Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Thanks to the weather-sealed body of the WG-3 GPS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the S6900.
LCD Screen Size and Features
Nikon S6900 and Pentax WG-3 GPS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon S6900 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Pentax WG-3 GPS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S6900.
