The Ollee Watch team has shared a roadmap for the rest of 2026, with a Q2 firmware update due this week and three major features — notifications, activity tracking, and third-party apps via a new platform called Ollee Forge — planned for the year.

A replacement PCB and firmware fork turns a stock Casio G-Shock DW-5600 into a fully programmable, open-hardware watch.

A drop-in mainboard replacement gives the classic Casio F-91W and A158W Bluetooth syncing, step counting, heart rate, and built-in games while keeping the original case, LCD, and feel.

A limited 200-piece kit swaps the Casioak's resin case for full stainless steel with a sapphire crystal and ceramic bezel insert, without touching the watch's electronics.
