Garmin Forerunner 265 vs Garmin Vivoactive 5
The Verdict
Both watches share Garmin's reliable OS, AMOLED displays, and comprehensive health tracking with SpO2 and heart rate monitoring. The Forerunner 265 offers a larger 46mm display with 416x416 resolution versus the Vivoactive 5's 42mm/390x390 screen, making it better for readability during workouts. Battery life is nearly identical: the Forerunner delivers 13 days smartwatch mode with 20 hours GPS, while the Vivoactive achieves 11 days and 21 hours GPS respectively. The Vivoactive 5 weighs just 36g compared to the Forerunner's 47g, providing noticeably better comfort for all-day wear. Both feature NFC for contactless payments and 5ATM water resistance. The $150 price gap represents the primary differentiator. Choose the Forerunner 265 if you prioritize a larger display and slightly longer smartwatch battery life for fitness tracking. The Vivoactive 5 makes more sense if you value lighter weight and want serious functionality at a lower price point. For most users, the Vivoactive 5 delivers exceptional value without meaningful compromises in core features.
