    Re: MKII Accuracy Survey and my new Paradive

    I picked up my Nassau from another WUS member back in January.
    After wearing it for a few weeks I thought I would hack it and keep track of the accuracy. Low and behold after about 2 days it was very fast, like +/- 20s/day. This had me concerned so I tried a few different things. Laid it on it's back for a day.. nothing. Crown up, crown down... nothing.
    Then I decided to try something else. I usually take the watch off for bed and lay it on my nightstand Bose radio, right over the speaker. Could this be the problem ???

    Sure enough, I took it off the radio and left it on the table itself to let it run out of PR. A few days later I put the watch on and hacked it about 2 hours after wearing it. Checked the time 48hrs later and voila +3s in 48 hours.

    Lesson learned.

    (facepalm) Um ... yeah!! Speakers have magnets in them. Whatever possessed you to do that... LOL with you, not at you.

    N.B. Those with Qi wireless chargers for phones/tablets, do NOT put your watch on that unless it's a smart watch designed for wireless charging.

    Funny thing is all my other mechanical watches have always been placed on there and never had an issue.
    They all pretty much have the same movement.
    Weird huh.

    No. Mechanical watches are susceptible to magnetizing, some may have better movement protection than others. It doesn't mean it's advisable practice to rest the watch near magnetic components. ;)

    Oh yeah, I agree and now do not place any watches on the radio.

    Re: MKII Accuracy Survey and my new Paradive

    I'll try letting them run out of PR and see if they settle out. The only magnets I'm aware of them being near are magnetic-closure chest flaps on my shirt-jacket. They're fairly strong for small magnets, but I can't imagine strong enough to interfere with the accuracy of the watches.

    Didn't work. Both returned to losing about 9 sec/day. Submitted a ticket through the CS portal.
