For the stop watch shown in the attached file (picture):
Outer dial is divided into 60 seconds with 1,5 second graduations.
Smaller circle do one hour for each revolution.

I do not unstand your picture. Why the divisions are 100 and 30?
Please explaine it in more detail.
I need more information to create a stop watch you need!
