Our quick verdict

The Apple Watch Series 12 46mm runs watchOS built around the iPhone, gives daily readiness scores and is swimproof to 50 m and slimmer, though it works only with an iPhone, while the Huawei Watch D3 takes cuff-based blood-pressure readings, lasts much longer between charges (6 days vs 24 hours) and works with Android phones and iPhones, though it is not water-resistant.
