Eta G10 Stem Crown Removal

Removing the crown and stem on the ETA G10 and ETA G15 series of quartz chronograph movements is fairly straightforward, but there are a few important notes that aren’t always mentioned.

Step 1:

Firstly, when looking at the movement, there is a hole near the crown with an arrow pointing to it.

This hole leads to the detent button or setting lever that prevents the stem from pulling all the way out when setting the time/date.

Step 2:

Pull the crown out one click to date setting mode.

Step 3:

Press your tool of choice gently in the hole while pulling the crown/stem out of the movement/case.

“Tool of choice” is used here because there are different tools that can be used, although most folks will interpret that as tweezers. Just bear in mind that some tweezers won’t work…

This is because while the tip of the tweezers is narrow enough to fit in the hole, most tweezers will widen too much before the tip can reach the detent. It’s important to note how much distance is between the metal cover on the movement to where the stem is.

For this reason, you can try a 0.6mm watchmakers screwdriver (silver).

A tool like this is long and narrow enough to reach the detent.
