This is a clock that was made by Cartier in the 1920s. It has a clear Quartz handle on top. The Quartz handle was broken and needed to be duplicated. As you can see it is in the shape of a “D” which is also cylindrical in cross section. Making the outer shape isn’t very difficult but it can be quite time consuming to shape, sand, and then polish the inner area of a piece like this. After it has been cut, a ½” wide slot was cut out of the bottom where it attaches to the body of the clock.
