Hi guys, been awhile I know, another question, I need a new mainspring for a nice old cylinder fob watch im working on, My springs dimensions are as follows, 1.29mm height x 0.16mm thick x 300 mm length, barrel diameter is 11.31mm On cousins the closest that my untrained brain can find is 1.25 x .115 x 340 now I know these measurements are abit off from my original ones but could someone please tell me what measurements are allowable to change so you can get a spring as close as possible if an exact replacement is not available? I can hazard a guess that I could drop a little on height as I have done so before after a kind member here pointed me in the correct direction for a new spring once before, but before I continue to ask the same quest over and over I need to learn this stuff once and for all so I don't have to keep annoying you all. cheers guys
