Samsung is one of the earliest tech giants that made the jump into the smartwatch business. The wearable device was introduced in Berlin during the Unpacked event. The Pebble smartwatch was also one of the earliest entrants in the smartwatch conversation and the upstart company behind the device received financial support from a successful crowdfunding campaign.
The Galaxy Gear is a more expensive model, available at $300 and the Pebble is less expensive at only $150. The Pebble is thinner and it has a smaller the 1.26-inch LCD (144 x 168) display. The Galaxy Gear comes with the more spacious 1.64-inch AMOLED (320 x 320) display with interface based on Android OS.
Internally, the Galaxy Gear has more similarity with standard smartphones with its 800MHz Exynos single-core processor, 1GB of RAM and 4GB of internal storage. The Pebble has the weaker ARM Cortex M3 processor and only 96kB of RAM. The proprietary Pebble OS platform is capable of pairing with Android 4.3+ and iOS 5+ devices. On the other hand, the Galaxy Gear only supports Galaxy Note 3 phablet initially, but Samsung will add more compatibility later.
