60 Second Timer Armband Project: ESP32 + OLED + 18650 + 3D

I need some way to count to 60 while I rest between sets at my new gym. There are *no* clocks on the wall, probably on purpose for some reason.

I developed this very quick-and-dirty project with an ESP32 development board, an OLED display, an 18650 battery, a 3D printed housing and two velcro straps.
