The Suunto Core has been a go-to instrument watch for New Zealand hikers, hunters and anglers for years — no GPS, no fuss, just a reliable compass, altimeter and barometer on your wrist. Suunto Core 2 has already launched overseas, and it's landing in NZ later this year — keeping that same no-nonsense formula while upgrading the areas Core owners have been asking about most: battery life, water resistance, display, and connectivity. Suunto is calling it "Same Soul. Better Everything," and after going through the specs side by side, that's a fair summary.
If you're deciding whether to pick up the original Core or wait for the Core 2 — or whether it's worth upgrading from your current Core — here's how the two actually compare.
Battery life: built to last longer
The original Suunto Core runs on a CR2032 battery for around 12 months. Suunto Core 2 moves to a CR3032 cell and stretches that out to up to 15 months — a meaningful difference if you're relying on this watch for multi-day trips in the backcountry where a battery swap isn't exactly convenient. Both batteries are user-replaceable, so there's no trip to a service centre either way.
Tougher build, ready for more water
This is the standout upgrade. Suunto Core is rated to 30 m water resistance — fine for everyday wear and light water exposure, but not something you'd want to rely on for anything beyond that. Suunto Core 2 jumps to 100 m water resistance, putting it in a completely different category for swimming, snorkelling and general water-based activity.
The build has been refined too: Core 2 swaps the original's aluminium bezel for stainless steel, and moves from an elastomer strap to silicone. It's slightly heavier as a result (74 g vs 64 g), but the trade-off is a noticeably more rugged, premium feel on the wrist. Suunto has also put Core 2 through MIL-STD-810H military durability testing, and upgraded the display itself — a 40% brighter LED dot-matrix screen under Gorilla Glass, which makes a real difference for reading your compass or altitude in bright sun or low light.
New: Bluetooth connectivity
This is the biggest structural change between the two watches. The original Suunto Core has no connectivity at all — what's on the watch is all you get. Core 2 adds Bluetooth with app pairing and firmware updates, so you can keep the watch current over time without needing to buy a new one for future improvements. It's still not a smartwatch — no notifications, no GPS — but it closes the gap that's probably put off buyers who wanted at least some connectivity from a Suunto.
New: Hunting Mode
Suunto Core 2 introduces a dedicated hunting-focused feature the original doesn't have: a red backlight mode compatible with night vision goggles, available 24/7. For hunters who need to check the time or compass without blowing out their night vision, this is a genuinely new capability rather than just a refinement of an existing one.
Compass, altimeter and weather: the core experience, sharpened
The essentials that make a Suunto instrument watch what it is haven't changed — Core 2 keeps the same 5° compass accuracy with 1° resolution, bearing lock and north indicator that Core owners already trust. The altimeter range shifts slightly, extending up to 10,000 m (from 9,000 m), and the weather suite gains a moon phase calendar alongside the storm alarm, sea-level pressure tracking and sunrise/sunset times carried over from the original.
Core 2 also adds basic step counting — a small nod to everyday activity tracking that the original Core never offered, without turning this into a smartwatch.
Should you upgrade?
If you already own a Suunto Core and it's doing the job, there's no urgent need to replace it — the core navigation and weather tools are largely the same watch under the hood. But if water resistance has ever been a limiting factor, if you want longer stretches between battery changes, or Bluetooth firmware updates and the hunting-specific backlight matter to how you use your watch, Suunto Core 2 is a clear step up.
For anyone buying new, Core 2 is the easy recommendation: better battery life, far better water resistance, a brighter display, Bluetooth connectivity, and a tougher build — at $499 NZD, the same price the original Core launched at.
