Samsung Electronics has unveiled small improvements to its computerized wristwatches in order to lure shoppers during the upcoming holiday season.

Samsung's Gear S can be easily used without a smartphone. It can be wrapped around the wrist rather than having a traditional flat rear surface.

Gear S has a curved super amoled display with 2-inch diagonal measurement and 360 x 480 resolution. The device also has in-built 3G modem that permit users to receive messages and notifications from calendar, social networks and apps.

The Gear S will allow the users to make and receive phone calls but it is not clear how it will operate since it does not have a phone number.

The smartwatch provides turn-by-turn walking directions through mapping data from Nokia's Here service. It also has a heart rate monitor, barometer, UV detection, compass, gyroscope, GPS sensors and an accelerometer.

It is powered by Samsung-owned Tizen OS, which is also present is Samsung Gear 2 and Gear Neo devices. The smartwatch will have 512 of RAM and 4 GB of internal storage.

Gear S has dual-core 1.0 GHz processor, and IP67 water and dust resistance along with 300mAh battery that can work for 2 days under normal conditions.
