Apple Watch Series 6 Review: Is the Blood Oxygen Sensor Still Useful Today

Living With the Apple Watch Series 6 on My Wrist

My first days getting used to the Apple Watch Series 6—the red one, which I found strikingly different—sparked an odd mix of anticipation and gentle caution. Unlike previous devices, this one immediately became a sort of anchor on my wrist: always humming, always ready, sometimes too ready. I found the always-on display disrupted that experience in both subtle and overt ways. Sometimes, it felt like my attention was divided in a way that only a persistent piece of technology can manage.

The real tension for me arrived before even strapping it on: Did I really want another screen in my day-to-day flow? I already had my phone nearby and didn’t quite know if yet another device would add clarity or siphon away more focus. Having the Series 6 on hand soon revealed that these decisions are rarely black-and-white. As I wore it, the distinction between convenience and distraction grew blurrier, and I became more aware of how often I was looking down for another notification.

Moments of Utility and Moments of Pause

Each morning, I tried to let the Watch’s health metrics slip quietly into my routine. The blood oxygen monitoring feature—new to this model—caught my attention only when I remembered to check it. Was it essential? Not for me, at least not yet. I started tracking my sleep out of curiosity, only to realize my sleep quality wasn’t always improved simply by knowing the numbers. There are insights the Watch can provide, but their impact hinged on how I chose to act on them, or sometimes whether I even cared.

One thing that surprised me was the low-key pressure that came with the Rings. Those ever-present reminders to stand, move, or close some imaginary circle introduced both moments of motivation and moments of fatigue. I realized I liked the gentle buzz nudging me out of my seat but also sometimes resented how calculated it all felt. I could ignore those notifications, of course, but the feeling lingered: Was I wearing this to be more present, or was it one more way to measure myself?

The Subtler Negotiations With My Time

Notifications and calls became more intimate, and I noticed my relationship with interruptions subtly shifting. On one hand, I loved that I didn’t need to pull out my phone for every little thing—texts, calendar nudges, and app pings showed up right there. On the other, I found myself glancing at my wrist more than ever before, and sometimes it felt like a polite way to escape a moment, other times just an automatic reflex. ⌚️

To my surprise, quick responses using pre-set messages or dictation added a layer of efficiency I hadn’t counted on. But efficiency isn’t always clarity. Short replies became the norm, even when longer, more thoughtful ones might have served me better. My social rhythms felt changed—briefer, maybe even a bit truncated. It made me think: was this the Watch helping my day, or compressing it too much?

• I could check messages discreetly but sometimes worried about seeming distracted.
• The blood oxygen readings felt reassuring, yet I wondered how actionable the insights were for me personally.
• Using Apple Pay from my wrist sped up daily errands, but it wasn’t essential for every outing.
• Battery life always seemed “enough” but not effortless—I was frequently calculating when to recharge, which occasionally interrupted my rhythm.
• Customizing faces made things feel personal, but too many choices sometimes delayed my setup in the morning.

Fitness Nudges Versus Genuine Motivation

There is a strange comfort in having health metrics so accessible, but that comfort isn’t universal. I noticed some days I would get caught up in the daily goal—move more, stand up, breathe—and other days that very feedback felt burdensome. I wasn’t always sure which version of myself would show up: the one who appreciated the “keep moving” reminders, or the one who found them overbearing. This ever-present feedback loop sometimes motivated me, but occasionally made me feel watched rather than supported. 🏃‍♂️

During brisk walks, the Watch tracked my progress with satisfying consistency, but I realized I placed more value on the sense of accomplishment than on the numbers themselves. When I relied on it too heavily for encouragement, it began to feel transactional. I liked the validation, but also wished the sense of progress could be more intrinsic—coming from within, rather than from a wrist-bound digital coach.

One subtle observation: the data felt richer than my willingness to interpret it. Some nights I’d browse my heart rate history or sleep data, only to lose interest halfway through. There’s a lot to glean, that’s true, but only so much attention to spare.

Battery Awareness and Charging Patterns

If I’ve developed a new reflex since using the Series 6, it’s the ever-present question of battery percentage. Charging didn’t become a chore, exactly, but I could never ignore it. I caught myself checking the green lightning symbol before heading out, always bargaining with how long the Watch might last until I’d be near a charger again. This small negotiation was sometimes a reminder that technology promises autonomy but quietly asks for commitment. 🔋

Sleep tracking drew attention to this trade-off—if I wore the Watch all night, I’d need to find time the next day to top up. Sometimes this fit naturally into my schedule, other times it felt like an inconvenient shuffle. I wouldn’t call it a deal-breaker, but I also couldn’t ignore how these little logistical hiccups shaped my day.

Privacy, Security, and My Own Boundaries

Glancing at health stats, responding to texts, and viewing notifications without pulling out my phone added up to a strange new proximity to my digital life. The authentication for Apple Pay and unlocking my Mac was satisfying, smooth, and speedy—but also brought to mind questions of privacy that I didn’t always want to dwell on.

Even though I trusted the security measures, I felt the differences between the privacy afforded by a phone versus a watch. The Watch’s presence on my wrist made every alert more visible to me, but also potentially more visible to those nearby. At times, that made me rethink what I wanted to see immediately and what could wait.

I also considered how health data collected here might be used in the long run. While the Series 6 never pushed me into uncomfortable territory, I remained aware that data is rarely inert, and wondered about the boundaries I’d set for myself now and down the road. 🤔

Decisions, Expectations, and My Own Rhythm

Living with the Series 6 didn’t answer all my questions about how tightly I want to weave technology into the rhythm of my day. I kept balancing the promise of efficiency and health insights against the subtle weight of expectation that another smart device brings.

I found myself negotiating the value I placed on certain conveniences. Sometimes the Watch made these decisions seamless; other times, it felt like one more thing to calibrate or silence. The more I used it, the more I realized that no single device—however smart—replaces intention or self-awareness. There are times when I relished the simplicity it brought, and other times when I missed the quiet space found in not knowing or not being reminded.

It’s hard to sum up the experience as right or wrong. Instead, I’m left reflecting on how every new gadget quietly changes the texture of ordinary moments. The Apple Watch Series 6 made certain small tasks easier, but also called more of my attention to the surface. That’s not inherently good or bad—just something I continue to notice, and occasionally question, as I move through each day with a device that’s sometimes helper, sometimes distraction, and sometimes just there, gently vibrating, nudging me along. 🧭
