Ultra Series

I’m not as hardcore as you. Doing fairly intense, compared to the average 71 year old, but I do exercise very rigorously for over an hour everyday. I’m tracking what is happening especially for endurance in improving general health and stamina. I do pool exercise and needed to have a watch that could last 6 to 8 hours per week every week. I went through my Series 6 with 5 replaced watches (I kept AppleCare) every year. So the Ultra Series has better water redistance and battery life. In can appreciate your comment about heart rate. I have seen problems with outlier measurements. There are one or two times, very intermittent. I’ll get a recorded heart rate reading about double the rest of the recorded HR. My anecdotal observation is it tends to happen in the pool. If I see the reading I will tighten the bad a bit and it doesn’t seem to continue. This happened on my old Series 6 and it has happened on my Ultra 3. It probably comes down to the intent of the design combined with the use case. If I go to my doctor every office visit begins with vitals being taken. It’s a snapshot in time. If a reading is about of whack they may repeat it in a few minutes once or twice, another slice of time. All Apple Watch products are really good at monitoring trends over time. You can setup alerts snd there are apps that can do additional analysis using the collected data. I look at trends events there too low and too high. The outliers do not really impact trend data. The other thing about trend data is knowing when your trend data occurs. I had a heart rate that would go below 40 bps in the 15 to 30 minutes before I wake-up in the morning. I got an alert that I was able to tell that to my Primary doc and Cardiologist. They suggested a change that needed to monitor for another couple of weeks. In my use case, the heart rate monitoring capability is 100% effective. It’s so effective I have the entire days HR data displaying in a compilation a full view of yesterday’s data and to date of the current day. Tap the graph and I can drill into the data, even the outline events. I’m not sure if the watch face comes from the heart health app I have or it’s in the Apple Watch stock watch faces. I have been enrolled the multi-year Apple Heart & Movement Study. The study has found that the Apple Watch sensor is accurate to within 5 bpm (beats per minute) for 98% of the time when users are in sedentary (or resting) mode, and reaches 99.7% accuracy with an error margin of 10bpm. The sensor’s heart rate accuracy varies: * 96% for outdoor cycling, * 87% while walking, * 88% while running, and * 91% during high-intensity workouts, with a 5 bpm error margin when recording in the foreground. Starting with the Apple Watch Series 6, accuracy has improved significantly. * Data from 480 participants logging 21,000 hours shows 89% accuracy (within a 5 bpm error margin) in the background, compared to 72% in older models.

I only dive 3-4 times a year, and my AWU2 is great for my needs. With AOW dives, I’m not going past 30m. Since there’s always some nonzero risk of an accident causing my depth to dip below the AWU max of 40m, I do eventually plan to have a backup dive computer with me just in case my AWU fails, but it’s been perfect for me so far. If you already plan to have an Apple Watch for daily wear, and also need a dive computer for occasional recreational dives, I think it’s a great option. The colour display with high brightness is something that I was not able to find at a similar price point for a dive computer that also functions as a daily smartwatch.

I’m using a awu 1 and a tactix 8 for work

I got the Apple Ultra 3 . And not impressed. When i have to start a run i need to do three taps. Is Garmin going to be better. I also play tennis . And walk. I need something thst wint need me to be constantly tapping etc . Am I expecting too much.

I’ve been using the Ultra 3 for about a week now, mainly for running (1–2 hours a day, roughly 10h/week, 120km/week) plus strength training or yoga for about an hour daily. I’m very routine-driven: I work from home, never travel much, always home by 6PM, runs in the morning, workouts in the afternoon. So my habits are pretty consistent. # 🔧 Settings * Always-On Display: **ON** * Cellular: **ON** (outdoors only) * Low Power Mode: **OFF** * Background Refresh: **ON** (disabled a few irrelevant apps) * Wake on Wrist Raise: **OFF** * Wake on Crown Rotation: **OFF** * Always On: **ON** # ⚡ Charging & Battery I keep it between 20–80% charge, and it tops up super fast — basically full again after my post-run shower. On average, I’m getting about **1.5 days per charge**. I typically charge it every other day: once in the evening and then again after my morning run two days later. It’s nowhere near Garmin-level battery life, but I honestly don’t mind the shorter cycle. A single 1–2h run eats up about **7%**, regardless of whether cellular is on or off. I don’t play music from the watch since I usually have my work phone on me and stream to my Shokz from there anyway. # ❤️ Heart Rate Accuracy This is where the Ultra still lags behind Garmin. * For walking, strength, or yoga — it’s great, very close to chest HRM accuracy. * For running — not so much. I get frequent dropouts and it often locks to cadence (hello, 180 bpm “steady state”). I’ve tried all the usual fixes — moving it higher up my wrist, tightening/loosening, different bands — no real improvement. I have a pretty bony wrist, so that might be part of the issue. My Garmin’s optical sensor wasn’t perfect either, but at least it didn’t constantly confuse cadence for HR. I’ve switched to a chest strap again for running sessions. # 📊 Metrics & Health Data Coming from Garmin, this is the weakest point. Apple’s HRV, stress, and recovery data are nowhere near as consistent or detailed. HR and HRV aren’t continuously measured, so you lose that nice rolling insight Garmin gives you. That said, after three years with Garmin I’ve learned my own recovery cues pretty well — so I’m less reliant on the watch’s “readiness” metrics now. There are third-party apps that try to replicate Garmin’s body battery / training load data, but without continuous measurement, it’s just not the same. # 🍏 Ecosystem & Everyday Use This is where the Ultra wins easily. * The UI is smooth and snappy. * Being able to respond to messages and notifications without my phone is huge. * Integration with the rest of Apple’s ecosystem (Mac, iPhone, AirPods) is seamless. If you’re already deep into Apple’s world, the watch feels like an extension of your digital life. # 🆚 Apple Watch Ultra 3 vs Garmin Garmin is still **the better athlete’s watch**, no question — especially for long-distance runners or anyone training for ultras. Battery life, GPS tracking, and data depth are all superior. This is why I will still keep my garmin - for any 50k+ mountain runs. I am just not this kind of guy who would turn all the settings off, making the watch essentially pointless (I like looking up metrics during run a lot). But if you’re like me — training \~20 hours a week (which is still only about 18% of my waking time) — the other 82% of your life is where the Apple Watch shines. For everything outside pure training, the Ultra 3 is just **a better all-around smartwatch**.

Thanks for the input on this - makes me wonder whether I have a faulty model :) But again - works quite well when I don't move a lot.

Switch from Apple Ultra Watch 2, etc. to Balance 2 XT. With Gadget Bridge and GrapheneOS, I’m very happy.

I had an Ultra 2 which I bought for the cell feature and Spotify. That worked intermittently the entire time I had it. It wouldn’t even play downloaded music correctly most times. I even paid for an Apple Music subscription thinking it would be better. It wasn’t. I did use it as my only watch for about 6 months and it was pretty good but charging every other day got old and the battery got pretty bad after 18 months or so. I sold it when the 970 came out. I would add that I do not pay attention to any of Garmins useless training stats and algorithm junk that people seem to love so much. I just want a watch that’s accurate and easy to use. You can do worse. But. It’s just not as good as a Garmin for triathlon. You know it’s not. You’re hoping someone will convince you otherwise.

I ran both a 955 and a AWU2 for a year. Used my Garmin for racing, used my AWU2 for swimming and running (using native app for swimming and WorkOutdoors for running) and a Garmin Edge 1050 for biking (indoors and out). I ended up ditching my AWU2 when the cell signal became so jenky and limiting that I was forced to download music before running, making half the use case for the watch useless. I only intermittently had cell service with it, so for biking I had to carry my phone anyway. I ran a sub 4 hour marathon with the AWU2 (charged to 100% morning of, turned off nothing) and I was at less than 40% battery at the end, so I question if it could really last a full IM even in battery saver mode. The battery was excellent when it was new, 18 months later I wasn’t getting two days including workouts. I now have a 970 and it’s wonderful. The AW is excellent, but I just got tired of having two devices and the cell service on the AW was so spotty I gave up on it. Lastly, the “metrics” that Garmin gives you are pretty stupid. Listen to your body, not some silly watch that says you should or shouldn’t train. Having 2 watches isn’t a big deal from that standpoint. If you are letting an algorithm determine your ability to do things, you’re doing it wrong. It can be a guide. It is not the answer.
