Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax S1 is significantly lighter (67g ) than the Olympus TG-860 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the TG-860, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the S1.
LCD Screen Size and Features
Olympus TG-860's 3.00" LCD screen is slightly larger than Pentax S1's 2.7" screen.
In addition to the size advantage, Olympus TG-860 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Pentax S1 has a fixed type screen which provides less flexibility in shooting positions compared to TG-860.
