The Apple Watch Series 1 models were similar to the original Apple Watch, but used a more powerful dual core processor. Like its successor, this Watch was controlled with a Digital Crown and a Force Touch display, and it needed to be paired with an iPhone 5 (or newer).
This Apple Watch Series 1 model is a 42 mm version (a 38 mm version was also available) and used a 312×390 display. The battery was reported to last up to 18 hours, but specific functions were reported to use more battery power than others (e.g., 3 hours of talk time, 6.5 hours of audio playback, 8 hours of working out).
The Apple Watch Series 1 was originally sold in four configurations:
silver aluminum case with white Sport Band
gold aluminum case with cocoa (dark brown) Sport Band
rose gold aluminum case with midnight blue Sport Band
space gray aluminum case with black Sport Band
The Sport Bands were made of fluoroelastomer rubber.
This Apple Watch Series 1 was purchased with a silver aluminum case with white Sport Band. The band pictured is a black Sport Band.
The Apple Watch Series 4 was the first major redesign of the Apple Watch family and added several important functions, including health-related features. The display was over 30% larger and filled the entire screen with curved corners, it added more advanced input capabilities, more powerful processing, and more advanced sensors. This model also included GPS and cellular service for use in the United States and Canada.
Like all cellular-capable Apple Watch Series 4 models, this watch could connect to the Internet without an iPhone and send and receive phone calls with an activated cellular service. It was controlled with a Digital Crown with haptic feedback and Force Touch.
This Apple Watch Series 4 model is 44 mm (previous Apple Watch models were 38 mm and 42 mm) with a 368×448 OLED screen. This stainless steel case model used a sapphire crystal to cover the display. All Series 4 models used a ceramic and sapphire crystal back to connect to the wireless charger.
The Apple Watch Series 4 shipped with “revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app.” When announced on September 12, 2018, the ECG feature was not available until it was released on December 6, 2018, through an iOS update.
The ECG feature on Apple Watch Series 4 marked “the first direct-to-consumer product that enables customers to take an electrocardiogram right from their wrist, capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians. The irregular rhythm notification feature on Apple Watch can now also occasionally check heart rhythms in the background and send a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.”
In addition, a new accelerometer and gyroscope could detect falls and automatically call 911.
