Pocket Watch Photoshop

How can I improve this photo using Adobe Photoshop?

The photo is of a pocket watch made with a scanner flat. Other pieces that I can put two pieces of a broken pocket watch, one being the clock face and the other being the other.

at the first image analysis and object, greater use dpi / dpi resolution, 600 +, then you can try the sharpening filter, sharpening and more, if, to use the Web may need to make a smaller copy of the jpg to download ..
