What battery is needed for an Aquastar 4095 Solar powered watch ?

I am thinking you need a new battery. It appears to be a battery operated watch that runs on solar power IF there is light.

How long will a Timex Solar watch last?
The solar movement functionality creates an environmentally-friendly and maintenance free timepiece that can be charged through indoor fluorescent light or outdoor sunlight. Once fully charged, the battery life can reach two months. If worn daily, there is very little chance the watch will stop.

Do you see a itibiti tiny solar panel in the face of the watch? If not like all watches it uses a tiny button battery

Although your watch is solar-power all Eco-Drive watches contain a rechargeable battery known as a capacitor. They last longer than a regular battery but are difficult to get replaced because nobody carries them. Firstly I assure you whoever opened the watch did damage it. The solar sell is under the dial so removing the back would not have exposed it to anything. Rechargeable batteries do not hold a charge forever and do need to be replaced every 5-10 years. In order to know which capacitor you need you need to find out what movement model is in the watch (this is different than the model number of the watch you must physically look at the movement) (unlike batteries capacitors all have the same number on the cell so you need to know the movement number to order the proper size). Once you have obtained the capacitor repairing your watch because no more difficult then changing a battery. I'd ask those people to take the back off again so you can find out what movement is in the watch. Typically it's a 4 digit number but sometimes it also has letters in front of it and I've also seen them with only 3 digits. If you could supply me with the movement number I can supply you with a the proper capacitor at a price of $45 with free shipping and tracking.

needs a battery, telling you im low on power. .solar clean glass and give it lamp 2 days, still not good on solar replace capacitor. repace with cation, needs to be rest . press ac and top of battery, tweezers. greese the gasket of will leak

Take the watch to the jewelers, if the rechargeable battery has failed or solar power issue, it needs to be checked out by a professional.

CHARGE means you have to charge the watch. It depends on what type of movement you have. If it's solar powered, you need to leave your watch under the light to charge it. If it is battery powered - you haqve to buy the new battery and fit it. Rate me,plz.

This watch is battery powered. There is no mention of solar power in the technical specification.
