Understanding a mechanical drawing
The 0.7 is the distance from the center of the smaller (contact) pads to the edge of the larger (mechanical) pad. 



The 1.2 is the width of the larger pad. 



Notice the dot both arrows point to.

edit
You'll often see the indication BSC next to one of the measurements. This means Basic Spacing between Centers and is a nominal value. Could have been given here next to the 1mm (pitch) value, or next to a 6mm value between centers of first and last pad.
