VINTAGE STOPWATCHES
I'm interested in 1970's-era digital stopwatches. If you happen to have one of these old timers that you'd like to find a home for, even if it's not working, please send me an e-mail.

Some manufacturer names include Cronus and Heuer.

The image to the right is from the November 1973 issue of Popular Science where the IC supplier Intersil introduced the "Cronus 1" stopwatch and clock. (Click on it to see a larger version.)

ACCUSPLIT II ELECTRONIC DIGITAL STOPWATCH
This is a very early (1973) digital stopwatch that uses a Panaplex-type gas discharge display. It requires four 'C' cell batteries.

Harper Time & Electronics
Mountain View, California

This particular unit has a broken battery tab. Any idea where I can find replacements?

TOTALTIMER SINGLE-EVENT LED STOPWATCH
This is a retro stopwatch with a red LED display. It's powered by three AA-size batteries.

As the front indicates, this is a single-event timer. The start button on top starts and stops the timing. A third press of the button resets the timer to zero.

Each of the seven LED digits has it's own tiny round magnifier lens, similar to early electronic calculators.

The timer was manufactured by

Cronus Precision Products, Inc.
2895 Northwestern Parkway
Santa Clara, CA 95051

CPPI appears to have later moved to Pleasanton, California.

HEATHKIT GB-1201
Heathkit made a handheld digital stopwatch in the late 1970's.

This is the ad copy from their 1977 catalog.

I have a Curtis Matheson Scientific Electronic Digital Stopwatch, catalog number 392-936.
