Hi!
I took a detour from my LEDs, Jump hours and LCDs and took a punt on an unsigned (possibly Catena) Spaceman watch. It works fine, but is very stiff, when setting the time. Has anyone popped the glass off and taken a look inside? Is the crystal held down by a screw thread, because it has no notches or slots.
