This clock, based on the pleasing lines of the Lyre, was designed and built by the author for entry in the annual Craft Contest of the National Association of Watch and Clock Collectors (NAWCC) and won a gold in international competition for handmade clocks at the National Convention in Orlando, Florida. The clock is of English pattern, with spring and fusee drive, maintaining power, a one piece hand pierced skeleton dial, and unusual sun and planet pinion motion work. It is wound from the front, has an 8-day run, and stands 16″ above its black walnut base. The pendulum is rear mounted and has a heavy, brass shell bob poured with lead for high Q. A 1/8″ thick plastic cover protects it from dust. The escapement is an original design by the author and is of the spring pallet type. To enhance animation, it has been enlarged and brought forward of the front plate for ease of viewing. Its action is lively, positive, quiet, and endlessly fascinating. The escapement is an unusual spring pallet design by the author.
