Building an Analog Meter Watch
A new type of analog watch has been created by Sahko, featuring a single needle to display time. The watch utilizes a Raspberry Pi Pico and a digital-to-analog converter to drive an analog coil meter. Its design includes a custom PCB dial backer and a CNC milled aluminum case, showcasing quality craftsmanship.
- ▪The watch displays time using a single needle, which can show hours, minutes/seconds, or the current month or day of the week.
- ▪It is powered by a Raspberry Pi Pico and a digital-to-analog converter.
- ▪The dial backer is made from a custom PCB for durability, and the case is CNC milled from aluminum.

Building An Analog Meter Watch No comments by: Zoe Skyforest May 23, 2026 Title: Copy Short Link: Copy Most conventional analog watches have two or three hands, covering hours, minutes, and seconds (where present). [Sahko] has built a different kind of analog watch that creatively displays the time with just one. The build is based around a simple analog coil meter, which, at its heart, just sweeps its needle across a scale based on the voltage input to the device. A Raspberry Pi Pico is employed to drive the meter through a digital-to-analog converter. Pressing the buttons on the outside of the device tells the watch to display hours, minutes/seconds, or the current month or day of the week.
