Overview
This Garmin GPS watch (model 010-02120-30) weighs about 40 grams and comes in black, built as a lightweight wrist unit for tracking runs and workouts by satellite.
Garmin's watch lineup spans running, multisport and outdoor models, and this listing gives only the part number rather than a named series, so the exact feature set such as battery life or included sensors is not confirmed here. The 0.04 kilogram weight is in line with a compact running watch rather than a bulky multisport case.
