Could you at least read the reviews before you make grand statements?
The Samsung S2 3G has horrible battery life when the cell radio is used.
Nice job of showing a picture of the none 3G watch which is much thinner also.

"It's more expensive, requires a connected data plan to pair with, and runs out of battery life quickly on cellular. It's bulkier, too."
"But it's also really thick. It felt OK on my wrist, but anyone who prefers smaller watches or bands might object."
"I didn't mention battery life, but it's not great. It has about three or fours of active use, or a day (or less) of regular standby use with cellular turned on. It ran out of juice on my wrist by early evening, most days, and I wasn't using it much. It charges via a wireless cradle that's included."
THREE OR FOURS HOURS OF ACTIVE USE. LESS THAN ONE DAY OF USE WITH CELLULAR TURNED ON STANDBY.
PLUS THE WATCH IS ABOUT 30% THICKER THAN THE LARGEST APPLE WATCH, WITH A SMALLER USABLE SCREEN SIZE.
Like I said the tech isn't ready for a 3G smartwatch with equal battery life as the current AppleWatch in the same size case. Sure you can fit it in a much bigger case or sacrifice full day battery life. But most people want full day battery life and don't want to wear a massively thick watch on their wrist.
