Good things must not be always complicated:
Lock at this small steampunk gadget for your pocket. It was doe in two hours (after getting the idea;-))
Step 1: How to Do:
I just took an old iron case which was in former times a handlamp. But as you can see the lens, reflector and the bulb are missing. So I just put a piece of "Vulkanfiber" (as you already know by looking at my other projects;-)) a special sort of paper..., four brass screws 12 brass made "Lüsterklemmen "(sort of electric stuff to connect ellectrical wires by fixing with srews), a black covered steal wire a wrist watch an old Lens from another old torch, a rubber fitting, a pice of black rope and some small stailess steel wire.
I just had to cut a new hole in the tin and in the pice of Vulkanfiber for the clock and the lens. The lens was fixed with PU-glue and surrounded with the small rope.The rope was formed to a closed ring an melted carefully together with a lighter. Arround the new brown plate I decorated the "Lüsterklemmen" with the black wire through them. They have also been fixed with PU-glue.
The next step is placing the watch at the right position on the rubberfitting. At least fix the watch across with two small stainless steel wires around the screws....
... and that`s it!!
For changing batteries you just have to srew up the holders and take the watch out.
