In this video, I'll be servicing and then testing the AS1187 and Cupillard 233 movements. This isn't just a timegrapher test. I'll be doing something a little more "unconventional"... perhaps irresponsible. I'm going to strap these watches to the handlebar of a mountain bike, and then send them down a mountain to see what happens.

I hope you all enjoy this little experiment.
