Casio diver stiff bezel.

[So]

My son has a cheapo Casio diver on which the bezel tightens up until it won’t move. Then the next day it’s fine.

It’s been back to Casio and they can find no fault. It came back fine. Then it went wrong the next day.

Any ideas chaps? I don’t want to send it back again ideally.

Leave it to soak in a bowl of tap water for an hour or so, give it a shake under water, see how it is.

Will try. What's your thinking?
