Back to the heavy duty watches again today.
My Friday watch is another of Casio's G-Shock watches. This model is the DW-9000 and was released in around 1997/8. There were many colours released (this one is a pale green jelly version), and the watch could come with a resin or fabric/velcro strap. One online shop also quotes this as being part of the G-Shock Glide series.
It has the distinctive G-Shock look, with a large plastic shock-resistant cover on the case and well protected buttons, as well as the 20bar water resistance. The LCD display is split into four sections, two with numbers, and two with blocks. The number lines are on the top and bottom and show day and date (top), and time (6 digits, bottom). The other sections fill and empty with seconds, with one covering 10 second blocks, and the other being individual seconds.
It uses a Casio 1659 module which takes a CR1616 battery. The module is a Casio Illuminator model with the electro luminescent back light activated by the big G button on the front. Other modes are alarm, timer, and stopwatch. The calendar covers up to 2039, with month lengths, leap years etc., and has a summer time option for quick time updates.
The G-Shock watches are known for their toughness, and another blog (Gear Geak - link) has done a torture test on this particular model. They sat it underwater, froze it, boiled it, sat it in a dryer, ran it over with a car, and dropped it - and the watch still ran!
