Looses time when worn. but keeps time when not on wrist

have clasp adjusted

Is it all digital (with a digital readout), or does it have two, or even three hands that point to the time?

Check the two connections where the battery makes contact, most likely one of the screws is loose or missing, or may have some corrosion from a battery leak..

Dear William,

there must be a problem with energy (not enought) or too thin battery (did you exchange it latelly) - loosing contact when you schock the watch.

Let me know when you check this...

Is your watch covered for most of the time that it is being worn?( by sleeves perhaps?).

There must be a lower limit of exposure time required to keep the battery charged (so that it can run overnight), perhaps this requirement is not being met.

Visit your local Citizen dealer and for new capacitor. It looks like your old capacitor can not accumulate enough power to keep watch going in darkness.
Rate me, please.

Your band may be too loose. This is the model that moves when worn correct?

if there is a black screen and shows chg thats mean your battery level is to low ////// so you must charge as soon a possible,,,,,,

Your watch is a automatic. All automatics need to wind-up before being worn at first , or if not worn all the time. Automatics will work with-out being wound ,but will not keep time. Wind your watch at least 50 turns (using the crown) or shake about 150 times , and then try it . Automatics need that back-up power to insure it's accuracy.
