I've been a smartwatch guy for many years.
I've worn a lot of them. Many shapes and sizes. Different brands. Various operating systems.
Some were basic activity trackers. Some have so many features it's more like wearing a flagship phone on your wrist.
So yes, I'm a fan.
And yet there are still many people out there who aren't into smartwatches at all.
These people have deprived themselves of all the fabulous features today's smartwatches have to offer; activity tracking, health monitoring, notifications on hand...and why?
Perhaps because most smartwatches are huge and nerdy-looking?
Maybe because so many smartwatches can't even get through a full day and night without having to be charged?
Okay. There are arguments. But OPPO makes some pretty convincing counter-arguments.
From the second I put OPPO Watch S on, I thought, "Yeah, this is a pretty nice watch." Note; I didn't say, "SMARTwatch" - just "Watch."
At just 8.9mm thick and weighing in at only 35grams (minus the strap) it's possibly the most unobtrusive smartwatch I've ever worn. Because it's so light and thin, it's one of those watches that's so comfortable, you forget you're wearing it. Even in bed at night.
This is a plus, because OPPO does a creditable job of sleep-tracking - but there's not much point if the device doing the tracking is keeping you awake because it feels too big and clunky.
There's also not much point if the device doing the tracking is on the charger on your bedside table. Not an issue with the Watch S; its battery life is pretty stellar. I'm getting four or five days on a single charge effortlessly, without resorting to any power-saving measures or opting for a less power-hungry, non-animated watch face.
It also charges very quickly on its proprietary magnetic wireless cradle - so I tend to just plonk it on there for a few minutes every day for a speedy top-up, thereby ensuring I never really get much below 80%.
I happen to think it's a pretty styley-looking bit of wrist-wear too. My review device is the Silver Gleam option, which features a shiny stainless steel casing and an eye-catching yellow/green/blue woven nylon strap. Unlike other fabric bands I've worn in the past, this water-repellant strap dries off very quickly after showering or swimming and I don't end up with a weird wet patch on my sleeve. Nobody likes a wet patch.
The woven strap is also extremely comfortable, adding to the overall pleasurability rating of the Watch S wearable experience.
There's a Phantom Black option too - and while that one has a more conservative black fluororubber strap paired with its black casing, that strap is curved for extra comfort.
Don't be afraid to get it wet, by the way. The Watch S carries a 5 ATM / IP68 water resistance rating, so you're all good there.
In the meantime, there a few limitations to this watch that stop it competing head-to-head with some of the other premium flagship watches, including OPPO's own Watch X2.
Firstly, the operating system. It runs ColorOS Watch 7.1 - which looks and feels very familiar to anyone who's used a WearOS device before but unlike WearOS, there's no ability to use Google apps here; so no Google Maps or Google Wallet.
This is a bit of a dealbreaker for me personally, because one of my favourite flexes in life is to pay for things using my watch to tap and go. Oddly, the Watch S does have NFC capability - you can add non-confidential access cards, for example. This is pretty fun - although it's hard to know which systems it'll be compatible with and which it won't. I can unlock my front door with it but it doesn't work on the card-readers at work. I guess those ones are too confidential?
However, there are some things the Watch S can do that even smartwatches five times the price can't.
For example, the large 1.46-inch AMOLED display gets incredibly bright - up to 3,000nits in fact. That means you can read it easily, even on the sunniest days, even wearing shades.
I've already mentioned the crazy-good battery life but how about the fact you can pair it to two different phones simultaneously? Why would you want to do that? - unless you're a gadget-addicted tech reviewer like me, obviously - Anyone who has a work phone as well as a personal one can answer that question right away. Get notifications from both handsets on a single watch.
As you would expect, the Watch S does an admirable job when it comes to exercise tracking, thanks in no small part to its dual-band GPS. I've found this to be very accurate and what's more, it locks on within seconds of starting your workout.
The Watch S can be set to auto-detect workouts like running, cycling, swimming and walking but perhaps more importantly, it can also auto-pause during a workout - like when you're waiting at the traffic lights, for example - then resuming once you're on your way again.
My only criticism here is the lack of customisation on the workout display - when doing an Outdoor Walk I'd prefer to have a live reading of my current pace and perhaps my cadence. Instead, I get my step total and calories burnt - along with duration, distance and heart-rate of course. Unfortunately, you can't play around with these metrics like you can on some other devices. Yet your pace IS shown when you do an Outdoor Run. Odd.
On the bright-side, you can pair the Watch S with other Bluetooth-capable exercise machines like treadmills and stationary bikes, so they'll display metrics like heart-rate and workout zones.
What's more, once your workout syncs back with the O-Health app on your phone, you can then dig into all the metrics you could possibly desire, and then some.
This is exactly what the Watch S does itself when you get it to run its 60s Wellness Overview - this holistic health check requires you to touch your finger to the electrode sensor on the side of the casing while ten different readings are collated, including an ECG, sleep tracking, blood oxygen levels and more.
If you're overtired and stressed out, you might be told to slow down and recharge.
On the other hand, if you managed to delete all those unimportant emails and fit in an afternoon app, you'll probably get some words of encouragement and a smiley face instead.
While you can't add an eSIM to use the Watch S independently of your phone, you can take Bluetooth calls on it and you'll receive notifications from any app you've got installed on your paired device. In saying that, this is a one-way stream - you can't respond to those notifications, even if they're texts, emails or direct messages - you can only read them.
So yes, there are a few limitations - but not many. Meanwhile, what the Watch S does, it does expertly. the screen is bright and responsive, the battery life is nuts and being able to pair with two phones at once will be a godsend for a lot of you. Oh, and did I mention it works with both iOS and Android handsets? What a great little watch. And I do mean little.
