Description:
Pulsar 18kt Gold "Time Computer" Wristwatch with Box and Papers, Hamilton Watch Co., no. P75424, synthetic ruby time screen with digital read-out, command button below, 18kt gold signed jubilee bracelet, with its original inner aluminum-clad blue-lined velvet box, outer box, instructional booklet, and power cell certificate, dia. 38 mm, 143g.
Note: The quartz crystal vibrates at 32,768 times per second. This rapid oscillation rate is divided again and again down to more usable precise increments, by a binary divider. The reduced vibrations are fed continuously into the logic area of the computer. When you depress the command button, power is fed from the power cells to the driver, which extracts the time information from the logic part of the computer and releases it to the light-emitting diodes, or digital time displays.
Estimate $8,000-12,000
