The beloved classic gets an upgrade. The Sensor Watch is an open source board designed to fit inside the Casio F-91W. From Joey Castillo on GitHub:
The Sensor Watch is a board replacement for the classic Casio F-91W wristwatch. It is powered by a Microchip SAM L22 microcontroller with built-in segment LCD controller. You can write your own programs for the watch using the provided watch library, program the watch over USB using the built-in UF2 bootloader, and then install the board in your existing watch case to run your own software on your wrist.
