Things to Remember Before Buying a Mountaineering Watch

Are you excited to go for your mountaineering adventure with a new watch on your wrist? We have a little bit of advice for you before you buy a watch. Apart from the 10 watches we have listed above, there are hundreds of different brands in the market ready to be adopted by the new owners.

However, there are a few factors you need to consider before making a decision. Some watches have amazing features than the others but you may not need all of those functions. Or maybe the price of the features you like is lesser for another brand with the same features.

Things to Consider Before Buying a Mountaineering Watch

Always know the features you want in your mountaineering watch before your expedition. Some of the major features that you must have are Altimeter, Barometer and Compass. These watches have the function of automatically updating the data in your watch memory for future use.


Altimeters measure air pressure so that you know the height you are in and can calculate the air density for you to do activities like camping in different locations.


Barometer assists you by measuring atmospheric pressure, which quickly helps you to be alert of any incoming storms. For example, you will know it will rain if the pressure drops.


Compass is very critical in mountaineering. The mountaineering watches offer 2D and 3D compasses. Make sure what you need before choosing your mountaineering watch.


Since mountaineering is mostly carried out in different time zone than you live, it is recommended that your watch has multiple time zones. It is easy for traveling, flipping between different time zones and keeps you away from fully resetting every time you travel.


Another major factor to consider is GPS which helps to track your location, the distance you have walked and the distance you need to cover before mountaineering.


Thermometer helps to know the temperature of the location and predict the weather in advance. Apart from that, don’t you want to brag to your friends how hot or cold the place you visited was?


Almost all mountaineering watches are waterproof. The only trick question here is – how deep can this watch dive before failing to resist water? Most will answer – 100 meters. Few mountaineering watches can dive deeper. Again the question is – what is your preference?


You will need a durable watch while mountaineering. Here, durability not only means a watch that has a long lifespan, but it should be able to resist shock, abrasion, scratches, water, and extreme temperatures.

Battery life is very important in mountaineering watches. Check how long the battery lasts after each charge.


Make sure that your watch is not too heavy. No one wants to be distracted by an uncomfortable watch while mountaineering. Check if the functions available are easy to operate. Look for the materials used in the band.

In Conclusion

Before buying any mountaineering watch, make sure you will be using most of the features of the watch, if not all. You need to figure out what you need and what you will not.

Choose something with advanced technology so that you do not have to buy a new watch again when you go for mountaineering next year!

Cheers to your adventure!
