Hi there. I'm new to watchmaking and tinkering with watches and have disassembled some cheap mechanical and quartz movements (non or partial runners )to just practise using the commons tools of the trade including tweezers, loupes, microscope and screwdrivers etc. I have a Seagull 3600 ETA clone and will be buying three or four more so at least I'm working with movements that are functional when purchased. In the meantime, I'm working on reassembling ( the difficult part!) these junk movements and would like some help when I come across any hurdles that I can't overcome. I know some will have cheap mechanisms and often have no or low jewels if mechanical and were originally made to be thrown away when they malfunction but I still feel looking at them and seeing what's different and what's similar with better movements will help me get a better understanding of how the mechanism works, how it disassembles and more importantly improved any manual dexterity at an affordable cost. This cheap no jewel movement is virtually disassembled although I have a couple of hurdles to complete it and would like some input. I had trouble getting the ratchet wheel off and the was just spinning ( I ended up holding the wheel cogs with my fingers/ held with pegwood and it allowed me to screw it off). Now as I look at the barrel with the mainspring their is a wheel below it that's attached( see photo) What wheel is that? Is that permanently attached? The second issue is at the beginning I disassembled the hour wheel,the shim and the canon pinion ( see photo)but at the end of disassembly the other side of the movement has the centre wheel and still a brass cover on the hour hand/ dial side.( See photo) Any ideas how to remove it as seems stiff. Do I pull the brass cover off from the dial side and then the centre wheel will fall out or something else? Don't want to break anything Tweezers may not be strong enough. Presto tool? Pliers? Thanks in advance .
