PINE64 SmartWatch "PineTime"

The PINE64 SmartWatch, dubbed "PineTime", is a product of a community effort for an open source smartwatch in collaboration with wearable RTOS and Linux app developers & communities.

PineTime development has been broken down into two distinct phases:

• Phase One - PineTime Dev Kit Project on October 2019
• Phase Two - Introducing the PineTime smartwatch around Q1 2020, depending on development results in Phase 1.
