I need to replace a battery in a Michele watch. Sometimes I am asked if I want the seal replaced which is expensive. DOn't i need that

FIXYA volunteers usually recommend using a jeweler in a local shopping mall who have the correct size tools and batteries for expensive diamond watches.

I replace the battery in my Michele watches myself. All you need is a very small screwdriver. 3 pack of replacement batteries on Amazon for $5.00. Takes Energizer or Renata 321 battery

I am pretty 100 percent sure that Michele CSX 36 diamonds only comes with a swiss quartz movement not an automatic movement.
So the problem seems to be that the battery is dying and need to be replaced. Stopping and going is usually a sign of a battery dying in a swiss quartz movement.
So it should be nothing major and just a battery.

push the button at 2 o'clock.

You don't say if your "CSX" is a battery powered watch or a mechanical or windup type watch. The solution for a mechanical watch is take it to a watchmaker. If it is a battery powered watch you may be able to do it yourself. Not all work the same way so without knowing what a "CSX" is I will give you one way to try. Pull the crown out two clicksHold the lower button in until a hand moves.You have now selected that hand to adjustUsing the upper button now, press and adjust the hand until it lines up with 12Now hold the lower button againAnother hand should moveUse the upper button to adjust this hand to the 12 positioncontinue this until all the hands line up with 12Press the crown in and press the upper button,the chronograph hands should startPress the upper button again and they should startPress the lower button and they should all go to the 12 o'clock position

I also chipped the enamel on the crown. You should take it to the place you purchased it and they will send it to Michele (actually Fossil) for repair. I had my Michele for 5 years before sending it in to have the crown repaired and have since lost the stem. Prior to that first repair, I did not have any issues with my watch. I really think that the parts used on my watch for the first repair were shotty. Very disappointing, but what do you do?

Replacing batteries is best left to the professionals. Most watches are sealed against moisture and an incorrectly fitted back may result in moisture getting in.

It is always best to go to a watch shop that sells the make of watch you have, since special tools may be required. If your watch is expensive, then you are taking a risk that you may do something wrong.

that happened to me too...the watch repair man told me that I had the stop watch on. The stop watch should serve as a stop watch, not the second hand. The second time on your watch is the small dial at the bottom middle of the face. Once I turned off the stop watch feature, my battery life is fine...I have not had to change my battery in over 2 years now. HOpe this helps.

It's too expensive to change it on proper service or mall... you can purchase battery for amazon and change it at home, take a look here: Rayovac Batteries Lasts as Long Costs Less. I hope this helped. Cheers
