Apple Watch Series 3 Aluminium "38 mm" GPS Specs

Apple Watch Series 3 - MQKU2LL/A - Watch3,3 - A1858

About This Watch

The Apple Watch Series 3 is almost identical in its shape and form to its predecessors but has been fitted with upgraded and more powerful internals. Whilst the battery and many other components stayed the same, the most notable upgrades are the new Apple S3 processor and the ability for certain watches to be connected to a 3G network. This allows for the watches to be fully functional without needing to be tethered to an iPhone. This functionality is not present in the GPS only variants but is present on the cellular variants. The watches function off a partnered SIM card which needs to be purchased with the same mobile carrier as your phone. 

Storage & Memory

The Apple Watch Series 3 comes with 768 MB of RAM and 8 GB of memory. Apple has not released official specifications on song and photo storage capacities.

    Screen Size and Resolution

    This Apple Watch Series 3 has a 38 mm sized OLED display with a resolution of 272×340. This display is force touch capable and also has a water resistance protection of an estimated 50 meters.

      The Apple Watch includes the following features:

      • Force touch OLED display.
      • Digital crown control piece.
      • Multiple wristband units.
      • Heart-rate monitor.
      • Emergency heart-rate detection.
      • Wireless Charging.
      • Bluetooth.

        The Apple Watch Series 3 comes with the newly introduced Apple watchOS 4 for its operating system. It is also powered by a dual-core Apple S3 processor. Apple has not released processing speeds for this processor.
