  1. I'm trying to release the tension in the mainspring on an Elgin grade 144 pocket watch and unlike my grade 291, this one has a hidden click and the main barrel is tucked underneath a plate. I've looked online and found a single forum post stating I need to push a pin or very small object into a hole underneath the main barrel (which there is one) while simultaneously holding the stem in place to stop it from unwinding all at once. The problem is, I've got a single screwdriver that fits in this pinhole and after poking around in a few directions, it doesn't seem to be releasing the click. I don't know if this is the right hole (it is the only one) that I'm putting it in, if it's supposed to be on a specific angle at insertion, a certain depth, etc. I've attached photos of the side of the movement and a diagram of what I am doing. For what its worth, its a lever set.
  2. Hello, Hi Newbie here with my first attempt at watch repair. I just cleaned and disassembled my speedmaster (model 3513.53) 7750 movement having watched the breitling 7750 youtube videos, studied some walkthroughs and also the ETA assembly sheets but am having some problems re-assembling and getting it functioning. I installed all the (new; complete assembly) mainspring, train gear, the bridge, the ratchet wheel and then check by rotating the ratchet wheel whereupon a little a satisfying whirring noise occurs as all the wheels freely spin indicating that they are correctly installed. I install the (new) pallet fork and the bridge for that and it freely moves. Then I install the balance wheel, carefully and several times now but it doesn't enthusiastically oscillate like I see in all the youtube videos the momen it's installed. If I give it a nudge it moves seemingly freely and the pallet fork/escapement wheel moves back and forth but only for half a second then it stops. So I think there's not enough power from the (new; complete assembly) mainspring (same thing happened with the old mainspring)and give it some winds then inevitably the click spring pings out of the ratchet wheel teeth and unwinds the crown/mainspring rapidly (I have now damaged 2 escapement wheels in the process, snapping off their location pins) One time I physically held the click spring against the ratchet wheel so that it couldn't ping out, wound the watch a few times (maybe 10 turns) and got a few seconds of oscillation from the balance wheel but knew that the moment I stopped holding the click spring it would just ping out again! I notice now on ebay someone is actually selling a 7750 movement but with the click spring actually soldered (!) in place presumably to stop it pinging out like mine! I am trying to persevere and repair this watch myself despite this so joined this forum!!! I've tried assembly about 5 times with this now but can't get past it. Any ideas? Thanks.
