Built for off-grid exploration
Suunto Core 2 combines altimeter, barometer and compass functionality with a durable design built for life outdoors. From hikes to off-grid adventures, it helps you track elevation, stay aware of changing weather and keep your bearings.
Stay ahead of changing conditions
Core 2 combines altitude and barometric data to help you read the outdoors as conditions shift. Track your ascent, monitor pressure trends and get storm alerts when the weather starts to turn.
Keep your bearings
When landmarks fade or the route becomes unclear, Core 2 helps you stay oriented with a precise digital compass, bearing lock and magnetic declination. Reliable direction when you need to keep moving forward.
Built for extended adventures
When you’re far from charging cables, power outlets and everyday conveniences, dependable battery performance matters. Suunto Core 2 uses a replaceable battery and low battery alert to help you stay prepared, with up to 15 months of battery life in basic time mode.
Designed for visibility and durability
Core 2 is designed for outdoor use where readability and durability matter. The high-visibility display stays clear in daylight, while red and green backlight options support low-light use. MIL-STD-810 tested durability helps it handle rough use on the trail, at camp and in the field.
Plan your time in the wild
In the outdoors, timing is just as important as direction and distance. Suunto Core 2 provides essential tools for planning activities around daylight conditions, managing time across journeys, and staying aware of natural cycles.

Is Core 2 a smartwatch?
No, and that's the point. Core 2 is a classic ABC outdoor watch, built around an altimeter, barometer, and compass rather than apps, GPS, or a touchscreen. It focuses on the essentials that keep you oriented and safe outdoors, with the long battery life and durability a smartwatch can't match.
What are the main features of Core 2?
Core 2 combines an altimeter, barometer, and offline compass for navigation and weather awareness, plus a storm alarm, sunrise and sunset times, and moon phase. It's built to military durability standards, rated to 10 ATM water resistance, runs up to 15 months on a replaceable battery, and has a high-contrast LED dot-matrix display with a switchable red and green backlight.
What is the difference between Suunto Core and Core 2?
Core 2 keeps the tool-watch DNA of the original Core and upgrades nearly everything around it: a switchable red and green backlight, stronger 10 ATM water resistance, a higher-contrast display, and larger buttons with better feedback. It also adds Bluetooth for time sync and updates, moon phases, and a refreshed, more modern design.
Can it be used offline?
Yes. Core 2 is designed to work completely off-grid. The altimeter, barometer, and compass all run without GPS, a phone, or a signal, so you stay oriented and informed even where there's no connectivity at all.
Can it be used in extreme environments?
Yes. Core 2 is tested to durability standards and built to handle heat, cold, moisture, shock, and rough handling. With 10 ATM water resistance and a long-life replaceable battery, it's made for demanding outdoor conditions.
How is altitude measured?
Core 2 measures altitude with its barometric sensor, reading changes in air pressure to track your current elevation and your total ascent and descent. Because it's barometric rather than GPS-based, it responds quickly and works anywhere. Calibrate it at a known elevation for best accuracy.
Why is altitude inaccurate sometimes?
Barometric altitude depends on air pressure, which also changes with the weather. When a weather system moves in and pressure shifts, your altitude reading can drift even if you haven't moved. Recalibrating at a known elevation resets it and keeps readings accurate.
What is barometric pressure used for?
Core 2 uses barometric pressure two ways: to calculate your altitude, and to track weather trends. By watching how pressure rises or falls over time, you can anticipate changing conditions, and a sharp drop triggers the storm alarm for early warning.
How does storm alert work?
Core 2 continuously monitors barometric pressure, and when it detects a rapid drop that signals worsening weather, it sounds a storm alarm. That early heads-up gives you time to seek shelter or adjust your plans before conditions turn.
How accurate is the compass?
Core 2 has a precise digital compass with bearing lock to hold a heading, plus magnetic declination adjustment so you can align magnetic north with true north for your location. It works entirely offline. For best accuracy, calibrate it regularly and keep it away from magnetic interference.
Does it support dual time zones?
Yes. Core 2 lets you track a second time zone alongside your local time, which is handy for travel or staying in sync with people back home.
How does sunrise/sunset work?
Core 2 calculates sunrise and sunset times based on the date and your location, so you can plan daylight around hikes, camp setup, or the trip back before dark. It also shows the moon phase to help you plan night activities.
Does the Suunto Core 2 have an alarm?
Yes. Core 2 includes a daily alarm, so you can wake for an early start or set reminders on the trail.
Does Suunto Core 2 have a stopwatch?
Yes. Core 2 has a built-in stopwatch for timing activities, intervals, or anything else you need to track.
Does it have a backlight?
Yes, and it's switchable. Core 2 offers a green backlight for high contrast in haze and low light and a red backlight that protects your night vision, so you can read the display clearly whatever the conditions.
What battery does Core 2 use?
It uses a CR3032 coin cell battery, which is user-replaceable.
How long does the battery last?
Battery life varies by usage, but typically can last up to 15 months with standard use.
Is battery replacement difficult?
Users can replace it themselves, but it is recommended to use official replacement parts.
Can it connect to a phone?
Yes, it supports synchronization and settings management via the Suunto app.
What if syncing fails?
Check if Bluetooth is enabled, ensure the device is within range, or try re-pairing.
Can it be used offline?
Yes, core functions work independently without a phone connection.
Does Core 2 have GPS?
No. Core 2 is an ABC watch, not a GPS watch. Instead of satellite tracking, it uses an altimeter, barometer, and compass to help you navigate and read conditions. Leaving out GPS is exactly what gives it such long battery life and true off-grid reliability.
Does Core 2 have Bluetooth?
Yes. Core 2 connects to the Suunto app over Bluetooth to sync the time, sunrise and sunset data, and your step count, and to receive over-the-air updates. Day to day it works fully on its own, so the connection is there when you want it, not something you rely on outdoors.
