That may mean the Gear S will only be compatible with a handful of the firm's own devices, though this is yet to be confirmed.
The main talking point surrounding the Gear S is its curved, 2-inch Super AMOLED display, which allows the wearable to sit more snugly on the wrist.
Inside you'll find a 1GHz dual-core processor, 512MB of RAM, 4GB of storage, Wi-Fi, Bluetooth 4.1, heart rate monitor, GPS and 3G connectivity.
That 3G connection will allow you to continue to receive notifications and alerts when you're out of range of your smartphone - you can also make and receive calls on the Gear S.
The Samsung Gear S comes with IP67 water and dust resistance, and in terms of battery you're looking at a 300mAh power pack, which Samsung says is good for two days.
Considering the Gear S has a bigger screen you may need to charge this watch a little more regularly, the G Watch on the other hand has a larger 400mAh offering and a smaller display.
The Samsung Gear S release date is pegged for early October globally, with more specific details and pricing to follow.
