You demanded it, and we're getting it VERY SHORTLY! The GBDH1000 Heart Rate Monitor watch combines the latest in fitness technology, without the need for a bulky chest band! I'm really excited to share what this series has to offer, so without further ado, let's get to it!

GBDH1000-1A

First up, the GBDH1000-1A. This is a solid black watch, with a black band, bezel, and an extra-large digital screen. As you can see, the screen shows the time, your heart rate, distance walked/ran and your pace (which is how long a km would take at your current speed - but we'll talk about that later on).

GBDH1000-1A4

Next up is the GBDH1000-1A4. While it has a black band too, the bezel is transparent grey, with gold screws, and orange writing. The band itself, along with the buttons are peppered with orange and caramel colours.

GBDH1000-1A7

Then we've got the GBDH1000-1A7. While we're used to any model starting with 1 to be black, this watch shakes things up a bit. the bezel is black, but the band is white with a bit of lime green.

GBDH1000-4

The GBDH1000-4A is next on this list. It's almost fully red, apart from the dark blue bezel. One interesting thing about all of these watches (and the ones that'll follow), is the band kind of looks like a set of claws, clamping onto the bezel. Definitely makes for a unique look.

GBDH1000-7A9

The GBDH1000-7A9 is almost a carbon copy of the 1A7, with the only differences being the bezel is transparent grey. The green parts here are a bit more prominent, going onto the buttons themselves to match the motif.

GBDH1000-8

Finally, we have the GBDH1000-8. This one is a darkey shade of grey, making it less transparent. It's got red and black buttons, with red writing on the outside of the display. Now, one thing I should mention is, unlike the other watches I've reviewed, these ones ALL have a negative display. That's not a bad thing in this case, though. Well, now that we're done staring at these beauties, let's have a look at what they actually do.

This first part is self explanatory - they're heart rate monitor watches. To accurately measure your heart rate without any chest strap, they use an optical sensor. In layman's terms, they use light, to measure tissue change (when your heart rate is high, there's less light, and when it's low there's more). This was created by a company called FIRSTBEAT, which was made specifically to keep track of your running information.

Another feature that they have come up with is your pace. After running/walking for a bit, the watch uses the GPS to generate information on how long it'll take you to do a Kilometre at your current pace. I took it out for a test run, and it was accurate to the second, always taking your new speed into account when you go faster.

Now, if you're familiar with the GBA800 series, the GBD800, as well as the countless female step counter watches, you might think there's nothing that can surprise you, but Casio has outdone themselves. You can download your entire step history since you started using the watch. So you can see exactly how many steps you took every day, as well as create a fitness plan based on your past results.

This covers the exercise part of the features, but there are plenty of other features. The watch is rechargeable in two ways. Firstly it's solar powered, so all you have to do is have it in the sunlight and you won't lose power. Secondly, if you're anywhere near a computer (or your smart phone charger) you can plug the watch in, and it charges up.

The watch includes plenty of exploring features, such as a GPS, which ensures you don't get lost. It also has a digital compass, barometer, altimeter and thermometer. If you need to set an alarm, it also has a vibrating function if you want to keep it on silent.
