So, onto the watch itself, the model reviewed is the GDF-100-1AER. First impressions are good. [PRBREAK][/PRBREAK]The watch comes well packed as expected with a card outer and a metal 'nut box' (unlike the more normal plastic ones). The watch is large, approx 47mm diameter excluding buttons (for comparison a GW-9200 Riseman is 44mm) and well made as one has come to expect of Casio G-shock line up. The black resin is a little more matt than normal, the band is double slotted and the metal clasp has a slightly brushed finished. The display is clear and crisp, the digits being slightly larger than Casio's normal offering.
The 'headline' features of this watch are as follows
- Altimeter
- Barometer
- Thermometer
- EL
- World Time
- 24h stopwatch
- 24h countdown timer
- Alarm

The remaining features are fairly run of the mill. World time. Alarm and hourly chime. 24 hour stopwatch and 24 hour countdown timer - two features which are in demand by some. The current time is also visible on these screens.
On the wrist the watch wears like any other large G-Shock. The case sat well across the top of my 7 ½” wrist and the strap was well countered away from the watch giving the GDF-100 a snug and comfortable fit. It’s a big watch of course but feels fine on; it lacks the heft and height of something like a GW-200 Frogman. Visually it’s an imposing piece and is instantly recognisable as a G-Shock thanks to its looks and of course the red G EL button. This size may not be too everyone’s taste, it does almost seem to be big for the sake of being big. The LCD display is a slight departure from previous Casio offerings, will have to spend a little time with this to draw an opinion. The sensor protrusion on the left of the case may not be to everyone’s liking, further it may cause issue for those who wear their watches on their right. A size comparison of the GDF-100 with the GW-M5600 and GW-9200 can be seen in the thumbnails below.
