Why the Pulsar hid its display
The 1972 Pulsar made telling the time feel like an act of technology. Its red light-emitting diodes—tiny electronic components that glow when current passes through them—were too power-hungry to stay lit continuously. Pressing a button briefly switched on the time display; when it went dark again, the watch conserved its battery.
That interaction made the watch feel unlike a conventional timepiece. Instead of glancing at hands or a constantly visible dial, the wearer summoned the time on demand. The button was not just decoration: it was part of the engineering compromise that made a glowing digital display practical on a wrist.
A luxury object built around new technology
The 18-karat-gold case and $2,100 price placed the Pulsar far beyond an ordinary watch—and, as the comparison with a new Ford Pinto suggests, beyond many household purchases. The price reflected more than the precious metal. A compact electronic watch with a digital display was a novel, technically demanding object, presented as both a timekeeper and a glimpse of what consumer electronics might become.
That combination also exposed a tension that would shape wearable gadgets: advanced features had to fit inside a small case and run on limited battery power. The Pulsar’s solution was simple and memorable. It made the wearer press for the future, then let the red numbers vanish.
