Heuer Biel Microsplit 200 Solar Vintage the world's first digital stopwatch

Super rare, orig. Heuer Microsplit 200 Solar, presumably the world's first solar-powered digital stopwatch

Blue plastic housing, 10cm x 4cm, ultralight, Heuer signed with original carrying strap

The highlight is presumably the first solar drive / the first small solar cell in watch history, as known from the pocket calculators of the late 70s

Watch, solar drive, and stopwatch pushers in the very best, functional condition

Condition: 1 - 2: very best collector's condition! Barely noticeable signs of age or wear
