Page promoting the DW-9400 "Thermometer" in the US brochure "Hard Body" of spring/summer 1998.
I got this image from Lee172. He wrote several articles a few years ago for 50 Gs. It is from a German catalog, probably from 1998 or 1999.
The DW-9500XS “Thermometer” was only released in Japan. In the US and Europe there was a DW-9400 Thermometer and a DW-9500US released, which was released for the US Open of Surfing in 1998. The DW-9400 model looks like the DW-9000 type models, but the module is probably the same as the DW-9500US. The DW-9500US has a 1683 module, which is similar to the 1681 module, but can change between ºC and ºF.

As the DW-9500XS models were specially designed for Surfing, it has a similar design as other G-lide models of the ‘90s, like the DW-003S, DW-9000S and DW-6900S. The strap is long enough to fit over a wet suit and additional holes allow air to flow between the arm and case, preventing nasty smells and irritations. There is even an additional hole in the strap adapter.
The DW-9550 case and bezel have a typical ‘90s G-Shock design. It looks much like the DW-9000 design, but at the front there is a metal ring instead of 4 metal pins.
