Hey guys, feels like we are staying around our good friends place while ours is being repaired ...so I need your help. I have a 312 with a seagull st 25 movement. Recently it kept stopping, i would swirl it or hand wind it and it would run for a while , now its stopped completely. Nothing appeared to break.. I spoke with Katt and he said its more economic to just get a new movement but I'm wondering if its easy enough to clean? The balance wheel moves freely, but just doesn't keep moving just rocks back and forth, the rotor spins easily and you can see the gears wind.....help!
