BradBMW Posted July 24, 2014 Report Share Posted July 24, 2014 Hello all, I need to remove a 1570 movement from a case that was apparently worked on by a Neanderthal. It took a LOT of power to remove the caseback. The 2 clamp screws inside the case won't budge. I can tell a prior "jeweler" didn't know the direction to screw/ unscrew them, because there are scratches on the tops of the screw heads. I do think perhaps I'm using the wrong type of screwdriver. I have a set of jeweler's precision screwdrivers, but the blade was too thick to fit in the slot. I've watched videos online, and the watchmakers seem to use just light pressure to unscrew the clamp screws. Surely someone wouldn't have used loctite?!? Can any of you recommend the proper screwdriver for this? Any other tips? Many thanks, Brad Quote Link to comment Share on other sites More sharing options...
BradBMW Posted July 24, 2014 Author Report Share Posted July 24, 2014 Never mind, got it. Had to grind one of my screwdrivers. Quote Link to comment Share on other sites More sharing options...

alligoat Posted July 25, 2014 Report Share Posted July 25, 2014 Screwdrivers are a constant maintenance item! You have to keep a stone around- keep the tips flat and square and file the sides so that they don't get too fat! Quote Link to comment Share on other sites More sharing options...
