Hello I just bought A Mido watch pre-owned and certified COSC of course it must be a really accurate watch right but at least +/-10second a day worst But this watch run fast like 1- 1.5 minutes a day...from the movement blue screws i see that the watch has never being serviced since it first owner, I want to ask,does this watch need service or this watch got magnetize? Cause it just run fast 1-2 minutes fast and i see many articles say that magnetize watch can run fast to hours.. Thanks

Hi WRT's, I'm new to watch repair but am pretty hooked on the problem solving and the detailed work! I can't stop! but this mystery is killing me; I have a 1946 Mido Multifort with a 816 bumper movement that stops randomly without provocation. When I opened it up, disassembled, then reassembled to test out the power train (without mainspring), everything spins and moves smoothly. So I continue to install the mainspring & bridge, give it a wind, and it runs smoothly --until I mount the bumper winder assembly and it stops. Dismantle, recheck, reassemble and it runs smoothly --this time, until I mount the bumper weight assembly when it stops. ... ...dismantle, recheck, reassemble. And it runs smoothly ( I even got the caseback on!) --until a few minutes later when it mysteriously stops. ... ... ...dismantle, recheck, reassemble but this time without the escapement. I apply a little wind, it spins and whines down. <repeat> it spins and whines down. I apply a little wind a third time but this time it stores the wind and doesn't automatically spin and wind down. So I jiggle the gear train and then suddenly it releases the wind (thank God I was careful not to give it too much wind on the 3rd test!) So I take the face and hands off, check the hour & minute gears and they look fine. Reassemble... Long story short, its all back together and it still stops randomly. --I know something is obstructing the power train but I have no clue where to specifically look (my eyes are still learning to differentiate the minutia). Anyone and everyone, I gladly welcome your ideas. Further, as I received the watch, non-working (it wouldn't even wind; possibly because it was stopped/ obstructed and wound to the fullest), when it does run, it runs fast. We're talking about gaining hours in a day (p.s. no, it didn't run for 24 hours continuously; I just did the math during the minutes that it did run). I'm venturing a guess that this is a separate problem but just to be sure, ...are they related? Thanks in advance, Ray
