Ok I'm going to venture a guess here, I think the dial and movement come out through the front, can that line running around the top be a seam of a threaded screw down bezel?
Try grasping the top above the seam line with your right hand and the bottom with your left hand hand and twisting so that your right hand is turning anti clockwise.
Lets me know how it goes.

Damn, bugger, bum....................not working, I clicked on the white box and got...........nothing
So I right clicked, it said 'movie not loaded' and underneath it said 'about macromedia flash' so I clicked that, it took to me to another site which told me I already have version 8 loaded, so it looks like its not meant to be for me

@mossanti please note this is the second time today that I find myself forced to move one of your posts.
Please note the Panerai section of the photo gallery is not where we talk about watches its where we view them.
