Attached you will find a picture of the O-ring used in the Suunto DX dive computer. It has a round cross section, as a regular Oring, but it's not circular in shape. I can get them in Germany, but I wonder if anybody knows where to get it in the US. The DX exhibits a much better closure than the D6 and D4 for the rear case and it's light years ahead of the infamous closing system of the D9. The DX has six (6) Torx screws, which represent a significant improvement over the two (2) screw closing system of the D4 and D6.
