Suunto Core Multifunctional Watch

Suunto Core Multifunctional Watch

The Suunto Core Multifunctional Watch is one of the best altimeter watches on the market. It comes loaded with several functions that are essential for navigation. The watch is extremely durable and performs exceptionally well even in harsh weather conditions. The case is made of a resilient composite material. The bezel is aluminum. The display is made of mineral crystal and features a backlight. However, note that the backlight is rather dim and difficult to read unless you are in complete darkness. Here are the key features of the Suunto Core:

  • Altimeter/barometer, compass, and thermometer;
  • Automatic Alti/Baro mode to switch between altimeter and barometer functions;
  • Barometric altimeter is accurate to 29,500 feet and displays current elevation and ascent/descent;
  • Storm alarm;
  • Stopwatch timer, countdown timer, 1 daily alarm, sunrise/sunset data;
  • Depth meter for snorkeling up to 10 m;
  • User-replaceable battery with low battery indicator;
  • Battery life: 12 months;
  • Water resistance: 30 meters.

The Suunto Core Multifunctional Watch features one of the best altimeter/barometer functions of all the altimeter watches on the market. It measures long-term pressure trends and provides accurate data. The watch shows elevation in 3-foot intervals. There is also an altitude log.

This is a really handy feature because the watch can log your total ascent/decent and the number of runs for 7 days. The Core also has a graph that shows both altitude and pressure trends. The watch switches between altimeter and barometer automatically and provides you with information about the weather.

When the Suunto Core detects an incoming storm, it alerts you with the storm alarm. Not all altimeter watches have this safety feature.

The Suunto Core Multifunctional Watch also includes traditional watch functionality including a stopwatch timer, countdown timer, sunrise/sunset data, and daily alarm.

The watch is water resistant to 30 meters and this is not the best among the watches we reviewed. Water resistance to a 30-meter depth means this watch is not suitable for scuba diving. However, snorkelers can use this watch without problems and can use the waterproof buttons to obtain accurate depth readings up to 10 meters.

The battery of the Suunto Core is replaceable. The battery life is up to 12 months. There is a low battery indicator that informs you when the battery needs replacement.

All in all, the Suunto Core is one of the best altimeter watches on the market. Although this watch is one of the more expensive among watches without GPS, it performs exceptionally well and provides accurate data, justifying the price. Outdoor enthusiasts love the functionality and reliability of this watch.

Important Watch Features

Weather change is caused by variations in air pressure. An altimeter watch informs you of pressure changes in the barometer mode. You will be aware of incoming inclement weather and can prepare for any harsh weather conditions in advance. For a higher price, you can get an altimeter watch with a built-in GPS and other advanced features that track your activity.

There are literally hundreds of altimeter watches on the market and it’s easy to get confused. However, a good altimeter watch review can help you find the model best suited to your needs. You should know that if you are planning a long distance hike, you are likely to face changing and extreme weather, and not every watch can handle this. So it’s vital that your watch is durable and has scratch-resistant glass.

If you want an altimeter watch with GPS, you should pay attention to battery life as GPS can use up a lot of battery on long treks. The average battery life in GPS mode is about 24-50 hours. So, if your trek will last more than 1 or 2 days, you may need to carry spare batteries. To improve battery life in your altimeter watch, it is a good idea to set a longer GPS interval, but make note that this will result is less than perfect accuracy. In watch mode, however, the battery life is significantly longer and watch manufacturers are constantly trying to improve it further. Solar-powered watches are really the ideal solution for longer trips as you don’t have to recharge them as often or carry a replacement battery. Solar watches can last a few months without being recharged. In general, battery life is a crucial factor when choosing an altimeter watch.

Accuracy is also critical. A good altimeter watch is reliable and provides precise and accurate data.

So these are some of the important features you should consider when deciding on which altimeter watch is the best. But the question still remains – what is the best altimeter watch? We’ve tested several different watches to bring you a review of the best ones. Suunto, Casio, and Garmin are the leaders in this category. Their watches consistently have the highest scores among users.

The Bottom Line

An altimeter watch is an essential gadget for hiking, backpacking, mountaineering, skiing, or climbing. When you plan your trip outdoors, you need to prepare for the worst. You don’t want to get lost in the mountains or get caught in a storm. A good navigator watch with altimeter, barometer, and compass will keep you safe and make your trip all the more enjoyable. The altimeter and barometer functions are vital additions to a compass as they can help predict the weather.

We’ve reviewed the best watches with an altimeter that are both durable and perform well in all types of conditions including harsh weather. We’ve included some watches with only basic navigation features as well as others with fitness tracking functions. GPS watches are more functional, but they are also more expensive and have a lower battery life. So, consider whether you simply need an altimeter watch for navigation or a multifunctional watch with an altimeter, GPS, and fitness tracking. We hope you will find this review helpful in finding the best altimeter watch for you.
