Apple Watch Series 10 GPS 46mm

Apple Watch Series 10 is the thinnest Apple Watch to date at 7.8 mm, and the first to include sleep apnea detection — a FDA-cleared feature that monitors for patterns of disrupted breathing during sleep and prompts you to seek medical evaluation if consistent signs appear over 30 days. This alone makes it one of the most consequential updates since the ECG in Series 4, particularly for a condition that affects an estimated 1 billion people globally who don’t know they have it.

The display is the widest Apple Watch has ever shipped: a 46mm case now shows the same information area as the previous 49mm Ultra. Always-On Retina display at up to 2000 nits outdoors makes it readable in direct sunlight. Depth gauge and water temperature sensor join an already comprehensive health sensor array: optical blood oxygen, electrical heart sensor for ECG, and skin temperature for cycle tracking.

Fast charging brings Series 10 to 80% in 30 minutes — a meaningful improvement for a watch that most people charge beside the bed. Swimproof to 50 metres, the aluminium model is light enough to sleep in comfortably, which is required if you want sleep tracking data. The S9 chip handles Siri queries on-device so you aren’t broadcasting voice commands to a server.

Apple Watch Ultra 2 Titanium

Apple Watch Ultra 2 exists for the edge cases that ordinary smartwatches can’t handle: expedition trekking, open-water swimming, SCUBA diving to 40 metres, and ultra-endurance trail running where you need GPS on your wrist for 60 consecutive hours. The precision dual-frequency GPS (L1 + L5) provides positioning accurate to within 30 cm — meaningful when navigating unmarked terrain where a 10-metre uncertainty is the difference between the path and a cliff edge.

The 49mm titanium case with Corning Gorilla Glass Ultra front crystal is MIL-STD-810H rated for every shock, drop, temperature extreme, and vibration test in the standard. The 3,000-nit display is readable in direct midday sun without shielding your eyes. The Action button on the side is programmable to trigger workouts, dive records, or route waypoints with a single physical press while wearing gloves.

For non-expedition users, the Ultra 2 delivers the same Apple Watch experience with three-day typical battery life, a longer strap range that fits over diving wetsuits, and the loudest speaker of any Apple Watch for emergencies in noisy environments. The siren feature emits a 86dB alarm pattern audible at distance for rescue situations.
