I hope someboday can confirm something for me about a 2688 module;
During some work on the watch I think I lost a small spring.
I think there are supposed to be four internal springs that are used as electrical contacts against the back cover.
In the attached photo I have circled the four spring positions in yellow. I have noted the position I think should have a spring. While I have not measured this spring it is small, about 1mm in diameter and maybe 6 or 7mm in length.
Can somebody confirm that the the area I am questioning should have a spring in it?
