I have the Citizen DIGI-Ana since the early eighties. I wear it everyday to work and is still working fine until last week. I noticed the analog started getting slow if I am not wearing it on my wrist. The digital is accurate. If I leave it on the desk the analog will lose about 8 minutes after 45 minutes and an hour 30 minutes after 6 hours. The room temperature is 65F/19C.  If I wear on the wrist overnight in bed, the analog runs fine without losing any minutes. I replace with a new battery and is still the same. So I am not sure what’s wrong with my watch. May be our members have some insight on this problem. Thanks!

When was the last time it had a service? I cant remember but does the analogue have jewels that need to be oiled? If you are stuck I think I have one here I can pop the back on.

Nice version by the way, rare with the white face.

Thanks for your reply! It has never been service. I think I shall try to lubricate the gears.
