Apple Watch Series 12 & Ultra 4: What's New in 2026

Apple Watch Series 12 & Ultra 4

A smarter health sensor, a new chip, and the same $399 starting price. Here's what's new.

Apple's newest smartwatches are official. The Apple Watch Series 12 and rugged Ultra 4 arrived alongside the new iPhones, and the headline is health: a dramatically more frequent heart-rate sensor. Here's what's new — and how to get a certified Apple Watch that covers the essentials for a lot less.

What's new in the Series 12

New S11 chip: faster and more efficient performance.
Health Sensing System: reads your heart rate far more often than before for richer health and workout data.
Ceramic case option: a premium third material alongside aluminum and titanium.
24-hour battery rating, 5G-capable cellular, and fast charging.
Same $399 starting price as the Series 11.

The Ultra 4 carries the rugged, adventure-focused torch for hikers, divers, and endurance athletes.

Do you need the newest one?

The Series 12's health upgrades are genuinely nice — but for most people, a recent Apple Watch already nails the essentials: activity tracking, notifications, workouts, heart-rate monitoring, and Apple's best-in-class ecosystem features. If you want top-tier and adventure-grade, a certified Apple Watch Ultra 2 delivers a premium experience for well below a new flagship.

Get adventure-grade for less: a certified Apple Watch Ultra 2 gives you a rugged titanium build, huge battery, and precision GPS from $559.99 — a fraction of new-flagship money.
