Since I have got prior experience with watches my test was a little different. The others were asked to file a block of brass into as perfect a cube as was possible. I, on the other hand, was asked to service an ETA 2892. This is an automatic movement with (quick-set) date complication. I had never worked on this movement before. It has some unusual features e.g. the winding gears & the offset train. So, I took quite a bit of time to do this task. I am happy to say that the movement was working after I was done with it :-)
The next task was to cut a piece of brass in a 'V' shape.
like this....
And then it had to be filed so that it matched perfectly, one way......
...or the other.
Looks easy but it takes a lot of careful filing to get the two pieces to match perfectly. If the job is well done, one should not be able to see any light gaps between the two pieces.For the last task, we were given a couple of hairsprings & tweezers.
We were asked to form numbers from 0 to 9 with the hairsprings. This was probably the most delicate task. Hairsprings have a mind of their own & there is a knack to getting the shapes one wants. Here is what I managed. In my defence I will say that my handwriting is terrible as well :-)
Apart from these three tasks, we had to fill out a questionnaire with some maths problems and questions on gears & levers. So that is what the two day test was like.
