Apple Watch Series 4 40 mm Space Gray GPS + Cellular

This smartwatch pairs with iOS devices and offers cellular connectivity for calls and data without a phone nearby. The 40 mm aluminium case comes in Space Gray. A 1.57 inch Retina OLED display shows notifications and apps. It suits users who want a compact, connected wrist device.

Suits iPhone owners wanting standalone cellular

The watch supports swimproof use up to 50 meters and includes Siri voice control. Buyers who need more than 16 GB of storage for music or apps should look elsewhere. Those requiring a larger case size or a different band width will not find it here. Android users cannot pair this model.

16 GB internal storage decides capacity for apps

The fixed 16 GB flash memory holds the operating system, apps, photos and offline music. No expansion slot exists. If your library exceeds this space, the watch will not fit your needs. Choose a model with higher capacity if you plan large offline collections.

Questions about this item

What does the 1.57 inch screen size mean for daily use on this 40 mm model?

The 1.57 inch Retina OLED display with 394 x 324 pixels fits the 40 mm aluminium case, giving clear text and graphics for notifications, apps and workout metrics at a glance.

How does the USB-A magnetic charger work and what does it limit?

The supplied USB-A magnetic charger connects to the back of the watch; charging speed is capped by the USB-A port and the 291 mAh Li-Ion battery, so a full charge takes roughly two to three hours.

What do I need to mount a band on the 40 mm aluminium case?

The 40 mm case uses Apple’s standard slide-in lugs, so any 40 mm compatible band — sport loop, leather link or metal link — clicks in without tools or adapters.
