The two watch faces are both round, with 42 mm diameters. The LG Watch's 46-mm measurement accommodates for the crown that butts out a small amount from its right side.
Build (watch face)
The LG Watch Style watch face has a stainless steel casing and a Gorilla Glass 3 front. The back portion (which touches your skin) is plastic.
The Huawei Watch face is stainless steel, excepting the heart rate sensor on its back. Its sapphire display covering (the third hardest mineral on the planet) bests the still-capable Gorilla Glass.
You wouldn't necessarily be able to tell from a spec sheet, but the Huawei Watch's overall aesthetic is much more jewelry-like than the subtly tech-y LG Watch Style.
Each watch face is available in three metallic/neutral color variants, for matching to your wardrobe.
The LG Watch Style ships with a leather band, but the band is interchangeable. Water-resistant silicone bands are sold separately if you need a sportier option.
The Huawei Watch ships with either stainless steel or leather bands. If you purchase additional bands, you can also swap them out as you see fit.
While both watches have 42 mm casings, the Huawei Watch fits in a larger display, with narrower bezels.
Display resolution is neck-and-neck between the two. The LG Watch Style comes in at a slightly higher pixel density, but it's not enough to be significant.
The LG Watch Style has a P-OLED (plastic OLED) display. It's AMOLED for the Huawei Watch.
Always-on display option
Both watches have always-on display options, for access to time and notifications without having to "wake up" the watch.
The LG Watch Style has a rotating power button similar to the Digital Crown on the Apple Watch. This adds an additional physical method for scrolling through your watch's contents, so you don't have to rely on the touchscreen alone.
The two watches have identical IP67 water resistance ratings.
These watches rely on proximity to your smartphone and Wi-Fi network. Neither one can dial into your cellular data plan.
Unlike many other watches, these wearables don't contain a built-in GPS.
Heart rate sensor
The heart rate sensor (a common feature is smartwatches and fitness trackers) is conspicuously absent from the LG Watch Style.
Neither of these watches support mobile payments; they don't contain the requisite NFC technology.
Battery life is another too-close-to-call spec. The Huawei Watch's battery capacity is slightly larger, but a number of factors go into overall battery life.
LG Watch Style is one of the first to sport the Android Wear 2.0 operating system. The Huawei Watch still runs an earlier version of Android Wear, but it is in line to receive the 2.0 update in the "coming weeks".
The Huawei Watch is part of the first wave of smartwatches, released back in September of 2015. Note that Huawei has confirmed that an updated version of its watch – the Huawei Watch 2 – will be announced at the end of this month. On the other hand, the LG Watch is less than a month old.
The LG Watch Style's starting price is a relatively affordable US$249. The Huawei Watch had a $300 price tag when it was first released.
If you're eying the Huawei offering, we recommend hanging onto your money at least until its newer generation is announced. The Huawei Watch 2 may be more compelling, or it could drive down the asking price of its predecessor.
