My galaxy gear wont charge

When was the last time you left the watch out to charge? EcoDrive watches are basically daylight powered. It can also use light bulb light to charge as well. My first suggestion would be to place it face up somewhere where it will get plenty of sunshine and leave it to recharge. It might take 3 or 4 days if it has gone totally flat but it will cost you nothing to do this. If this doesn't work I would recommend taking it to a good Citizen dealer and see if the watch can be serviced. If you have pulled the crown too hard you could have damaged inside the watch.
A built in feature on some Citizen watches is the '2 second tick'. If the charge is low the second hand will jump 2 seconds at a time instead of one. When recharged it goes back to normal.

There is normally a calibration position. Try pulling out the center crown and pay with the upper and lower pushers. Do that with the two positions. You can watch this video https://www.youtube.com/watch?v=uVQFjeLYfpI

try pressing the power button for 3 to 5 secs. If still no power, connect it to a working usb/power source and try to turn on again.
If no sign of power even connected, you might need a battery replacement. A little history on what happened before this will be helpful

According to Samsung's site, the battery on the galaxy gear smart watch should last up to 25 hrs.

Yeah, the samsung galaxy gear smartwatch has a camera. It's 1.9 MP.

From your description the solar cell charges the battery and keeps it topped up. I think the rechargeable battery is the problem because when the screen goes blank the battery level drops to low and the LCD blanks out which would explain the intermittent operation of the watch. I think it is worth getting it checked out with an estimate.

There are only two things that can cause screw down crown to malfunction. First is dirt and second is weakened/damaged thread. In first case you need to use ultrasonic cleaner by immersing the crown AND case to get rid of any dirt and grime sticking on both threads. If the matter is weakened/damaged thread - you will have to fit new crown and (possibly) new case tube on which crown is screwed onto. This can be done by decent watchmaker only.
Rate me, plz.

I thing required cleaning for the movement and new capacitor.

i have this problem too... it's for my gucci 5500M. i haven't tried replacing the battery, but i remember the second hand getting this problem when i had to change the time. i wonder if a small gear broke inside the watch, but the weird thing is that the time still stays on time.
