So was trying to fix a dw 003 and did the old problem of catching the alarm spring and it made a jump to freedom I did find it after a search of half hour or so, What happens if you can't find it .. well seems like their's three options are available ( maybe be more please add if you have any ideas )
1) buy a none working watch same model for it
2) make one ( bit hard if you do not have the tools for it
3) find a spring of the same size and materal .. my favorite ..
Lets talk through number 3) for now as 1) is self explanatory and 2) would really need a thread of it's own now, Sjors did a thread on making one over the road so it is possible but has very mixed result with them and he had the tools to do it as well.
So find a spring sounds easy but they are very small my tip is look for spring bars from small watches say as the spring bar is like under 5cm long don't know the diameter of it off the top of my head probably half a cm or less probably less, so the smallest you can get there are spring bars for watches that come in 6cm and the like so my tip is carefully pull the end off the spring bar and removed the spring in side and if you have got a thin spring bar then the spring might just fit.
It could take several goes to find the right one but will work if you find the right size, or if you are brave once cut to length you could always strip the module down and drill the hole larger have seen it done several times on youtube with good results
As always Ismy
