Project description
Freewatch is a fully open electronic watch project featuring an
integrated GPS.*
The project was started at CERN to make a special present for a retiring
colleague who likes hiking and timing.
The full design (electronics, mechanics and software) is available under
open licenses and, what's more, the design is exclusively made with open
tools.
