tl;dr It’s a foundation for a wearable platform. It’s a Nato watch strap threaded through a PCB with a coin cell battery holder between the PCB and the strap. I’m using a Attiny85 this time around but could be used for most chips/dev boards. This is a proof of concept to iron out any problems […]

Elliot Williams writes on Hackaday:
[Max K] has been testing the battery life of his self-designed watch under real-world conditions. Six months later, the nominally 3 V, 160 mAh CR2025 cell is reading 2.85 V, so the end is near, but that’s quite a feat for a home-engineered smart watch

The VFD display (IVL2-7/5) is a piece of soviet new-old-stock (NOS), and has a unique look to it. Making a watch out of it is a logical progression for anyone wants to give portability to the mesmerising glow of the display.
Callum shared the board on OSH Park:
Here’s a video of the display in action:
