- Brand: GREENON - Model Name: A1 III - Features: GPS function, swing check, watch - Color: Black Thank you for viewing. This is the A1 III golf watch, which features a very bright organic EL touch panel LCD. It supports Michibiki, providing very high accuracy. Green undulations can also be displayed. I am selling it because I no longer use it. The continuous usage time is 10 hours when new, but even now, the battery still has plenty of life left after a round. The original box and charging cable are also included.
