Taiwan-based Asus, which launched its first wearable called the Zenwatch (priced at £149) at IFA Berlin in September 2014, is now set to launch the Zenwatch 2.

The next iteration will be an advanced version of the original Zenwatch, according to rumours that have recently surfaced. According to Focus Taiwan, the second-gen Zenwatch will offer a battery life of up to seven days.

The comparatively long battery life is reportedly the result of a significantly simplified chipset and OS configuration.

"As a companion device, its central processing unit and operating system should be more simplified than the current version, so that I can use it for up to seven days on one charge, rather than for just two days," stated Jonney Shih, Chairman of Asustek, to Focus Taiwan. Shih did not reveal the exact technical specifications of the Zenwatch 2.

Nonetheless, rumours indicate that the Asus Zenwatch 2 will offer voice-calling using SIM-card, independent of a smartphone.

Asus' Zenwatch 2 is also being touted in media circles as a worthy competitor to the Samsung Gear S that features a standalone SIM card slot for voice-calls.

As of now, speculations are rife about the Asus Zenwatch 2 being launched officially during Q3 2015.
