UNA Watch (Modular GPS Running Watch)

UNA Watch (more information here).

This is a modular, tinkerable, user-replaceable GPS watch with open source software. Designed to be modified, messed with, etc. I have no skills in this area, or necessarily interest, but hoping someone else does - it's certainly a cool platform.

No damage or issues whatsoever; used for less than 50 miles total. Will ship with original packaging.

Photos and timestamps here.

Asking $100, OBO.
