Product identity and intended user

The Apple Watch Series 9 in 45 mm Midnight aluminium is a GPS-only smartwatch built for iPhone owners who want health tracking, notifications and apps on the wrist without cellular fees. It ships with 64 GB of storage for music, podcasts and offline maps.

Sustained daily performance

A 308 mAh lithium-ion cell powers the always-on 1.91 inch display through a full day of activity tracking, workout sessions and background syncing. The USB-C magnetic fast charger restores the battery quickly between long days, while 50 metre water resistance lets the watch stay on for pool swims and open-water sessions.

Deciding specification

The 484 x 396 pixel always-on retina display is the single detail that determines whether this model fits your wrist and eyesight; the larger 45 mm case and higher resolution make complications readable at a glance compared with smaller variants. Buyers who need a smaller case or cellular connectivity should look elsewhere.
