Apple Watch

Apple Watch is a smartwatch that does what other devices can't because it's on your wrist around the clock. The key benefits include advanced health monitoring, fitness tracking, safety features, and seamless connectivity — all from your wrist. Apple Watch can track your heart rate, detect irregular rhythms, monitor your sleep, alert you to signs of hypertension, and even detect a hard fall or severe car crash and contact emergency services automatically. As a fitness partner, it tracks every type of workout with advanced metrics and motivates you with Activity rings. And as a communication device, you can make calls, send messages and use Apple Pay — with or without your iPhone nearby. Browse the full Apple Watch Series 11 range at JB Hi-Fi.

Available in 42mm and 46mm in aluminium or titanium. The pick for most people wanting comprehensive health tracking

• Apple Watch SE 3 — essential health and fitness features at a more accessible price. Includes sleep score, sleep apnoea notifications, high and low heart rate alerts and up to 18 hours battery. Available in 40mm and 44mm aluminium. The pick for first-time Apple Watch buyers or those wanting core features without the full price
• Apple Watch SE — a solid entry-level option with essential smartwatch and fitness features at the most accessible price point

Apple Watch Series 11 and Ultra 3 include some of the most advanced health monitoring features available on a wearable device. Cardiologists recognise Apple Watch as a meaningful tool for heart health monitoring — it can generate an ECG similar to a single-lead electrocardiogram, detect irregular heart rhythms that could indicate atrial fibrillation, and notify you of unusually high or low heart rates. Apple Watch Series 11 also introduces hypertension notifications, which can detect signs of chronic high blood pressure over 30-day periods. Additional health features include:

• Sleep score — tracks and rates the quality of your sleep each night so you can identify patterns and improve your rest
• Sleep apnoea notifications — available on Series 11, Ultra 3 and SE 3, detects signs of moderate to severe sleep apnoea
• Blood oxygen readings — available on Series 11 and Ultra 3 for wellness monitoring
• Vitals app — shows overnight health metrics including heart rate, respiratory rate, wrist temperature, blood oxygen and sleep duration in one view
• Cycle Tracking — uses temperature sensors to provide retrospective ovulation estimates for family planning

Apple Watch tracks all the ways you move with Activity rings — Move, Exercise and Stand — which you can customise to suit your goals each day. For workouts, Apple Watch supports a wide range of activities from running, cycling and swimming to strength training, Pilates and yoga, with advanced metrics including Heart Rate Zones, Power and Elevation. Key fitness features include:

• Training load — helps you understand how workout intensity and duration impact your body over time
• Custom Workouts — create interval-based workouts with warm-up, cool-down and recovery periods
• Pacer and Heart Rate Zones — real-time guidance during runs and cardio workouts
• Workout Buddy — powered by Apple Intelligence from your nearby iPhone for personalised coaching
• Offline maps — download hiking routes to navigate without Wi-Fi or mobile signal
• Water activities — Series 11 is rated to 50 metres and supports snorkelling to 6 metres. Ultra 3 is rated to 100 metres and supports recreational scuba diving to 40 metres

Apple Watch includes several safety features designed to help in an emergency. All current models can detect a hard fall and automatically connect you with emergency services and notify your emergency contacts. Apple Watch Series 11 and Ultra 3 can also detect a severe car crash. Additional safety features include:

• Emergency SOS — press and hold the side button to contact emergency services directly from your wrist
• Check In — automatically notifies a friend or family member when you've arrived safely at a destination, or can be started from the Workout app during activities like running after dark
• Satellite emergency SOS — exclusive to Apple Watch Ultra 3, allows you to contact emergency services via satellite when there's no mobile coverage or Wi-Fi

Battery life varies by model. Here's what to expect from each Apple Watch in the current lineup:

• Apple Watch Series 11 — up to 24 hours normal use, up to 38 hours in Low Power Mode. Fast charging delivers up to 8 hours of use from just 15 minutes of charge
• Apple Watch Ultra 3 — up to 42 hours normal use, up to 72 hours in Low Power Mode. Designed for multi-day adventures and endurance events without needing a charge
• Apple Watch SE 3 — up to 18 hours normal use, up to 32 hours in Low Power Mode. Supports fast charging

All models support sleep tracking, which is included within the quoted battery figures above.

Yes. You can send and receive messages directly from your Apple Watch using iMessage and SMS. You can reply using dictation, scribble, emoji, preset replies or Siri — without touching your iPhone. With Apple Intelligence, Apple Watch can also automatically translate incoming messages into your preferred language. On GPS + Cellular models, you can send and receive messages without your iPhone nearby as long as a mobile network is available. On GPS-only models, your iPhone needs to be within Bluetooth range to send and receive messages.

Apple Watch requires an iPhone for initial setup — specifically iPhone 11 or later running iOS 26 or later. Once set up, how much you need your iPhone nearby depends on the model. GPS-only Apple Watch models rely on your iPhone being within Bluetooth range for calls, messages and data. GPS + Cellular models can operate independently from your iPhone for calls, messages, music streaming, app use and emergency services as long as a mobile network or Wi-Fi is available — so you can leave your phone at home. Apple Watch Ultra 3 goes one step further with built-in satellite communications, allowing emergency SOS contact even without mobile coverage or Wi-Fi.

All current Apple Watch models are water resistant, though the rating varies by model. Apple Watch Series 11 and Apple Watch SE 3 are rated to 50 metres under ISO standard 22810:2010, making them suitable for swimming in pools and the ocean, as well as snorkelling to 6 metres. Apple Watch Ultra 3 is rated to 100 metres and supports recreational scuba diving to 40 metres with a compatible third-party app. None of the Apple Watch models should be used for scuba diving below their rated depths, and water resistance can diminish over time.

Yes — GPS + Cellular models of Apple Watch can make and receive calls, send messages, stream music and podcasts, use apps and contact emergency services without your iPhone nearby, as long as a mobile network is available. A carrier plan is required for cellular service. With a carrier plan that supports 5G, you also get faster performance for downloads and app use directly on your watch. GPS-only models require your iPhone to be nearby for calls and data. All GPS + Cellular Apple Watch models are available at JB Hi-Fi across Series 11, Ultra 3 and SE 3.

Both run the same S10 chip and share core features like Activity rings, workout tracking, sleep score, sleep apnoea notifications, high and low heart rate alerts and fast charging. The key differences are:

• Display — Series 11 has a Wide-angle Always-On Retina display at up to 2,000 nits. SE 3 has an Always-On Retina display at up to 1,000 nits without the wide-angle brightness boost
• Health features — Series 11 adds ECG, blood oxygen readings, hypertension notifications, Precision Finding for iPhone and the Vitals app. SE 3 does not include these
• Battery life — Series 11 lasts up to 24 hours (38 hours Low Power Mode). SE 3 lasts up to 18 hours (32 hours Low Power Mode)
• Case options — Series 11 is available in aluminium or titanium. SE 3 is aluminium only
• Size — Series 11 comes in 42mm and 46mm. SE 3 comes in 40mm and 44mm

If comprehensive health monitoring is the priority, Series 11 is the stronger choice. If you want core smartwatch and fitness features at a lower price, SE 3 is excellent value.
