It was a great day, and really opened my eyes to the challenges inherent in crafting and repairing a watch movement. I knew that watches were little machines, but actually unscrewing things (Very small things!), seeing how they fit together, and trying to put all the parts back in order was illuminating. I have a whole new level of respect for watchmakers now.
Plus, it was so incredibly fun to put on a lab coat, sit at a watchmaker's bench, learn more about the mechanics of watches, and about JLC, the company. I was very impressed with the Master Class, and am appreciative that JLC offered this opportunity.
I'm not sure about my future as a watchmaker though -- one screw completely lost, and another one broken, says to me that I should keep my day job! 
Cheers,
