Sunnto Core Wrist Top Computer Watch with Altimeter, Barometer, Compass and Depth Measurement:
This is probably one of best watches in the ABC category. It has a very easy to read display with white background and black letters OR black background and silver and white alpha-numeric letters. The Altimeter, Barometer and Compass functionality is incredibly accurate and beats many watches in it’s class. Some of the users have actually compared this watch with the actual altimeter, barometer and compass instruments and the watch came on par. It also has a storm alarm which reacts to the air pressure changes. Once you set your course, compass actually indicates which direction to go to with an arrow indicator as well as the words ‘Left’ and ‘Right’. Only thing that’s negative about this watch is Alarm, which is not as strong as some people would like. I would recommend this watch for outdoor lovers and it comes with mostly everything that outdoor person would need during hiking, biking or camping.
Casio PAW1500T-7V Pathfinder Multi-Band Solar Atomic Ultimate Watch:
This watch is also a great watch for the price. It’s compass is very consistent, altimeter is very accurate and is within 5 meters, barometer 
functionality is also very consistent and accurate and trend graph feature is found to be very useful by majority of the users. Since the thermometer is very sensitive, it might give you a wrong reading if you are wearing it due to the body temperature, but if you take it off you can see that the thermometer is very snappy and accurate as well. It’s very stylish for a digital watch with so many functionalities, it’s dependable and very comfortable to wear. One thing we suggest is that to read the manual very carefully to fully make the use of this great sports and outdoors watch.
Sunnto Vector Wrist Top Computer Watch with Altimeter, Barometer, Compass and Thermometer: 
If you are looking to buy a cheaper watch in ABC category than this might be the watch you are looking for. It is Sunnto’s one of the older models but does the trick and does it well. It has the Compass , Altimeter, Compass and functionalities which are pretty consistent and accurate. Just like most of the other watches, Thermometer functionality is not that great when you are wearing it due the body temperate and you have to take it off for at least 10 minutes or so to get the actual reading of the temperate. I would suggest this watch for people that don’t want to spend a lot of money in the beginning.
