OPPO Watch S Review: This RM799 Watch Has No Business Looking This Good

I’ll be honest with you. I currently own five smartwatches. Five. And yet, every single morning when I grab my keys and head out the door, I find myself reaching for the OPPO Watch S. That says a lot, and I think that pretty much sets the tone for this review.

The OPPO Watch S is priced at RM799, and it targets people who want something that looks premium, tracks health seriously, and doesn’t demand to be charged every other night. Does it deliver? Let’s get into it.

Design & Build

First impressions matter, and the OPPO Watch S nails it. The stainless steel case is slim at just 8.9mm thick and weighs only 35g without the strap, which means you genuinely forget it’s on your wrist. No awkward bulk sticking out from under your sleeve, no pressure on the wrist during sleep. It just sits there, doing its job quietly.

It comes in two colours, Phantom Black and Silver Gleam. My unit came in Silver Gleam paired with the woven nylon strap, and this combo might just be one of the best-looking smartwatch pairings I’ve seen at this price range. The green, blue, and yellow stripe on the canvas-style strap gives the OPPO Watch S this trendy, almost sporty vibe that somehow still looks put together enough for the office. I’ve worn it to casual Friday meetups, early morning runs, and even a client dinner, and it held its own in every setting.

There are two strap options available: a sporty fluoroelastomer rubber band that’s sweat and water resistant, and the breathable woven nylon that I’ve been using. Both are easy to swap out and genuinely comfortable for all-day wear.

On durability, OPPO isn’t messing around. You get 5ATM water resistance rated to 50 metres, IP68 dust and water protection, and it has reportedly passed military-grade durability testing. Whether you’re swimming laps, caught in a sudden downpour, or just going about your sweaty gym session, this watch can take it.

Display

The 1.46-inch round AMOLED display is gorgeous. Running at 464 x 464 resolution at 317 PPI, everything on screen looks sharp and detailed. The AMOLED panel does what it does best: deep blacks, punchy colours, and animations that feel fluid. Scrolling through menus and watch faces just feels satisfying.

Brightness is where this display really stands out. Default brightness is 600 nits, which is perfectly readable for most indoor and everyday scenarios. Crank it up to high brightness mode and you get 1,500 nits. But the real headline? During outdoor workout mode, when the watch detects strong sunlight, it can push all the way up to 3,000 nits automatically. That’s on par with the Apple Watch Ultra 3, on a RM799 watch. Reading your pace data mid-run under bright afternoon Malaysian sun? Zero squinting required.

You can also enable always-on display mode, though it does take a hit on battery life as expected.

Health & Fitness

This is where the OPPO Watch S really earns its keep. The sensor package is genuinely impressive, featuring an 8-channel optical heart rate sensor, a 16-channel optical blood oxygen (SpO2) sensor, ECG electrodes, and a wrist temperature sensor.

The ECG feature is one I use pretty regularly. It’s a quick way to check my own heart rhythm and flag anything that looks off. I’m not a doctor, and neither is the watch, but having that data on hand and being able to share it with my physician is actually useful. It’s the kind of feature you’d expect on much more expensive devices.

For daily health tracking, you get continuous heart rate monitoring, all-day SpO2 readings, and wrist temperature trends. The 60-Second Wellness Overview pulls together nine health metrics including heart rate, blood oxygen, stress level, temperature, and sleep history into one quick snapshot. It’s like a morning health briefing right on your wrist, and I genuinely find it useful before I start the day.

Sleep tracking is comprehensive too. The watch monitors deep, light, and REM sleep stages alongside respiratory rate and sleep SpO2 levels, then gives you a sleep score with suggestions for improvement. There’s even a snoring risk assessment built in, which, depending on how your partner feels about your sleeping habits, might be either very useful or slightly terrifying.

On the fitness side, over 100 sports modes are supported, with six of them including running, cycling, and swimming being detected and started automatically. The dual-band L1+L5 GPS is accurate for outdoor tracking and covers GPS, BeiDou, Galileo, GLONASS, and QZSS satellite systems.

Running gets the most depth here. You get fat-burn zone tracking, running posture analysis, and even estimates for lactate threshold and VO2 max. Those are metrics you’d normally only find on dedicated sports watches that cost way more. For badminton players and tennis folks, there’s a racket sport mode that tracks shot distribution, swing speed, and heart rate zones throughout a match. Wear it on your racket hand and you get a proper performance breakdown after your session.

Watch Faces

The watch face selection is genuinely good. There are hundreds to choose from across different styles, from clean analogue designs to data-heavy digital layouts and everything in between. Most of them lean on the cleaner, more elegant side of things which I appreciate. Nothing too busy or garish. I have a few personal favourites saved, and swapping between them depending on my mood or outfit for the day has become a small but enjoyable habit.

You can also customise the watch face using photos from your personal gallery, which is a nice personalisation touch.

Battery Life

One of the biggest selling points of the OPPO Watch S is battery life, and in my experience, it genuinely delivers. OPPO claims up to 10 days on a charge with standard settings. In real use with health monitoring, GPS workouts, sleep tracking, and notifications all running, I comfortably got over a week. There were stretches where it stretched close to two weeks on standby. That’s the kind of battery life that makes you completely stop thinking about charging, and for a smartwatch, that’s huge.

The charging speed is also excellent thanks to VOOC 2.0 fast charging. Ten minutes on the charger gives you roughly a full day of use. A complete top-up from flat takes under 90 minutes. So even if you forget to charge overnight, a quick plug-in while you’re getting ready in the morning is all you need.

If you enable always-on display, expect around four days of battery life instead. Still not bad.

Smart Features

The OPPO Watch S runs on ColorOS Watch, OPPO’s proprietary smartwatch platform. It’s clean, responsive, and easy to navigate even if you’ve never used a smartwatch before. Bluetooth 5.2 keeps it connected to your phone, and you can make and receive calls directly from the watch via Bluetooth calling. NFC is on board too, though contactless payment support will depend on regional availability and your bank.

There’s 4GB of onboard storage for offline music, and one of the more useful features is cross-OS dual-phone pairing. The OPPO Watch S can connect to two phones simultaneously, whether that’s two Android phones or one Android and one iPhone. Super handy if you’re carrying both a work and personal phone.

The one notable limitation is the absence of WearOS support. That means no Spotify, no Strava, no Google Maps on your wrist. OPPO does offer workarounds, like manually loading music onto the watch and using its own built-in workout tracking, but if you’re someone who relies heavily on those third-party apps, it’s worth knowing upfront. For everyone else, the OHealth app on both Android and iOS covers the core experience well. If you’re pairing the OPPO Watch S with an OPPO or OnePlus phone running ColorOS 15 or OxygenOS 15, you also get bonus features like wrist-based control for TikTok and YouTube Shorts scrolling, plus a camera remote.

Verdict

The OPPO Watch S at RM799 is one of the best smartwatches you can buy at this price point. The design is slim and stylish, the display is brilliant, the health tracking sensor package rivals devices that cost significantly more, and the battery life is genuinely a differentiator.

Yes, the lack of WearOS means no third-party apps like Strava or Spotify natively on the watch. That matters to some people. But for the majority of users who want a daily wearable that looks great, monitors their health seriously, and lasts more than a week on a single charge, the OPPO Watch S ticks practically every box.

I own five smartwatches. The OPPO Watch S is the one that’s been on my wrist every day since I started using it. That’s my honest recommendation right there.

The OPPO Watch S is available at RM799. You can grab it from OPPO’s official store and major retailers in Malaysia.
