i followed the instructions on the Citizen website for a system reset and it worked. Unfortunately, the regular way of setting the digital hour does not. Maybe a technical problem? The movement number for the Aqualand duplex is C506.
1. unscrew the analog adjustment crown and pull one click
2. press and hold the other 3 buttons for 3 seconds and release.
3. push the analog crown back and adjust the digital time.
this is a system reset so you will have to set the date. You will lose your settings and your dives. good luck.

The plastic wrist band doesn't have to be cut away. You need to dislodge the spring-loaded end of the pin from the hole in the plastic with the blade of a sharp thin knife.
The you proceed to lift one of the 4 snaps to open the cover. The battery is under a white translucent inside cover.
The original battery was Sony SR621SW.
Pay attention to the rubber seal ring when putting the watch back together.
