Just the other day, I brought this watch to a watchmaker for a battery replacement. He tried to open it by twisting the caseback, assuming it was screw-down. In the process, he broke two of his tools and left a few scratches and nicks on the back, yet it still wouldn’t budge.

To be fair, the caseback does have notches that make it look like a twist-back, so if you didn’t know any better, it’s a reasonable assumption.

At that point, I noticed a small notch on the case. I asked for a screwdriver, gently pried it open myself, and it came off with relative ease. Turns out it wasn’t a screw-down caseback after all.

All in all, quite the experience and I ended up with a free battery replacement and scratched caseback cover.
