AVI 8 Hawker Hurricane Automatic doesnt work

[boombooz]

recently my automatic stopped working and doesnt wind up anymore even though i always keep it in a watch winder all the time. 

It is too cheap to let a specialist oversee the problem and therefore i want to repair it myself with a little support from you guys i will open it .

 

But first i want to ask what kind of movment does this watch have and what kind of general problem it could have. 

 

i will make images of the repair process in return

Thats a cheap 21j movement which can be purchased new for round $30.
