Dimensions and Physical Specifications of the Apple Watch Ultra

The Apple Watch Ultra is designed as a robust and larger alternative to the standard Apple Watch models, catering especially to outdoor enthusiasts and professionals who require enhanced durability and functionality. It features a significantly larger and thicker case to accommodate additional hardware, such as a bigger battery and more advanced sensors.

The case size of the Apple Watch Ultra measures 49mm, which is notably larger than the sizes available for the standard Apple Watch Series models. This increased size impacts both the overall footprint on the wrist and the display area, providing more screen real estate for complications, notifications, and app interfaces.

Key physical specifications include:

  • Case Size: 49mm (height)
  • Thickness: Approximately 14.4mm, making it thicker than standard models to house enhanced components
  • Weight: Heavier than standard watches due to the titanium case and larger battery, typically around 61.3 grams (GPS + Cellular version)
  • Material: Aerospace-grade titanium, contributing to both durability and a premium lightweight feel

This combination of size and materials ensures the watch is rugged enough for extreme conditions while maintaining a relatively comfortable wear for extended periods.

Display Size and Resolution

The Apple Watch Ultra features a larger display than previous models, which improves visibility and usability especially during outdoor activities where quick glances are necessary. The display is a flat sapphire crystal screen, enhancing scratch resistance and durability.

The display specifications are as follows:

  • Screen Size: 1.92 inches (diagonal)
  • Resolution: 410 x 502 pixels
  • Brightness: Up to 2000 nits, which is significantly brighter than standard Apple Watch models for better outdoor readability

The increased resolution and size allow for more detailed watch faces, larger touch targets, and enhanced complication layouts, making it ideal for users who rely on quick data access without sacrificing clarity.

Size Comparison with Other Apple Watch Models

To provide a clearer perspective on how the Apple Watch Ultra compares in size to other models, the following table outlines the key size differences:
