Apple Watch Series 12 • 46 mm GPS + Cellular • M/L
Deep blue. A broader view.
A polished Night Blue ceramic case and Navy Blue Sport Band bring a distinctive finish to this larger Apple Watch Series 12. Its 416 × 496-pixel Always-On Retina display makes room for activity, messages and overnight trends, with S11 processing and cellular hardware for a supported mobile plan.

Night Blue ceramic
A polished finish. Room to see more.
The larger 46 mm size category uses a ceramic enclosure measuring 47 × 41 × 9.85 mm, weighing 52.9 g without the band. Night Blue ceramic is paired with a Navy Blue Sport Band in M/L. Sapphire front crystal protects the 416 × 496-pixel display, with 1196 mm² of viewing area, wide-angle OLED and LTPO3. Always-On Retina presentation ranges from a 1-nit minimum to 2000 nits peak brightness.
S11 and controls
Small movements. Useful shortcuts.
S11 uses a 64-bit dual-core processor alongside a separate four-core Neural Engine and 64 GB of storage. A haptic Digital Crown, side button and supported single-tap, double-tap and wrist-flick gestures offer different ways to interact. Speaker, microphone and media playback are built in. Siri and AI-related functions depend on software, language, region and supporting setup; no universal entitlement is implied.
Health-sensing system
See patterns with the right context.
The Series 12 model family combines electrical and optical heart sensing with blood-oxygen and temperature sensors. Heart Rate, ECG, Blood Oxygen, Vitals, Readiness and Recovery HRV functions have different setup and eligibility requirements. Sleep, heart-rate, irregular-rhythm, sleep-apnoea and hypertension notifications are also software- and region-dependent. These tools do not provide a complete medical assessment or replace professional diagnosis; exact South African feature availability must be confirmed.
Activity and recovery
Balance effort with the bigger picture.
Activity rings, custom workouts, training load, heart-rate zones and outdoor navigation support a varied routine. Built-in L1 GPS works with GLONASS, Galileo, QZSS and BeiDou; a compass and always-on altimeter add direction and elevation. The family feature illustrations show Readiness, HRV and sleep views, sometimes on different finishes. Their presence does not guarantee every feature on the supplied software or any particular training outcome.
GPS + Cellular
Keep in touch, within coverage.
The A3587 model family includes LTE and 5G RedCap hardware, 2.4/5 GHz Wi-Fi 4, Bluetooth 5.3 and second-generation Ultra Wideband. With a supported mobile plan, calls and messages can work away from your iPhone. Apple lists MTN and Vodacom for South African Apple Watch cellular service; confirm the exact plan, activation, model and coverage with the carrier. Radio-band support alone does not guarantee 5G service, roaming or independent emergency access.
Safety and shallow water
Practical tools, clear limits.
Fall Detection, Crash Detection, Emergency SOS, Check In, Backtrack and the last emergency-call-availability waypoint support everyday safety. They depend on setup, networks and regional availability and cannot detect every incident or guarantee a response. The 50m water-resistance rating is for shallow-water activities, not scuba diving or high-velocity water. A 6m depth gauge and water-temperature sensor do not change that limit. IP6X dust resistance and water resistance are not permanent.
Battery and charging
Make charging part of your rhythm.
Apple rates Series 12 for up to 24 hours of normal use or up to 38 hours in Low Power Mode under its test conditions. Fast charging can reach about 80% in 30 minutes with appropriate equipment. Real runtime and charging depend on connection, activity, settings, temperature and accessories. The supplied 1m magnetic fast-charging cable ends in USB-C; a separate compatible power adapter is required.
Navy Blue Sport Band • M/L
The specified finish, ready for setup.
This configuration pairs Night Blue ceramic with a removable Navy Blue Sport Band in M/L. The specified package contains the watch, band and 1 m Magnetic Fast Charger to USB-C cable. Apple’s current global Series 12 specifications require iPhone 11 or later, including iPhone SE second generation or later, with iOS 27 or later. Confirm the installed watchOS, exact band fit, regional feature availability and local warranty entitlement for this AF/A configuration.
