This watch belongs in the popular Frogman series. The DW-9900 was launched in 1999 and is the third Frogman model in the Frogman series. This DW-9900 is also considered as the left-hand model as the Frogman is on the left as compared to the DW-8200 or GW-200 series. Other difference between the DW-9900 and the rest of the Frogman is that this is smallest Frogman in the Series. Additionally the display on the DW-9900 is 2 tones with the upper display having the blue green background and the lower display having the standard green background. There are exceptions within the DW-9900 range; with one model having gold background on the upper display and four models not having 2 tones display.
This watch is blue in colour and falls under the Blue Sea series. There are 3 other models issued under the Blue Sea series; G-2000BS-2JF, DW-6900BS-2JF and G-100BS-2JF. This series was issued in July 2001 and the DW-9900BS was the last Frogman to be issued under the DW-9900 model.
As earlier stated, the watch is blue in colour, but it is not the jelly blue, more translucent then transparent. The wordings, ‘Frogman’ is in firecracker red, the ‘G-Shock’ and “Titanium’ is in black. As stated earlier, the display is 2 tones. The dial is black. With module 2016, the time is displayed in all modes except CDT and stopwatch. Other functions are as listed above.
The watch is fitted with a lightweight band made from resin and it is transulent blue in colour. The strap is also different from the rest of the Frogman strap as it is tapered rather then stepped. Markings on the strap are ‘Diver’s 200m’ and ‘Rust Resist’. The only other model with ‘Rust Resist’ on the strap would be the Gulfman. (I stand corrected on this) The strap is smooth on the outside except for the center section, which has a channel and is textured. The internal of the strap is textured and has the anti-slip ridges at the edge. Internal markings: 500 F1 16. The watch is comfortable on the arm either left or right hand. In fact the smaller size and with lightweight titanium, the watch is one of the more comfortable Frogman that I have.
The strap and buckle is of the 2-prong design. The buckle is made in Japan and is of the same design as the newer Frogman from the GW-200 series. The buckle is marked with the G-Shock logo. I cannot verify if the buckle on the DW-8200 and DW-6300 is of the same design as I only have the DW-8201WC Frogman and the buckles on this watch is the standard buckle found on many G-Shocks, unmarked but dual pronged.
The case back is typical Casio Frogman; Titanium, screw back and matte. The usual markings, warnings and Frog logo adorn the case back. The Frogman is serialized.
Overall, it is a nice watch.
