The Samsung Gear S3 has leaked in the lead up to its unveil as its codename, Solis, has been outed along with model numbers and OS details.

According to sources of Sam Mobile the next Samsung watch is being developed under the codename Solis, meaning Sun in Spanish. Since the last Gear S2 used the codename Orbis, also on that round theme, this seems like its successor.

The source says that the new Solaris watch will come running the Tizen operating system, as opposed to Android. This will come with an updated interface that will likely take advantage of the same rotating bezel control system the Gear S2 offers.

No other specs are revealed aside from the model numbers: SM-R760, SM-R765, SM-R770, SM-R765V, and SM-R765S. It's stipulated that the 1.2-inch display of the Gear S2 may get a size upgrade to help make touch interactions, where the bezel control isn't used, a little more easy.

Another area we'd like to see improvement in is battery life. For many a smartwatch is yet another device to charge and extending life for less plug-in moments is always a good move.

Luxury jewellers de Grisogono has revealed that it is working with Samsung to co-create a high-end version of the Gear S3. This is likely an attempt to take some of Apple's market share in the luxury wearables sector.

Expect to hear more on the Samsung Gear S3 as leaks increase ahead of an expected reveal at Samsung Unpacked on 2 August when the Galaxy Note 7 is expected to appear. Failing that an IFA appearance in early September is likely.
