Cannot set I have gone to many many different watch places/jeweler to have the battery replaced. Finally my town's most expensive jeweler was able to replace the battery; however, after that, none of the four buttons seems to work. I cannot change the time, I cannot see the backlight, or anything. I really like this watch and do not want to give it up. What hsould I do?

Not sure if you want to attempt this yourself, and advice above to go to a jeweler is excellent, and I marked it Helpful.

Here are three videos on changing a watch battery in a different model:

when you have an expensive watch, take it to a jeweler or, to a pawn shop. Many pawn shops change batteries, and are cheaper than jewelers. Always ask for price first.

to change the battery in a champion watch:
(1) remove the back, (2) carefully peel loose the foam strip and set it aside (3) release the battery retaining bracket with a needle or awl and tweezers, (4) grasp the case with your thumb and forefinger so that your thumb is holding the works inside the case, (5) turn the watch over and the battery should fall out (6) put the new battery in the holder, (7) snap the retaining bracket back in place (8) replace the foam strip (9) replace the back

Have you ried taking it back to the supplier? If it is still under warranty, then they should be willing to replace tha battery and if that is not possible they should replace it.

When I replaced the battery in my wifes' Movado, I discovered that replacing the back is dang near impossible by hand. I guess that is why jewelers in my area charge about $20 to do it, plus battery cost. Jewelers use a special tool called a watch press. I improvised with an Irwin clamp out of my workshop. Note that this clamp has rubber padded jaws, which help protect the watch. I centered the back carefully, and tightened the clamp slowly, and after a bit she popped right in. If you are not comfortable doing this, just pay a jeweler to do the job, because you can ruin an expensive watch if you are not very careful.

1. Place the watch in case holder. Place the watch in the case holder, if you have one. If you do not, place it on a soft cloth.
2. Check for room to work. Check to see if there is room to attach the adjustable case wrench and rotate it 360 degrees. If not remove watch band.
3. Remove case back. Fit the adjustable case wrench into the slots on the case back. Tighten it down until it is snug. Be careful not to slip with this tool as it can scratch the case back of your watch. Work slowly. When it is unscrewed gently pry up the case back taking great care not to damage the internal gasket. If the gasket gets damaged it will need to be replaced with the battery to retain water resistance.
4. Remove battery. The battery will be held in place by some type of retention device. It will need to be removed. Some clips will be removed by using tweezers. Some clips may be moved using a screw driver, and some simply bend out of the way slightly. Remember how it was removed as it must be put back in place exactly for the circuit to be completed after battery change. If the clip is removed, place it and any screws in a paper cup to prevent loss. Remember how the battery was seated, plus (positive) side up or down etc. it needs to be replaced correctly to work.
5. Test battery. Using the battery tester check the battery. If it is dead move to next step, if it is not take the watch to a jewelers for inspection.
6. Clean and inspect battery box. Inspect the battery box the battery came out of. If there is corrosion take it to jewelers for inspection. If there is light dust it may be cleaned with a clean soft cloth.
7. Buy battery. Use the numbers on the battery and buy a new one. Occasionally the number will be obsolete and you will be referenced to a replacement battery in the battery charts. This is the time to also replace the gasket if you need to. Check with a watch maker or jeweler, or the watch company to buy a replacement. We cannot stress enough how important this gasket is to a water resistant watch, without its integrity your fine watch may no longer be resistant.
8. Replace battery. Using the plastic tweezers if you have them, or fingers wearing cotton gloves, replace the battery. Never use bare fingers as finger oils may corrode or short out the new battery. Carefully replace the retention device as it was remove.
9. Replace case back. Make sure that the gasket is in place, and not pinched or caught in the case back when you set it in place. Screw down the case back using your fingers until it is tight and needs the case wrench. Attach case wrench as before and tighten down the case back.
10. Reset and clean watch. Using the appropriate method reset the watch. Use the polishing cloth to clean off any dirt and finger prints.

OR...take to your local jeweler/watchmaker who has the appropiate tools and let them do it for you!!!! :)

Of course, there is the way to change the battery, but for this you have to visit your closest watch repair shop. I do mean WATCH REPAIRS, not the jewellers. Decent watchmaker will definitely open your watch and will replace the battery. Your watch's case appears to be a monoblock. That means you'll need to lift the crystal first, pull the stem second and just then you'll be able to extract watch's movement for replacing battery. Do not forget: jewellers and watchmakers are under one roof, but their trades are completely different. No jeweller can do watchmakers job and vice versa. Rate me, plz.

Ebel are an expensive watch so yes please take it to a reputable jeweller who will remove the back of the watch with a special tool without scratching it and replace the battery, usually without charge and only charging for the battery

There is nothing wrong with your watch. The problem is in tools the jewellers are using for opening the watch.
Despite being under one roof, watchmaking and jewellery are completely different trades and are miles apart. Jewellers usually are equipped with very basic watch repair tools and the case openers are no exeption.
You have to find your nearest watch repair shop and ask for watchmaker, not jeweller. Any decent watchmaker will have the right tool to open your watch and replace the battery in a matter of minutes.
Do not forget to rate, please.

Pretty much any place that changes watch batteries can help. I usually get mine replaced at the department store, but there are places out there that specialize in this and are probably less expensive.
