i wasnt sure where to post this as im seeking a part but it is a very tiny and probably irreplaceable one. basically a few years ago i was attempting to change the batteries in my DW-5400 and DW-5700's respectively, i was able to replace the battery and o-ring gasket on the 5700 no problem but as i was disassembling the module of the 5400 a very tiny spring jumped out and i was never able to find it in my carpet(it had to have been no larger than 1-3mm). so its been sitting disassembled in my desk drawer ever since and id like to get the old girl up and running again, a big problem is not only have i lost the spring but its been so long since it happened im not even exactly sure where the spring came from anymore. so im here hat in hand wondering if anyone has experience with the older modules or even a schematic of the 240 disassembled so i may locate the location of the lost spring, and then ill still of course have to source another spring. im sure this sounds like searching for a needle in a haystack to most of you but if anyone can offer any info pertaining to this it would be greatly appreciated. i would also be willing to send it somewhere to have it repaired if anyone knows of a reputable watch-smith with vintage G-shock expertise. thank you for any help you may be able to offer.
