Can someone help me identify the "value" of this movement?

The movement is an ETA, 853. It is marked Swiss and 15 Rubis. I bought the watch in southern Spain years ago. I am curious if this is/was a nice base movement. Also, it "ticks" quite loud. At night, I have to put it into a drawer to keep from having the room enveloped by the sound of the movement. http://img.photobucket.com/albums/v370/MGB-IV/Tanger/TangerMovement.jpg
