The Withings Steel HR Hybrid Smartwatch is a versatile and stylish timepiece that also functions as an activity tracker. With a silver stainless steel case and band, it offers a sleek and modern design. This model boasts features such as fitness tracking, sleep monitoring, waterproof capabilities, and more - with a once a month charging strength (thanks Nokia!). With a case size of 36 mm, it is compatible with iOS and Android operating systems, making it a convenient and practical accessory for tracking various aspects of your health and wellness. This watch is in good quality used condition and has the upgraded watch band. I’ll throw in the screen protectors, which add an extra layer of protection to an already really sturdy watch! The box is original but the inside styrofoam has been replaced for safer packaging.
