The Apple Watch is sold in a 38 mm and 42 mm SKUs in black stainless steel, anodized aluminum and 18-karat gold, in addition to sport, leather, and metal watch band options.
It includes a Digital Crown to dial scroll, zoom, and navigate, GPS, Wi-Fi, Bluetooth, heart rate sensor, 11 watch faces, and options to view email, weather, stocks, maps, and send dictated or audio replies.
