Chelsea Skeleton Clock

Below is a Chelsea U.S. Army Messenger Center Clock movement circa 1976. The bakelite case that was its home for over 50 years was beyond repair and the dial needed refinishing. So the question was what to do with the movement? I could have looked for another case or I could have used it for parts. Instead a few years ago I decided to increase my clock repair and machine skills. I started cutting away the unnecessary brass on the four plates of a Chelsea 12EI movement.

I worked on this Chelsea movement on and off little by little over the last few years. My surprise was a very eye pleasing shape which emerged once all the excess brass was removed.

This project is still a work in progress as far as its finish is concerned. I used a floor wax as a protectant because it affords a decent protection and is much easier to remove than lacquer. The movement has a real strong tic toc sound to it. This timepiece is an excellent timekeeper. I could use your input weather the Dial should it be totally clear or maybe solid around the Chapter Ring. Finally, it will be displayed under a dome. Any ideas, comments, or suggestions are more than welcome.
