The PineTime is an open source smartwatch designed for users who want a wearable they can actually understand, customize, and control. Developed as a community-driven project by PINE64, it is built to run custom open operating systems and companion software instead of locking users into a closed platform. Its low-power hardware, compact design, and broad device compatibility make it a practical wearable for developers, makers, Linux users, and open-source enthusiasts.According to the official Pine64 device page, PineTime combines a 1.3-inch 240?240 IPS capacitive touch display with a Nordic nRF52832 low-power SoC, Bluetooth 5 / BLE, a heart-rate monitor, step-counting support, and an 180mAh battery rated for all-week use. It ships in a compact body with IP67 dust and water resistance, wrist vibration, lift-to-wake support, and over-the-air update capability. The official page also highlights its compatibility with Linux computers and phones, Windows machines, and Android devices through community firmware such as InfiniTime.Features Open source smartwatch platform: Designed to run community-built open operating systems and firmware. 1.3-inch IPS touch display: Square capacitive touch screen that remains legible in direct sunlight.
