I think Fer is right, that it is the "gold" version, so the DW-5600C-9. In this case, the gold version means the accents on the display and bezel were yellow, instead of red/white (sometimes referred to as "silver").
The pics I saw online show silver screws, but in his pictures the border looks like a faded yellow on the top. It might be faded because it isn't in great shape. Or it is just a DW-5600C and, like Kung-Fusion said someone put gold buttons. But I am pretty sure there is no 5600C with a white line and gold buttons.I think someone put gold buttons on a silver series dw-5600c. If it was the real gold dw-5600c the border would be gold tone (it doesn't look like it is) and the screws would be gold, right?
The pic could be misrepresenting the true color of the crystal's graphic though...
