Like any G-Shock but with an added barometer, thermometer and altimeter. Cheapest I've found elsewhere is AU$123 domestically or ~AU$110 from overseas.

Perfect for the person that can’t get enough technology, this watch will keep you looking great, while keeping you punctual, provided you don’t lose track of time fiddling with this watch’s nifty alti-thermo. In addition to this cool feature, this timepiece features an alarm, timer, light, and water resistance to 200 meters. Plus with its 51mm black plastic case and black plastic band, this watch proves to be more than just an ordinary sport watch.

  Additional 10% off with coupons don't seem to work but there's links through savings.com which supposedly give you free shipping. I already bought so can't confirm.

  That is only about $12 cheaper than buying it here and you miss out on local warranty…

    I could be wrong, but I thought that Casio watches have an international warranty.

      Local warranty isn't just Casio warranty but the statuatory warranty with the store as well. With a brick and mortar store they could exchange it on the spot or fix it straightaway if its a quick fix. Statuatory warranty could be longer than the warranty Casio provides too.

  Lenneth where abouts locally are you talking about?

  Any know how accurate the twin sensors are?
  I have a single sensor casio and the readings for the temp when wearing it are always 10-15 degrees off.

    temp sensor won't be accurate whilst you wear it, and take a good 15 min to get to room temp once you take it off. Otherwise pretty accurate if you want to keep an eye on a room temp for kids etc.

    No thermometer can be accurate if it's being influenced by your radiant body heat obviously. You can actually calibrate the thermometer though to be offset by as many degrees as you need so that way you can get the air temperature while it's still on your wrist (the problem is your body temperature isn't a true constant and can vary somewhat, so you would have to continually recalibrate the thermo; if you want to be sure it needs to be taken off your wrist and away from direct sunlight as well).

    I own a few Casios with ABC sensors and thermometers (a Protek PAG-240, a Mudman GW-9300, G-Shock GA-100 and a few others) and generally they are as good as the majority of consumers need them to be.

    Unless you're planning on doing chemistry or flying planes with them, which no one of a sane mind would be, if you just want to know what the ambient temp is to within an accuracy of +/- 3C, it's as good or better than weather forecasts (and I compare my watches to weather forecasts quite frequently as well as other dedicated thermometers).

    As for the altimeter, all altimeter watches basically convert barometric pressure into altitude (via a formula much like this: http://www.engineeringtoolbox.com/air-altitude-pressure-d_46…), hence why they all measure barometric pressure too; which is a very rough calculation and is basically only good for very large changes in elevation (like literally climbing a mountain), then you could get a rough sense of the height gradient you've scaled and what kind of ascent/descent you've got left.

    My altimeter watches will sometimes tell me my house is 100 metres ASL or 20 metres ASL; it's not really useful. As Casio explains, for really accurate barometric readings you need a constant temperature, and atmospheric/weather conditions can also skew your readings.

    Though apparently pilots have used Casio ABC watches as rough guides and they were fairly useful (they can go as high as 10,000m).

    Not sure if it's possible with this G-Shock but with a Pathfinder/Protek watch, you can measure altitude via a second method by specifying a known reference altitude (the height of a nearby mountain/topograhpic maps) which the watch will use to compare it's reading to. It's more accurate that way but you need solid data to input which can be hard in an urban environment.

    Hi , You'll have to ask Chroma. I was just following his claim, sorry.

  A word on the negative/inverted LCD displays though; they look cool but have limited viewing angles and reduced contrast.

  Not sure how good this one is as it varies quite a lot from model to model depending on the LCD dyes used; the more recent negative LCD Casios are much easier to read than models from years gone by, but it's still a pain having to turn the backlight on whenever you're not underneath direct light sources.

  Hi Choroma,

  Where about can you get locally for $123?
