Does not hold charge - Seiko Titanium SMY042 Wrist Watch

By far the most common reason for that watch to fail is the Owner believed it was waterproof and got it wet.
It is "splash resistant", which is meaningless.

Hi, As far as the info you quoted ,I am afraid that your battery does not hold charge anymore or charging circuit has a problem and ,it does not charge.
If I were you I will replace the battery first to see if it will work..
If problem continues ,then it will be an expensive repair action as next step..
It is up to you to make it repaired or to buy a new one since repair sometimes costs almost the same price.
Hope this helps! Take care and please Remember to rate/vote for us to continue

The rechargeable battery needs to be replaced in the watch, you need to take it to a jeweler to have a new one installed.

You likely have a dead battery. Follow the instructions on this web site http://forums.watchuseek.com/f43/how-change-ctl1616-rechargeable-battery-41076.html
it is clear and covers most casio models. Watch closely for the springs when taking your watch apart. You can order the battery online (the best option) but most people that use a standard lithium battery seem to have no problem.

mcdevito75 here, Possibly the battery is worn out. An old battery will not hold a charge, Visit a small watch repair shop in yourarea for a new battery.

As you are probably aware, the battery should hold its charge for a considerable time, so the seem to be two alternatives:-
1) the battery needs replacing
2) it has developed a fault.

If the watch is still within the warranty period, then take it back, if not then you could take it to a watch shop and aske them to check the battery. If it is OK then it looks as though it must go back to a repairer.

For this, go to the Casio wed site (casio.com), select "support" and find your nearest service location.

try to let it set in full sunlight for the whole day. if it dosn't come bake on you need the battery replaced. And yes they do have bartteries thats how it hold a charge over night. but these batteries are not cheap, but worth it to keep a skyhawk going

Change the battery. This happened with mine along with the battery needing charging more frequently. In my opinion, Casio's assertions that you won't need to change the battery is pretty much of a joke. My jewler concurred.

After changing the battery I can now press the light switch button and the watch works normally.
