The flat section, commonly known as the "flat tire," prevented the first Moto 360 from having a completely round display. It was deemed necessary to contain the smartwatch's components and keep the Moto 360's extremely thin bezels.
Other smartwatches like the LG Watch Urbane, Huawei Watch, and Samsung's upcoming Gear S2 all have fully round screens, but their bezels are noticeably thicker than the Moto 360's.
To some commenters from tech sites like Gizmodo, the compromise of thinner bezels but cut-out screen isn't worth it. "The Flat Tire is kind of dealbreaker for me," one person wrote.
Others are totally willing to make the compromise: "I don't mind the flat tire after a few days of use, you don't even notice it. I like the super thin bezel, and if that is what it takes to get that super thin bezel, then I am OK with it," another said

The button (known as the "crown" in watch jargon) has been moved from the 3 o'clock position to the 2 o'clock position. It also looks like Motorola added some lugs, the parts that connect the straps to the watch body.
Apart from that, little else is known about Morolola's next smartwatches, but many are expecting Motorola to make an announcement at the IFA event in Berlin in September.
