Mmmm… I love me a jump hour. Mitch at Watchismo is holding a sale on most of his vintage stock including a crazy Jaeger LeCoultre Masterquartz LED and a bunch of Jump Hour “digital” watches from before the era of digital.

This crazy Sicura is particularly amazing with its battery lamp lighting up a handwind movement.

Vintage 70′s Swiss Sicura Instalite Jump Hour Mechanical Digital

Mechanically wound by manual movement, lamp function by battery and lit by pressing upper right pusher

Blue Dial lights up in addition to three portholes above display

Only in the 70′s, right? Huh? Am I right?
