We've started working on chronographs in class. These are the most complex watches we are going to touch during our watchmaking educations at NSCC. The movement being used to introduce the class to the chronograph is the well built and extremely elegantly designed Lemania 861. The other primary movement which we will be working on, and which is the focus of the SAWTA 4 test is the eta 7750 which we start in a couple weeks.
The chronograph mechanisms add a layer of complexity on what is basically a standard watch movement. All of the normal adjustments (hairspring, endshakes, pallet adjustments) are all identical. What I'm working on figuring out now are the oiling and servicing of the chronograph components.
I will be working on these watches for the remaining 7 or so months of my education at the watch technology institute. The goal is to achieve a total feel and comfort for working with these common mechanisms. I will try and post a detailed overview of a complete chronograph servicing in the near future.

| The pallet fork endshake had to be adjusted on my watch. This is the same operation as on any other manual or automatic watch. |
