This is an Architect Chronograph. To start the chronograph press the top start button. To stop it press it again. To reset it press the reset or bottom button. The sub dials are minutes, hours, and seconds.

The Fossil web site has all of the instructions: https://www.fossil.com/webapp/wcs/stores/servlet/StaticView?langId=-1&storeId=12052&catalogId=10052&page=Instructions&nav=custCareNav

Go to a watchmaker/technician. They will have a press that they can use to apply even pressure putting the crystal back in place. Be careful that you do not lose the teflon seal sitting where the crystal goes and do not let any dirt or contaminants get to the face of the watch. Be sure you ask them to pressure test it to be sure it is water resistant.

The dials are part of a Chronograph (stop watch) I assume there is a second, minute, and maybe a date function. Usually the large second hand is part of the stop watch on only moves when you start the stopwatch (top right button) push again to stop and reset back too zero is the bottom button. Usually to set or zero out those dials pull out the crown to the first click (also sets date) then push the top button to set the seconds (big hand) and the bottom button to set the other. sometimes you may need to pull the crown out to the second click (also sets hour and minutes) to set add'l dials. This is generally how you set most chronograph watches the button you push and what moves may be different.

1. Pull out the time set mode button.
2. Press the upper right button repeatedly until the sweep hand makes it back to 00/60.
3. Press the time set button back into normal position.
