Apple Watch Series 4 (Aluminum, GPS, 40 mm) Specs
Identifiers: Watch Series 4 40 mm - MU642LL/A** - Watch4,1 - A1977* - 3225*
All Apple Watch Models
The Apple Watch Series 4 models look similar to earlier models, but have larger displays, more advanced input capabilities, more powerful internals, and more advanced sensors (most notably a new accelerometer and gyroscope that can detect falls and an electrical heart sensor).
This particular model, the Apple Watch Series 4 (Aluminum, GPS, 40 mm) does not have wireless cellular capability, but higher-end models in the series also are capable of being connected to the Internet without a "tethered" iPhone. This "GPS" model is required to be connected to an iPhone 5s or newer running iOS 12 or later for most functionality.
All Apple Watch Series 4 devices are controlled with a Digital Crown with haptic feedback and a Force Touch capable display. This particular Apple Watch Series 4, the GPS model in the 40 mm size, features a 324x394 LTPO OLED screen with "strengthened, lightweight Ion-X glass" packed in a 7000 series anodized aluminum housing with an "all ceramic and sapphire crystal back" that connects to the charger.
Battery life is an Apple estimated "up to 18 hours" overall, but more specifically "up to 2 hours" of talk time connected to an iPhone, "up to 10 hours" of audio playback from Apple Watch storage, "up to 10 hours" working out indoors and "up to 6 hours" working out outdoors with GPS.
There are six different options for this particular Apple Watch Series 4 model. Options include a silver colored aluminum case with a white fluoroelastomer rubber "Sport Band" (pictured, left) or "Seashell" gray fabric "Sport Loop;" a gold colored aluminum case with a "Pink Sand" fluoroelastomer rubber "Sport Band" or "Pink Sand" fabric "Sport Loop" (pictured, right); or a dark "Space Gray" colored aluminum case and a black fluoroelastomer rubber "Sport Band" or black fabric "Sport Loop."
