Third-party app support is a standout advantage, especially for Strava, Runna, WorkOutDoors, AllTrails, Spotify, and other Apple Watch apps.

Touchscreen responsiveness evidence is limited but positive, with reviewers reporting responsive interaction and very little latency.

Touchscreen responsiveness receives very strong praise in the Runner’s World review, where the screen is called brilliantly responsive.

The interface is attractive and easy to use in TAG Heuer’s own apps, though broader Wear OS flow is less universally praised.

The user interface is generally smooth and modern, with Liquid Glass and revised workout navigation praised, though minor glitches appear in one review.

Value for money is the clearest tradeoff: reviewers admire the luxury execution but repeatedly say cheaper watches do more for far less.

Value is mixed: reviewers respect the capability but repeatedly mention the high price and limited need to upgrade from recent Ultra models.

Voice assistant support is present and generally useful through Google Assistant, though evidence is limited and not a major focus.

Voice assistant quality is positive, with Siri described as clear and responsive alongside strong speaker and microphone hardware.

Watch faces are a standout feature, repeatedly praised for detail, customization, TAG Heuer identity, and premium always-on presentation.

Watch faces are a meaningful Ultra advantage, especially Modular Ultra and Waypoint, though one reviewer reported Waypoint glitches.

Water resistance is consistently listed at 50 meters or 5ATM, enough for swimming and daily water exposure but not intensive diving use.
