Buying call

Buy the 45mm Pixel Watch 3 at a discount if you have an Android phone and want good fitness tracking: reviewers got up to 48 hours per charge against Google's 24-hour rating, and Readiness and Cardio Load scores no longer need Fitbit Premium. It's IP68, with a brighter, larger screen than the Watch 2 and faster charging. Skip it if you want the newest software, because Google promised three years of updates from its 2024 launch, and the Pixel Watch 5 adds dual-frequency GPS. It doesn't work with iPhones and has no sapphire glass.
