Fridays are an odds and ends sort of day in watch school.  We only have class until noon and the morning hours are spent working on whatever you want.  We either play catchup with our watch overhauls or work on projects.

I have been working on an Atmos clock.  The technology of this clock allows it to be wound just by changed in temperature and barometric pressure.  Properly serviced one of these clocks can run for 30 years uninterrupted.  Last week I had installed the fine filament spring (seen below) into the regulator mechanism.  Today I ran everything through a couple cycles in the ultrasonic.  The main clock framework needs to be soaked in acetone to dissolve traces of the original laquer finish.  Once this is complete I can reassemble the clock.

Finally we've been working on gear train calculations in class.  Most of these are just basic algebra, but I hate hand-writing anything so I have begun to program these equations into my calculator which will save me a lot of time down the road.

Numbers and letters, together?!
