Both watches run Android Wear and, since Google doesn't let OEMs customize the wearable OS, their software is going to be almost identical. The only exceptions are add-on apps, like Motorola's always-on heart tracking app.
Size (main body)
The Moto 360 is about 10 percent taller and wider than the Huawei Watch. The Moto does leave a pretty wide impression on the wrist, so that smaller profile may not be such a terrible thing.
Neither watch is particularly thin, with the Huawei Watch only measuring about 2 percent thinner than the (somewhat beefy) Moto 360.
No weight measurements for the Huawei Watch just yet.
Build (main body)
Both watches have stainless steel bodies, and draw design inspiration from standard timekeeping watches.
Default band options
You can buy the Moto 360 with either a leather or steel band, and it looks like Huawei will be offering the same options.
You can swap both watches' bands for a standard one of your choice. For the Moto 360, that's a 22 mm band, and one of Huawei's promotional videos shows a brief mention of either 18 mm or 21 mm bands. We'll update when we confirm its compatibility.
Motorola and Huawei are offering their own versions of black, silver and gold color options.
Each watch has one (faux winder) button, at the 3 o'clock position for the Moto 360, and at the 2 o'clock point for the Huawei Watch.
It's tough to get an exact area for the Moto 360's not quite fully round screen (due to that cut-off point at the bottom), but our estimates have the Huawei Watch's screen giving you around 83 percent as much real estate.
The Huawei Watch gives you a 40 percent sharper screen (based on pixel density).
AMOLED looks like the way to go for smartwatches, as they can more easily run dimmed (nearly black) watch faces all day long, without draining ridiculous amounts of battery. Motorola stuck with an IPS panel for the 360 and – surprise, surprise – it has trouble getting through a day with its ambient (turns on whenever your wrist is within typical viewing angles) screen setting turned on.
Rather than glass, the Huawei Watch's display is hiding underneath a layer of sapphire. The Moto uses a more standard (but still quite strong) Gorilla Glass.
It's too early to say much about the Huawei Watch's battery life, but Moto 360 buyers should be prepared to leave the ambient setting turned off (i.e., black screen when you aren't actively using it) to safely get through one full day.
The Moto's battery does have one bright spot: its wireless charging seems like a perfect fit for a smartwatch. Just rest it on its included charging dock (and watch as it turns into a faux desk clock) to juice up during the night.
The Huawei Watch includes a charging cradle, and it doesn't look like it supports wireless charging.
Huawei hasn't said much about its Watch's water (and dust) resistance, but we'll update when we find out for sure.
Heart rate sensor
Both watches (like most multitouch smartwatches) have heart rate monitors. Motorola's periodically checks your pulse in the background throughout the day and can deliver (optional) daily summaries. We'll have to wait to see if Huawei has anything like that tied to its sensor.
The Huawei Watch uses an industry standard Snapdragon 400 processor, while Motorola (somewhat questionably) offloaded some obsolete Texas Instruments processors in the Moto 360. It's questionable, because that (along with its IPS panel) could be contributing to the Moto's not-so-amazing battery life.
This is another industry standard, as every Android Wear smartwatch so far carries 512 MB of RAM.
Right now storage isn't anything you need to worry about with Android Wear watches, as 4 GB should be more than you'll ever need.
Huawei is being tight-lipped about an exact release date, only saying that the Watch will launch sometime in 2015. The 360 launched last September.
Also no word on Huawei Watch pricing. The Moto 360 with leather band rings up for US$250, while the steel band version (pictured) costs $300. Of course you also have the option of buying the entry-level version and taking it to a jeweler to swap out your own (most likely less than $50) steel band.
