Telechron's last cyclometer clock was the only one made of metal. It's really very nice tho' a little on the small side. Unlike earlier models, the numbers were protected with a plastic cover and you set the time by rotating the wheels from the bottom. The original color was called "gunmetal" but they always end up this brown/bronze hue. If you see one gleaming like a new penny, it wasn't a rare variation--it's just been polished.
