Mechanical alarm clock

My first wind-up clock which i got for my birthday. An HES alarm clock with hours, minutes, an alarm that sounds like a fire-alarm and luminescent markings.

Without the dial.the axle in the center drives the hours and minutes(no seconds) and the one above is to set the alarm.

The back.On the left is the iron alarm hammer which strikes the inner wall of the clock.The knob next to is it wind up the alarm and the knob on the right winds up the mainspring.

The balance wheel.

The mechanism to trigger the alarm.The gear is driven by the hours.The small rod that's perpendicular to the axle rises as the gear turns, because of the slope, stopping the alarm from ringing.When the gear turns till the set time,the rod along with the axle drops, releasing the alarm hammer.
