Pre-Owned Apple Watch Series 4 (Aluminum, GPS, 44 mm) Apple S4 Processor - Rose Gold

APPLE WATCH SERIES 4 – 44mm The Apple Watch Series 4 (released September 2018) marked a significant redesign with larger displays, thinner bezels, rounded corners, and new health features like ECG and fall detection. The 44mm model is the larger variant, offering more screen real estate compared to the 40mm version—ideal for better readability and more complications on watch faces. Sensors & Health: 2nd-gen optical heart sensor, electrical heart sensor (ECG), improved accelerometer/gyroscope (fall detection), ambient light sensor Audio: Louder speaker (50% louder than Series 3), relocated microphone Battery: Up to 18 hours (mixed use); slightly larger capacity in 44mm due to case size Water Resistance: 50 meters (swim-proof) Other Features: Digital Crown with haptic feedback, watchOS (originally 5, upgradable to later versions; support ended around watchOS 10) Compatibility: iPhone 6 or later (cellular requires iOS 12+) The Series 4 was a breakthrough for health monitoring with FDA-cleared ECG and proactive fall detection. Bands from previous 42mm models are compatible with the 44mm. Condition: These devices are 100% fully functional. They have been fully tested and inspected by our certified technicians.
