From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

That looks like a great project the battery life must be iconic

They have a page about that: https://watchy.sqfmi.com/docs/battery-life

With only time keeping, Watchy should have a battery life of 5-7 days, while with fetching data over WiFi, it should last between 2-3 days. These numbers can be extended through further optimizations (e.g. sleep during off hours, waking up only on motion/tilt, etc.).

By default it wakes up the CPU and updates the display every 60 seconds, but you could totally change this to make it only update on demand (the most efficient would be by button press) which should extend the battery life waaay beyond 7 days.
