Trintec is a Canadian company that's been making aircraft-instrument-inspired watches and clocks for a few decades, and their 30th anniversary altimeter desk clock is an excellent gift for any pilot, aerospace engineer, or aviation enthusiast in need of a suitable way to stay on time.

It has the authentic look of a three-pointer altimeter and has an alarm feature that can wake you from a deep sleep without startling you out of bed. Place this clock on your desk and it'll immediately feel like an airplane cockpit.

Get the 3.5" desk clock for $30 on Amazon. They also have a 6" wall clock for 35 and a 10" wall clock for $45.
