Other than working on watches, I have been concerning myself with poising a balance, fixing the mainspring on a Swiss lever model and trying to get the information necessary to service our dry pressure tester.
Differences are apparent between year 1 and 2. In year 2 there is going to be a lot more theory work. This is due to the increased demands of the written exams on both the SAWTA and CW21 tests. We have been focusing on the theory of the escapement and its adjustment in relation to isochronism.
There are also much more high-tech diagnostic equipment available to the second year students. Pictures follow.
