As it is an automatic watch, unscrew the crown at 4H all the way, turn crown clockwise to change the time. Once it is back into position (just before screwing back in), give it a charge by turning the crown 10 times, then screw the crown back on gently and don't force. Also give the watch a horizontal shake to charge.
The crown at 2H works the same way with the screw. Unscrew the crown, place the arrow in front of the minute hand to start recording the time and screw the crown back on (without forcing).
There are 2 buttons on either side, you press them simultaneously, once you press them the buckle folds apart. Then open the clasp with your finger nails and feed through the other side of the strap through the clasp. Make sure the clasp is open completely while you do this so it feeds through easily. Once you find the right spot push through the pin and click into place. Fold the pieces back on top of each other, make sure you fold one side first before the other half. To take off the watch, just click the same buttons on either side of the clasp and it will open up on itself.
