I Wore a Smartwatch Every Day for Months — It Tracked Everything Except the Number That Mattered Most

I have been wearing a smartwatch on my left wrist every single day for longer than I can remember. Huawei — not the most glamorous brand in the wearable conversation, not the one getting reviewed on YouTube by tech influencers with ring lights and studio setups — but it does everything I need it to do, and it does it consistently without drama.

Every morning it tells me my resting heart rate. Every evening it logs my sleep. And every day it counts my steps, which matters to me because I have a target: 6,000 to 8,000 steps daily. I walk 2 kilometers home from work instead of taking a tricycle. That walk accounts for a significant portion of my count. The watch knows this. It tracks the route, the pace, the heart rate during the walk, and the approximate calories burned.

I look at this data every day. I adjust based on it. I feel like I have a handle on my health.

Then I got my lab results back in March 2026 and my LDL cholesterol came in at 166.54 — above the normal range. Total cholesterol at 242. Both flagged.

The watch did not see that coming. Neither did I.

What a Smartwatch Is Actually Good At

Let me be clear before I go further: I am not writing this post to dismiss wearable technology. I am writing it because I think most people — including me, until recently — have a slightly distorted picture of what these devices actually do well and where their limits are.

Here is what my Huawei smartwatch does genuinely well.

(Not sponsored — but Huawei, if you are reading this, I have been a loyal customer and I walk 2 kilometers every day with your watch on my wrist. Just saying. We are open. 😄)

Step counting and movement tracking. This is the original purpose and it remains the most reliable function. The data is not perfect — no wearable step counter is — but it is consistent enough to be useful. My 6,000 to 8,000 daily target gives me something concrete to work toward, and the watch keeps me honest. On days I skip the 2km walk home and take a ride instead, the numbers show it immediately. That accountability is real and it changes behavior over time.

Heart rate monitoring. My resting heart rate in the morning is one of the first things I check. Over weeks and months, this number tells a story. A consistently elevated resting heart rate can be an early indicator of stress, illness, or overtraining. A gradually improving resting heart rate over time is a sign that your cardiovascular fitness is moving in the right direction. My watch gives me this trend data passively, without me doing anything except wearing it.

Sleep tracking. This one surprises people who have never used it. The watch can distinguish between light sleep, deep sleep, and REM cycles based on movement and heart rate patterns. I cannot verify its accuracy against a clinical sleep study, but I can say that the patterns it shows me align with how I actually feel in the morning. Nights where it logs poor deep sleep are nights where I wake up feeling exactly that way.

Reminders to move. Simple and underrated. After a certain period of inactivity, the watch gives a gentle alert. For someone sitting at a government office desk for eight hours, this prompt is worth the entire purchase price by itself. Sitting for extended periods without movement is genuinely harmful — the research on this is consistent — and having a device on your wrist that nudges you every hour is a cheap and effective countermeasure.

What a Smartwatch Cannot Do

Here is the honest part. The part the marketing materials skip.

My watch cannot measure cholesterol. It cannot check my LDL, HDL, triglycerides, or total lipid profile. It cannot detect that my liver enzymes are elevated or that my blood urea nitrogen is outside the normal range. It cannot tell me that my CBC shows low neutrophils and elevated eosinophils. All of that required a needle, a laboratory, and a doctor reviewing the results.

I wore that watch every single day while my cholesterol was quietly building above the normal range. The watch showed me green checkmarks on my step goals. It told me my heart rate was normal. It logged my 2km walks faithfully. And not once did it flag anything that said — hey, something in your bloodwork needs attention.

This is not a criticism of the technology. It is just the honest reality of what consumer wearables currently are and are not. They measure what sensors on your skin can detect: movement, heart rate, blood oxygen at the surface level, temperature. They cannot see inside your veins. They cannot read your blood chemistry. They are excellent monitors of your daily physical activity and some basic cardiovascular signals — and that is genuinely valuable — but they are not a replacement for actual laboratory diagnostics.

The distinction matters because I think some people — I include myself in this — develop a quiet false confidence from consistent wearable use. The numbers look fine every day, the step goals are being hit, the sleep is tracking reasonably well, so the health system must be running properly. That is not always true. Sometimes the most important diagnostics are the ones happening silently at the biochemical level, invisible to any sensor you can wear on your wrist.

What Makes Sense for Filipinos

Let me bring this closer to home because the wearable conversation is usually framed around Apple Watch prices and Silicon Valley wellness culture, and that framing does not translate well to the Philippine context.

A flagship Apple Watch or Samsung Galaxy Watch will cost you anywhere from ₱15,000 to ₱30,000 or more at full retail. For that price in the Philippines, you can pay for a comprehensive blood chemistry panel multiple times over — the kind that actually tells you what is happening inside your body rather than on the surface of your wrist.

My Huawei smartwatch cost significantly less than either of those options. It does the things I described — step counting, heart rate monitoring, sleep tracking, movement reminders — reliably and without the premium brand markup. For someone in the Philippines who wants the daily accountability benefits of a wearable without spending a month's salary on it, the mid-range options from Huawei, Xiaomi, and similar brands are worth looking at seriously.

The honest recommendation is this: a mid-range smartwatch plus a regular annual blood chemistry panel is a more complete health monitoring system than an expensive smartwatch alone. The watch handles the daily behavioral data. The blood test handles the internal chemistry. You need both. Neither one replaces the other.

MAVS Honest Assessment

I work in IT. I think about systems. I think about data. And the way I now think about my health monitoring setup is this: my smartwatch is the uptime monitor. It tells me the system is running, tracks the daily performance metrics, and alerts me to obvious anomalies. But it is not the deep diagnostic tool. The annual lab panel is the deep scan — the one that goes into the actual processes running underneath the surface and checks things the uptime monitor cannot see.

A server can show 99.9% uptime on the dashboard while a background process is quietly consuming resources and building toward a failure. The dashboard is not lying — those metrics are accurate. But the dashboard alone is not the full picture.

My cholesterol numbers were building quietly while my step count dashboard looked perfectly healthy. The lesson I took from that is not to trust the watch less — it is to use the watch for what it is genuinely good at while making sure the deeper diagnostics still happen on schedule.

Both tools. Not one instead of the other.

The Bottom Line

Wearable technology is genuinely useful. I will keep wearing my Huawei smartwatch every day, tracking my steps, monitoring my resting heart rate, and letting it remind me to stand up and move when I have been sitting too long. That daily data has real value and it has changed my behavior in measurable ways over time.

But I will also get my blood chemistry checked regularly. I will go to the doctor when the numbers come back with something flagged. I will not mistake a clean step count for a clean bill of health.

Your wrist can tell you a lot. Your blood can tell you more. Use both.
