You have to dismantle your watch first.
Check the back of case- if there are visible screws- undo them and take caseback off. You should see the battery. Take it out, read the numbers on battery and replace with the same one.
If you can not find any screws on caseback- you have to undo screws from the dial side, get the movement out and then change the battery.
BE WARNED: if the watch must be opened from dial side, you can easily damage it as some particular skill is needed. Do it on your own risk.

Good luck

I have a Nike WC0021 watch and it beeps every hour. How can I turn it off?

Press and hold the top right button for 3 seconds then release - this should turn off the 'chime' function.

Change battery

if you watch a notch in the middle of the watch back then all you do is slip a large coin and twist off the capsule top by pushing down and turning counter clock wise. If the back of your Nike has a plate with 4 screws in the corner then y ou need a precision screw driver and unscrew all 4 screws on the back to access battery back.

Battery is gone (I think) and regular watch repair places don't fix it (need a special tool to open it)

does it have a slot on the back ? usually Nike watches are made to easily replace the battery usually with a nickle slot on the back or screws on the corners. The batteries they have are usually common 2806 or similar coin sized batteries. It will say on the back of the battery .

Most jewelry or watch repair shops can easily replace these batteries. if you bought the watch within a year , have receipt and something is broken. You can send it back to nike to be repair for free. It is done by parsec located here

How do you change the battery?

Thank you for contacting FIxYa.
I would read the NIKE support site before deciding to do any battery changes on your own. As a retail jeweler/watch service tech I would HIGHLY recommend you doing what they suggest:
