Russian “MIG” cockpit clocks are widely available online and make a great desk clock. I recently received one for my birthday and designed this 3D printed stand for it (available free on Thingiverse). For reference, here’s a bit more about these clocks.
The Jaeger-LeCoultre Memovox is a true classic: A novel watch that sold well when it first appeared and lasted for decades after, continuing even today. Although not the first alarm wristwatch, the Memovox came on the market in 1951 and became the first ever automatic watch with an alarm function in 1956. Jaeger-LeCoultre upped the ante with a high-beat version in the 1960’s and 1970’s, and has continued offering this useful complication in today’s Master Memovox and related models.
