The
X6 has a clinometer and accumulative vertical and baromtetric data that can be downloaded to a PC via the serial port interaface. I believe the
Observer is
Suunto's best looking Wristop. The
X6 dot matrix display is actually a higher resolution LCD than all previous
Suunto models. The PC interface for the
X6 & the soon to be released
X6HR is pretty amazing. Bottom line: Do you want form (
Observer) or function (
X6 or
X6HR)? I understand it's a tough choice to make. I personally believe you can't go wrong with either model. FYI, they both are comparably sized which is about 30% smaller than all previous
Suunto Wristop models.
