Clocks, Watches/Franz Hermle Movement Expected Life


In 1982 we purchased regulator style clock that we love which came with a Franz Hermle 341-020 A 35CM movement (additional number = 112.500).  The original movement lasted 28-years.  Three years ago I paid a clock repair shop to replace the movement and noticed when I got the clock home that the new movement did not feel right when I wound the springs.  Now after 3-years the clock is beginning to only run about 3 days and stop even with a tight spring.  Is there a serial number on each movement?  If so where is it?  Also, once I find the serial number will the year when the movement was manufactured be obvious or will I need to contact Franz Hermle?  I would like to confirm the current movement in my clock is NOT one that was manufactured in 1982.

now the year is letter coded on Hermle --- 1982 would have had "82" stamped on the back

u=  2008  
v= 2009
w= 2010
x=  2011

noticed when I got the clock home that the new movement did not feel right when I wound the springs.    CAN YOU DESCRIBE MORE? "right"?

no serial numbers

might simply need oiling or it is not balance or out of beat--read up here:
-The pendulum assembly begins at the top with a 1" two legged suspension spring pinned to a brass post sticking out of the back of the rear movement plate.
  Next a silver(probably) suspension leader about 5" long that hooks onto the bottom of the suspension spring and passes through the "foot" shaped forked brass piece (and must be in the center of the fork slot and not be rubbing front or back) that connects into the inside of the movement. Newer movements have a horizontal bar that fits in the brass suspension leader slot.
  Lastly the top of the pendulum hooks onto the bottom of this suspension leader. NOW if all is correctly assembled, swinging the pendulum will get it ticking. The sound of the ticking must sound even or balanced on either side. Not over-swinging one side or the other.
  If it is not sounding even, then push with your hand the top third of the pendulum over to the side that has the excessive overswing. You may feel some resistance but gently push a bit more then try the sound of the ticking after swinging the pendulum freely.
  If the sound is not improved in the balance then do more pushing -if it is now sounding like excessive swing in the opposite direction then push the pendulum to the other side till it sounds a pretty even tick. Clock should run then. .(There is a little slip clutch that you are adjusting when you push the "L" shaped foot to either side.)
  There are a hundred things that could be wrong- you have just taken a tour through the repair of what is wrong 98% of the time!
