Google Pixel Watch 4 45mm (Obsidian) – Android Smartwatch with Gemini AI

The Google Pixel Watch 4 is Google's flagship wrist-worn smartwatch running Wear OS, optimized for Android phones (particularly Pixel devices). It features a 45mm Actua 360 display — 10% larger and 50% brighter than Pixel Watch 3 — with Gorilla Glass. Built-in Gemini AI powers quick replies and contextual assistance. Health tracking includes HR, SpO2, sleep monitoring, and 40+ exercise modes with dual-frequency GPS for accurate route tracking. Battery life reaches 30 hours standard or 48 hours in Battery Saver mode; new side charging delivers 15 hours in 15 minutes. Water-resistant to 5ATM. Best for Android users seeking premium AI integration and a bright, modern display—though battery life trails Garmin and Amazfit competitors.
