Is your Apple Watch Ultra
authentic?
The Apple Watch Ultra is Apple's most expensive and advanced smartwatch, with a rugged titanium design for extreme sports and diving. Counterfeit versions attempt to mimic the distinctive orange Action Button and titanium case but lack the advanced sensors and build quality.
How to authenticate an Apple Watch Ultra
Titanium Case Construction
The Apple Watch Ultra uses a 49mm aerospace-grade titanium case with a brushed finish and polished chamfered edges. The case should feel substantial (weighing 61.3g without a band) and have a uniform matte gray color. Counterfeit watches use painted aluminum or low-grade alloy that feels lighter and has uneven finish quality.
Action Button Function
The orange Action Button on the left side of the case is a customizable physical button with haptic feedback. Press and hold it to trigger your chosen action (workout start, waypoint, flashlight, etc.). It should provide tactile confirmation and launch the action instantly. Counterfeit watches have fake orange buttons that don't work or lack haptic feedback entirely.
Dual-Frequency GPS
The Apple Watch Ultra features L1 and L5 dual-frequency GPS for precision tracking in challenging environments (dense urban areas, forests, mountains). To verify, go on a GPS-tracked outdoor activity and check for accurate route logging. Counterfeit watches use single-frequency GPS chips that drift significantly in urban canyons or under tree cover.
Depth Gauge & Water Temp Sensor
The Apple Watch Ultra includes a depth gauge (0-40 meters) and water temperature sensor for diving. Open the Depth app to see real-time depth readings when submerged. It's EN 13319 certified for recreational scuba diving to 100 meters. Counterfeit watches lack these sensors entirely—the Depth app either won't exist or will show fake static data.
Serial Number Verification
Go to Settings > General > About to find the serial number. Verify it at checkcoverage.apple.com—a genuine Apple Watch Ultra will show "Apple Watch Ultra" as the model along with warranty status. The Ultra was first released in September 2022, and Ultra 2 in September 2023. If the serial shows a different model or isn't recognized, it's counterfeit.
86-Decibel Siren
The Apple Watch Ultra includes a built-in 86-decibel siren for emergencies. Press and hold the Action Button to activate it (if configured). The siren produces a loud, distinctive two-tone pattern audible up to 180 meters away. Counterfeit watches either have no siren functionality or a weak speaker that can't produce the required volume.

Action Button Doesn't Work
If the orange Action Button on the left side of the case doesn't respond, doesn't provide haptic feedback, or is just a decorative orange piece of plastic, it's a fake. The genuine Action Button is fully programmable and provides distinct tactile confirmation when pressed.
Case Feels Too Light
The Apple Watch Ultra case weighs 61.3g (without band) due to the solid aerospace-grade titanium construction. If the watch feels unusually light or hollow, it's using a painted aluminum or cheap alloy case. Authentic titanium has a distinctive weight and cool-to-the-touch feel.
Depth App Missing or Non-Functional
The Apple Watch Ultra has a dedicated Depth app that shows real-time depth and water temperature when submerged. If this app is missing, doesn't launch, or shows fake static data (e.g., "0.0m" when underwater), the watch lacks the required depth gauge sensor and is counterfeit.
Display Not Flat Sapphire
The Apple Watch Ultra uses a flat sapphire crystal front (not curved like standard Apple Watch models). If the display is curved, has a plastic feel, scratches easily, or lacks the hardness of sapphire, it's a fake. Sapphire is second only to diamond in hardness and resists scratching from metal and sand.

Frequently asked questions
What makes the Apple Watch Ultra different from other Apple Watch models?
The Apple Watch Ultra features a 49mm aerospace-grade titanium case (larger and more durable than aluminum or stainless steel models), a flat sapphire crystal display, dual-frequency GPS (L1 and L5), a customizable Action Button, a depth gauge and water temperature sensor for diving, and a much larger battery providing up to 36 hours of normal use or 60 hours in Low Power Mode.
How deep can the Apple Watch Ultra go underwater?
The Apple Watch Ultra is water resistant to 100 meters (WR100) and EN 13319 certified for recreational scuba diving. It includes a depth gauge that measures down to 40 meters and a water temperature sensor. The Depth app provides real-time dive metrics. Counterfeit watches do not have functional depth gauges or temperature sensors.
What is the Action Button on Apple Watch Ultra?
The Action Button is an orange, customizable physical button on the left side of the Apple Watch Ultra case (opposite the Digital Crown). You can program it to launch apps, start workouts, mark waypoints, activate the flashlight, or trigger other actions. It provides tactile haptic feedback when pressed. Counterfeit watches either lack this button entirely or use a non-functional decorative orange button.
