I dont know anything about this specific watch, but can answer a couple of your questions.
It's a chronograph, the main second hand will move when you start the stopwatch, which is done by pressing one of the two buttons next to the crown. One will be start/stop and the other reset. The subdial on the left is the minute totalizer, it will record how many times the main second hand made a complete revolution, so you can time things longer than 1 minute.
