Yeah, I know folk wear them, with no problem ever, so long as they don't store them in the dark for extended periods, but much depends upon lifestyle, including environmental lighting, household lighting, watch wearing habits, whatever.
Cruising the net shows I am not the only one frustrated by lack of hard info, even though a minority, most of us minority want to know and understand machines we own, and treat them properly for max service life.
Citizen provides info for only essentially three lighting/charging scenarios, direct sun at max lux as well as overcast max lux (which is obtained only by pointing directly at sun), and then fluorescent lighting near and far, and then incandescent bulbs (and who uses/has those now?), with zero info on now common LED lighting.
Those of us with experience with assorted batteries used in machines know that for most varieties, including lithium-ion, running until completely depleted is bad for them, and with lithium-ion, most folk know today, thanks to cell phone use, that leaving one at 100% charge is also bad, and in general a battery lasts best when taken to full charge and exercised across a wide spectrum of charge levels through use and recharging, without running them down until dead.
The problem with a new Citizen is that on most of them there is no way to know how long it has been in the dark box, nor charge level, while their advice is to immediately and fully charge (with no way to know when fully charged) in direct sun for what amounts to nearly two days, while severely increasing that time if charged through a window due to THEIR windows filtering/coatings, such as four times the time for charging on an overcast day, which is a loooong time by its lonesome....
My household interior lighting is notable by its lack, I use a stove hood light when cooking, a laundry alcove light when washing clothes, a bathroom which stays fully lit 24/7, and a bedside lamp in bedroom....I stay outside almost entire day near year round, but generally out of direct sun...my only interior charging possible worth a tinker's damn is to hang a watch in bathroom near lavatory light bar which has four LED bulbs of unknown charging ability.....leaving any other lights running or buying a special "solar" charging gizmo just for the watch defeats the entire purpose of the watch in extra expense and power use.
AND I like to put on a watch and leave it on except for showers.
Am sure the watch will work fine with my habits, no doubt about that, even with winter incoming and watch hidden under sleeve for months....but it WOULD be nice to get it up to a full charge now, and KNOW it at full charge, without resorting to leaving it outside for a couple of days where a crow, raccoon, or packrat might take a liking to it enough to add to their own collection.

and luckily, I've never had an issue with either with time loss or a dead battery. 
I think I only have one for dressing up. Ya know, whenever someone kicks or gets hitched, but yeah other than a light windbreaker or my Levi's jean jacket on super cold days, I just don't wear em. I reckon I'm part polar bear.
