In the past few months, we have covered plenty of smartwatches. This Enigma Machine Wrist Watch is not a smartwatch, but it does look special. It has a steel case and scrap leather strap. It is made using an Arduino, a tiny OLED screen, and a LiPo battery. The developer came up with the code for the Enigma himself.
The watch has a 3-button interface. It certainly looks like a conversation starter. In the above video, the developer explains how to set up this watch.
