The S68 was a "premium-class" phone made of brushed aluminium and a black soft-touch coating. It was a mere 1.3cm thick.
BenQ-Siemens positioned the S68 as being simple to use and not "overloaded with a huge variety of unnecessary capabilities" and "superfluous gadgets".
This meant that it lacked a camera, memory card slot and video playback capabilities. However, it did have a colour screen and a built-in voice recorder.
BenQ-Siemens stated that it was targeting business users with the S68 and reflecting this it was possible to synchronise it with Microsoft Outlook or Lotus Notes using Bluetooth or a USB cable.
The Mobile Phone Museum collection includes the main variant of the phone and also a T-Mobile-branded version.
