CALTA Watch Instructions

There are two small indentations on the right side of the watch.
A = upper     B = lower
Using any pointed instrument:  Press B repeatedly until you see what you want (month, day, hour, minutes).
Press A to set value of each one.  Press B to go to the next setting.
When finished with all settings, press B repeatedly to check all
and make sure " : " is flashing when completed.

Note . . . . The numbered bezel is purely decorative.
The back can be removed and the battery changed.  It came with a Maxell LR41.  There is a tiny indent along the edge of the back where a very small screw driver (2mm) can be inserted to pop off the back . . . after the battery is changed, just press it tightly back into place.  (It does not twist off.)
