MJSCPHBJK Mens Digital Sports Watch, Waterproof LED Screen Large Face Military Watches and Heavy Duty Electronic Simple Army Watch with Alarm

Q: Can you change the battery when it needs one and what type of battery is it?

It does say 'BATTERY CODE CR2025' on the wrist side.

Q: Is the same watch as CakCity is selling?

Yes, it is the same. I bought one from MJSCPHBJK for the slightly better price. I liked it so much, I bought another from CakCity because they had a different color I wanted. Both watches are the same.

Q: Anyone have a link to online directions for this watch? Son accidentally threw them away.

To change from Military time to standard time, simply keep moving through the hours--- the first 24 hours you move through are in Military time, but keep going past that and it will automatically turn to standard (AM & PM) time vs. 00:00 to 24:00).
