The DW-5900TS series has a unique feature that allows the information on the face to be seen through a florescent layer. When the EL backlight is turned on, this panel subtly glows, making it a stand out feature and a talking point. The series includes the DW-5900TS-1ER, which combines a black case and band with a fluorescent green dial. Functions include a 5 year battery life, world time and alarm modes, and 200M water resistancy.
