Well it happen after my visit to the hospital for a MPI scan and I forgot to take my watch off. A day later my watch is running 4 mins slow consistently. Thinking that could it be magnetized? I soon proceed to my regular watch maker and have the watch inspect but he concluded that the watch is running very accurate based on the time grapher and no further adjustments is needed. Any input will be great cheers.
Happy to hear that the scan was good. Did you not notice that it was four minutes slow until the following day? Could it be that the scan affected the watch and made it run slow or possibly stop during the scan but then had no long term effect once it was over?
I have been monitoring it since then and true enough after about 9 to 10 hours later when I check the time against my iphone it was 3 mins slower. According to my watch marker the watch wouldn't have magnetized as it's not running much faster.
