To set the time on a Dakota one button watch, you will need to follow the instructions in the user manual that came with the watch. If you do not have the user manual, you can try the following steps:

1. Press and hold the button on the top right side of the watch: Press and hold the button until the time display appears.
2. Set the time: Use the button to set the time. The specific sequence for setting the time will depend on the make and model of your watch.
3. Exit the time setting mode: Once the time is set, you will need to exit the time setting mode. The specific steps for exiting the time setting mode will depend on the make and model of your watch.

It is important to note that the steps for setting the time on a Dakota one button watch may vary depending on the specific make and model of the watch. If you are unable to set the time using the steps above, it is recommended to refer to the user manual or contact Dakota customer support for assistance.
If you have a "his and hers" set of Dakota watches, the steps for setting the time on both watches should be the same. You can use the steps above to set the time on both watches.

Found these two answers on this site from 2010.
How do you change battery on Howard wrist watch how does bach come off

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.

This is the model with the exposed button on the right side. The back does not come off, but the front does! If you use a loop you may be able to see a notch between 7 and 9 O'clock. Be very careful because the gasket keeping the watch water resistant is right there. You do not want to harm it. I put the watch in a holder and place a very thin jewelers screw drive on the side. With a jewels hammer I tap lightly until the front comes off. You must then carefully remove the movement from the case and not touch the hands. In order to close the watch after battery replacement, a watch press is a must. Without the press, you won't get the watch closed. The manufacturer suggests taking the watch to a qualified professional. You can send it to the manufacturer as well and they will change the battery for you. The Manufacturer is La Crosse Technology in La Crosse Wisconsin.

you can get the crystal off, but not back on. There is a special tool that is used to compress the crystal to make it fit in the bezel. Besides, if a piece chipped off, it is no longer waterproof. Take it to a jeweler and he can put a new crystal on in no time. Crystals are not expensive.

try turning DST off if possible.
