    • Outdoor Workout Measurement Data Collections: Excellent Sensors
Color: Black Titanium Case with Burgundy Trail ... Size: Large Configuration: Without AppleCare+
Review Image by Morgan
This upgrade adds meaningful value to my workout sensor data. I previously used the Ultra 1 and recently moved to the Ultra 4. I ran baseline measurements yesterday, focusing on the two metrics I rely on most: VO₂ Max and HRR. The Ultra 4’s readings matched the Ultra 1 almost exactly, which was a pleasant surprise. The ECG waveform quality is noticeably improved, thanks to the higher sampling rate. I also updated my training zones to reflect my own custom limits and boundaries. The Waypoint display enhances the interface and makes navigation and workout monitoring more intuitive. Battery performance and GPS lock‑on both feel solid, and the display visibility is excellent outdoors. Overall, a well‑executed upgrade and a reliable product. ... show more

    • Bye bye Garmin
Color: Black Titanium w/ Translucent Black Ocea... Size: One Size Configuration: Without AppleCare+
Amazing watch. I used to be a Garmin guy thanks to better metrics for sleep and trading and recovery, but with the Ultra 4 any shortcomings the Apple Watch had are now gone. Tracks my sleep better than my Venu 4 did, I get all of the metrics that matter to me from my sleep and training readiness, and battery life is great. For an Apple Watch. I used to get 12-13 from my Venu 4 so 3-3.5 days from the Ultra 4 is definitely something Apple needs to really try and improve upon further. Super happy with the U4. ... show more

    • Favorite Apple Watch ever.
Color: Black Titanium Case with Burgundy Alpine... Size: Large Configuration: Without AppleCare+
Love this Apple Watch. I’ve had all versions of the ultra and this one by far feels the snappiest and most responsive. The added health features are a plus, and look great on the wrist. The Ultra is the most durable Apple Watch in the series. I would highly recommend this watch if you have an ultra two or below. ... show more
