Google Pixel Watch 4 (45mm)

Why we like it

• Gemini everywhere – Ask questions, set plans, or reply to texts with hyper-relevant quick replies. Gemini runs on-device for personal help even when you leave your phone behind.
• Bigger, brighter domed screen – Actua 360 expands to 45 mm with a 10% larger surface and 50% more brightness outdoors, while Gorilla Glass keeps it durable.
• Battery gains + side dock – Expect about 30 hours per charge (48 with Saver) and top up fast with the new side dock that gives ~15 hours of juice in 15 minutes.
• Best health stack Pixel’s offered – Dual-frequency GPS keeps routes true, 40+ exercise modes deliver real-time metrics, and Loss of Pulse Detection plus satellite SOS add extra safety.

Setup tips

1. Update the watch and install the Google AI updates right away—Gemini features unlock after the first sync.
2. Set the new side dock near your desk so 10–15 minute top-ups become a habit; it uses pogo pins so you can charge while glancing at the screen.
3. In the Google Pixel Watch app, enable Loss of Pulse Detection and satellite SOS for emergency routing.
4. Customize the quick replies for messaging so Gemini can slot in your tone automatically.
