CWC G10 Battery

[Xenocide]

I've got a CWC G10 who's battery has recently died. I had the battery replaced and today it stopped running (about 3 weeks from when I had the battery changed). The piece on the top of the picture was on top of the battery and had slid down behind the case shorting it out. Does anyone know the correct order in which the battery and this holding piece should be reassembled? The back of the battery hatch has a sprung loaded piece on it so presumably the other bit should be below the battery?

Any help appreciated.

I managed to find a picture (not mine!).

For any future searchers. Battery goes in first (+ towards you). Then it's the bit in question. spikey bits up with the tangs (on the opposite side) going over the battery below. On mine one was bent out a bit which goes towards to the NW orientation (on my watch). Then it's the hatch. Just be careful when you put the hatch back on, it's a fine thread and would be easy to cross i'd imagine.

The spiky disk ("battery limiting plate") shouldn't be fitted in the CWC G10.

The ETA 955 series movements use it in standard watches to hold the battery in place - it presses angainst the battery and the case back and the tangs act as springs. In the G10 that's what the spring on the battery hatch is for.

It was loose enough to slip down between the movement and the case back because whoever did the batery change has used the wrong cell and tried to space it out using a part that shouldn't be in there. They've fitted a 370 (SR920W), which is "high drain" and 2mm thick, when they should have used a 395 (SR927SW), which is "low drain" and 2.7mm thick.
