Scanning electron micrographs of vintage watch. Hand, hour detail. Comparison of two techniques. First image scanned using a 1.5 kilovolt electron beam, and second image was at 0.5 kV. Note that the hour marker "1" has vanished on the second image, and the overall appearance is different. Note also the luminous filler remaining near the tip of the hand, and the large "hole" where filler has fallen out, most apparent in the second image. This is an old watch...
