Yesterday I received this Lord Matic, and while I'm in love with the aesthetics, there seems to be a problem. After fully winding it by hand and wearing it a bit, I noticed the second hand would stop seemingly at random, both off and while on my wrist when not very active. A little sudden nudge would get it moving again. I made sure it was running and fully wound when I left it face up overnight and found it still running in the morning but more than an hour behind. When laid on its side opposite the crown it stops after a few minutes. I was laying down with the 12 tilted down and it stopped. I know the 5606 is notorious for having a bad day-date function but this one's quick set works fine. I would open it up, but I can't get the case back off because it says open thru glass. Should I take it to get serviced? Would it need a new main spring or just a service? How much would I have to pay for each of those, on average?
