Not certain of the model movement3134 about2004? serial201D2021
The rechargeable battery in mine finally failed, I was able to get a replacement and following a video I took the watch back off very carefully and replaced it but as I was reassembling it, I found a small silver spring that I do not recall seeing when I removed the back. The three gold springs are in place and undisturbed, I have no idea where this fourth silver spring came from, I see no obvious location or hole in the silicone sheet. any hints or clues would be appreciated
