Display Comparison

The Ultra boasts a significantly larger 49mm titanium case and a brighter, more durable flat sapphire crystal display with a unique 'always-on' mode optimized for visibility in all conditions. The Series 6 has a smaller 44mm or 40mm stainless steel or aluminum case with a standard sapphire crystal display. The Ultra's display is noticeably more impactful and easier to read outdoors.

Camera Comparison

Neither watch has a front-facing camera. The Series 6 has a rear camera for taking photos and videos, but its quality is limited. The Ultra prioritizes functionality over photography.

Performance

Both watches are powered by dual-core processors, but the Ultra utilizes the newer Apple S8 chip, offering a slight performance edge. However, in everyday use, both watches feel incredibly responsive. The Ultra's enhanced processing power is more noticeable with its advanced features like the depth gauge and more complex workout metrics.

Battery Life

The Ultra offers significantly improved battery life, with Apple claiming up to 36 hours of regular use and up to 60 hours in Low Power Mode. The Series 6 typically lasts around 18 hours. This is a major advantage for the Ultra, especially for multi-day adventures.

Buying Guide

Buy the Apple Watch Ultra if you're a serious athlete, diver, or adventurer who needs a durable, feature-rich smartwatch with extended battery life and advanced sensors. Buy the Apple Watch Series 6 if you want a stylish, capable smartwatch for everyday use, fitness tracking, and notifications, without breaking the bank.
