Garmin Fenix 3 HR, Gray [Gray, Standard Packaging, Base Model], $299.99
Amazon is featuring the Garmin Fenix 3 HR, gray version, for $299.99. This matches the Best Buy Black Friday deal, which appears to be live now as well. The HR model is sapphire. For what it's worth, I have good experiences with wrist-based HR, but individual mileage may vary.
