What is this tool? How do I use it?

Got this from a buyout.  Anyone know what this tool is used for?  Shown are both sides and the box it came in.

Looks like some kind of caliper for measurement. Can't make out the word on the box.... cylinderhshenmasse?

Is this even a watch tool?

Cylinderhöhenmasse, it's for measuring the cylinder height in the watch for cylinder escapements. Never seen one before.

Thanks Nicklesilver! From the name, Cylinderhöhenmasse, I figured it had something to do with cylinder escapements.  But I have no idea how to use it.  I looked the name up on the web and nothing useful turned up yet.  I'll you all know when (if) I figure it out.
