5. Water resistant
The Sony Smartwatch 3, for example, is the most durable among Android Wear watches with an IP68 rating. That means it can be taken 1.5m deep for 30 minutes, but not deeper or longer.
While the official Pebble Time waterproof specs aren't known just yet, the first Pebble and Pebble Steel had a 5ATM rating, which makes it good for 50 meters (165 feet).
Pebble previously told me people have used its smartwatch while diving, though without a working Bluetooth connection for notification while under the seat. Pebble cutely suggests not making calls while underwater.
There are a lot of fun-looking, colorful animations for making calls, composing messages and receiving new notifications. Everything's laid out logically with a bit of pep.
7. Color e-paper display
Pebble Time skips out on the super-rich OLED displays popularly used LG and Samsung in favor of an always-on e-paper display, and this time it's in color.
Yes, it's color palette is limited to 64 colors, but it appears to be easier to see than before and that's really important when delivering a smartwatch that's worn all day long.
Sunlight gets in the way of OLED watches and wearing sunglasses - which you naturally do when it's sunny out - makes it even more complicated.
More from Barcelona next week
It'll be interesting to see how Pebble plans to overcome the limitations set by Apple. iOS voice replies are limited to Gmail notifications, though Pebble says that it's working to enable voice replies for more apps.
The good news is that voice replies work with major Android apps, including SMS, Hangouts, Gmail, Facebook Messenger, WhatsApp and hundreds more, according to the company.
TechRadar will be at MWC 2015 next week testing out the new color e-paper screen of the Pebble Time and all of its features in a hands on. Stand by for more from Barcelona, Spain.
