Apple Watch Series 4

Specifications

• Build and Material: Apple Watch Ultra 4 uses a Grade 5 aerospace-grade titanium case, giving it a combination of strength, durability and relatively low weight. It is available in Natural Titanium and Black Titanium finishes. The front is protected by a flat sapphire crystal, which provides strong resistance to scratches and everyday wear. The watch is also MIL-STD-810H tested for use in demanding environmental conditions. Apple
• Size and Dimensions: The Ultra 4 has a 49mm case, measuring approximately 49mm high, 44mm wide and 12mm thick. Its large body accommodates the larger display, bigger battery and additional outdoor sensors. The watch weighs approximately 63.0g in Natural Titanium and 63.1g in Black Titanium, excluding the strap. It is designed for wrists measuring approximately 130mm to 210mm.
• Display: The watch features an Always-On Retina OLED display with LTPO3 technology, offering a 1Hz refresh rate when appropriate to conserve power. The active display area measures 422 × 514 pixels, with a pixel density of 326 pixels per inch. The display reaches an impressive 3,000 nits peak brightness, while the minimum brightness can drop to 1 nit. This makes it particularly suitable for outdoor use in bright sunlight.
• Processor and Performance: Ultra 4 is powered by Apple's S11 SiP with a 64-bit dual-core processor and a 4-core Neural Engine. The S11 provides the processing power required for health monitoring, GPS tracking, workout analysis, apps, Siri and the watch's newer intelligent features. It also includes support for Apple's newer AI-powered capabilities.
• Storage: Apple Watch Ultra 4 comes with 64GB of internal storage. This provides space for apps, music, podcasts and other compatible content, allowing users to keep more information on the watch without relying entirely on the connected iPhone.
• GPS: Ultra 4 features precision dual-frequency GPS, supporting GPS, Galileo, QZSS and BeiDou satellite systems. Apple positions it as having its most accurate on-device GPS in a sports watch. The dual-frequency system is designed to improve positioning accuracy, particularly in challenging environments such as urban areas, forests and locations where satellite signals can be obstructed.
• Connectivity: The Ultra 4 includes cellular connectivity, supporting 5G RedCap and LTE networks on compatible carriers. It also incorporates satellite communication capabilities for supported safety and emergency features. This means the watch can provide connectivity and safety functions in situations where a nearby iPhone or traditional cellular connection may not be available, subject to regional and service availability.
• Battery: Battery life is one of the major advantages of the Ultra 4. Apple rates it for up to 50 hours of normal use and up to 84 hours in Low Power Mode. For outdoor workouts, it can provide up to 18 hours in standard outdoor workout mode, 25 hours in Extended Workout mode, and 45 hours in Max Extended Workout mode.
• Charging: The Ultra 4 supports fast charging and can reach approximately 80% charge in around 45 minutes. A 15-minute charge can provide up to 18 hours of normal use, while approximately five minutes of charging can provide up to 10 hours of sleep tracking. This makes it considerably more practical for people who use the watch continuously for fitness and sleep tracking. Apple
• Health Monitoring: The Ultra 4 features Apple's new Health Sensing System, which combines advanced optical and electrical sensors to provide continuous health monitoring. It tracks heart rate, heart-rate variability, respiratory rate, wrist temperature and other health measurements. Apple says the new system provides its most accurate heart-rate sensing in a wearable, with more frequent background heart-rate and HRV measurements. Apple
• Blood Oxygen and Temperature Sensing: Ultra 4 includes a blood oxygen sensor and temperature sensor, along with the other components of its Health Sensing System. Temperature measurements can contribute to health and cycle-tracking features, while blood oxygen information is available through the Blood Oxygen app where supported.
• Diving and Water Resistance: The Ultra 4 is rated WR100, making it suitable for high-speed water sports and recreational scuba diving to depths of 40 metres. It includes a depth gauge and water-temperature sensor, making it considerably more capable for water activities than the standard Apple Watch models.
• Warranty: 24-Month Warranty | 6-Month Screen & Water Damage Insurance | Free Accessories.
