I have a 2018 manufactured SKX that was running a bit slow so I regulated it by wearing it and checking the time daily. It now runs about plus or minus 4 seconds a day if I wear it constantly, but if I take it off it immediately starts losing time, at the rate of around 15 to 20 seconds a day, even if I only remove it for a few hours. It doesn't matter if I leave dial up, 9 up etc. Any ideas?
