Red aluminium case for iPhone users

This Apple Watch Series 9 in red aluminium pairs with an iPhone to deliver calls, messages and Siri voice control from the wrist. The 45 mm case holds a 1.91 inch always-on display at 484 x 396 pixels. Built-in GPS and cellular let you leave the phone behind while staying reachable. It suits anyone who wants a fully connected watch in a compact, lightweight design.

Swimproof to 50 metres with magnetic USB-C charging

Water resistance rated to 50 metres supports pool swims and open-water sessions without worry. The Li-Ion 308 mAh battery charges via the included USB-C magnetic fast charger for quick top-ups. Normal daily use runs cool and silent with no audible fan or moving parts. Haptic feedback on the Digital Crown adds tactile response without extra power draw.

64 GB storage frees wrist space for apps and music

Onboard 64 GB flash storage holds offline playlists, podcasts and apps so the watch works independently of the phone. iOS compatibility is required for setup and ongoing sync. The 45 mm band size fits a wide range of wrists using Apple’s standard quick-release mechanism. Buyers who need more onboard storage or Android pairing should consider other platforms.

Questions about this item

How do I attach the 45 mm band and what step do people miss?

Slide the band into the case grooves until you feel a click on both sides; the step people miss is pressing the release button fully before pulling the old band out.

What will need replacement after a couple of years of daily charging?

The non-removable 308 mAh Li-Ion battery will eventually hold less charge and requires professional service to replace.

How long can I swim continuously before the 50 m water-resistance limit becomes a concern?

The watch is rated for 50 m depth, not time; rinse it after each swim and avoid high-velocity water to keep the seals intact.
