Nice watch! I think old lubricants are gumming up the gear train. I got a few nice "defect" watches cheap from ebay that only needed some cleaning and some lube. (very tiny gears though, difficult)
Citizen DIGI-ANA 8943 analog is slow
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!

Moebius lubricant for quartz watches, don't remember the exact type, I've got the little bottle already a very long time 
sent from my call and internet thingy

As said, that's a fairly classic sign of lubricants drying. hen you wear it the warmth of your wrist helps to keep them liquid but when they cool down (after you take it off) they turn more like treacle.
It's not a good idea to put new oil in without cleaning first because any particles in there (including any dried oil) will tend to form a grindig paste with the fresh oil and cause wear.
I've never had a chance to strip one of these down but it should be a pretty straightforward movement given its age and very basic functions (as far as the analogue is concerned). But it's probably not one for the complete novice because (a) quartz trains tend to be on the small side and (b) you'll need to remove all the LCD parts in order to do it properly.
eta: Great watch btw!

Ah the Robot Face.
I brought mine a few years back, battery had leaked and melted many of the tracks. I re-soldered it and got some life out of it, but short lived.
I have a new pcb to try in soon...mine will say hi!

I've been looking forward to getting this ready to wear this summer.... I can do a step by step if you are at all interested in a bit if DIY....but as Joe advises, it might not be the best to start on. Perhaps search for a donar watch, you do see them on eBay, at least to know you have a contingency plan.

Thanks to all for your advice and comments. I downloaded the 8943 technical manual. It looks complicated to me. This is my first time to service a watch. If anything goes wrong I can kiss my watch goodbye. I am still confuse the kind of oil or grease to use. There are different kinds on ebay and prices ranging from $10 to $50 for a small bottle.
I will be most grateful and very appreciated if you could do a step by step DIY. Please PM me when your step by step is ready to roll.
Thanks again for all your help!

Hi
The reasons for this fact may be several : not synchronized analog and digital watches. or dysregulated crystal oscillator (you can fix it by using a trimmer).
Both steps are simple - but if you adjust time by using trimmer you need to know how to open the watch, Which trimmer regulate - because there are two - one for the time and the other for the thermometer. And which way to turn the trimmer. Synchronization Analog and Digital Watch - is possible - using only buttons...
