The HSV version is on the left, a basic MTG-930 on the right.From all first generation Tough Solar Waveceptor models I liked the MTG-930 most. I find the three eyes an attractive design, but the eyes are much smaller than on the DW-6900. The eyes of the MTG-930 do have a totally other function than those on the DW-6900. While the eyes of the DW-6900 simply count up and down the seconds. The big left eye shows roughly the time in minutes of the hour. The eye of the Frogman has a similar function.
