder. One of these days I'll probably get them regulated, certainly if they get any worse.

    I always keep this reference handy. Sadly it's not helping my Kingston much at the moment.
