    Just an update. I've had some communication with James. It seems the issue may have been my watch winder. Since storing them in my watch box and wearing them in rotation, they seem to be improving. Since 2/10, they averaged a loss of 4-6 sec/day. On 2/12, the Nassau lost 16 sec, but improved to -6 sec the next day. Over the past two days, it has gained 1 and 0 sec! I'm going to monitor them for maybe another week to get a better picture, so they may get sent in for an adjustment. All in all, I've had a great experience with James/MK II Customer Service.

    Re: MKII Accuracy Survey

    Were you letting it wind down and stopping in the box, or just resting for 12 hrs or more without winding?

    MKII Accuracy Survey

    Well, after an inexplicable jump off my wrist into a bathtub next to me, I thought my Nassau would need regulation, maybe repair.

    Put it on the winder next to its big brother, synced them both to the USNO time widget at 1134 on 8-11. Here they are 72 hours later.




    As you can see, the Kingston is, after almost 3 years of off and on wear keeping reliable time, about +2/day. The Nassau is only about a second behind it per day. Will return it to daily wear shortly (taking a little vacation with Graywater #13).

    QED: the movements inside the Mk II divers are well protected, and remain really accurate (COSCish standard). Semper fidelis to Mk II.

    Re: MKII Accuracy Survey

    ^nice results

    My 369-Nassau has been such a remarkable timekeeper that i rarely remember the last time i set it.

    I am at +1s per day .... one freaking second. I wear it most days and set it in the drawer of my nightstand at night. On days i don't wear it, its in a winder.

    Re: MKII Accuracy Survey

    After getting my Nassau demagnetized, it's running +1.6 per day (over 7 days).

    Re: MKII Accuracy Survey

    I've been paying more attention recently to the accuracy of my Nassau and was a little worried about losing a full minute (sometimes more) over the course of a month. I haven't yet checked to see if it's a magnetic issue, though after perusing this thread it's the likely culprit.
    About a week ago, I started getting in the habit of manually winding my watch every morning in preparation for my next watch purchase (a manual-only piece) and noticed a dramatic improvement in the accuracy; +/- a couple seconds a day. Has anyone else worked in a few manual turns to their automatic movement? I've still got to do some more testing on this piece, but it's a huge relief to see such a dramatic difference.
