Suunto Core 2 Surfaces in Indonesian Certification, Hinting at Multi-Year Battery Life

Suunto's next outdoor watch keeps showing up in regulatory databases, and that usually means a launch is close. The Suunto Core 2, carrying the model number OW245, passed US FCC certification back in April, and now Gadgets & Wearables has spotted a matching Indonesian listing through the country's e-Sertifikasi system. The watch is classified as an "Outdoor Watch," manufactured in China, and the two filings agree on enough detail to confirm we are looking at the same product. Neither certification spells out a release date, but a growing stack of regional approvals is a reliable signal that a device is being prepped for shelves.

What's new

The headline change is power. The original Suunto Core runs on a CR2032 coin cell, the same flat lithium battery you find in car key fobs and motherboard clocks. The Core 2 moves up to a CR3032, a physically thicker cell rated at roughly 500 mAh. That is more than double the capacity of the CR2032, which typically holds somewhere around 220 mAh depending on the manufacturer.

Capacity alone does not tell the whole story, but it sets a useful baseline. The first Core already stretched a single CR2032 to about a year of use, because it spends most of its time driving a low-power segment display and a handful of sensors rather than a backlit touchscreen and a radio that is constantly chattering. Double the energy reserve, assuming similar draw, and a multi-year runtime between battery swaps becomes entirely plausible. For a watch you might take on a multi-week expedition, never thinking about charging is the entire point.

The FCC paperwork also confirmed water resistance to 100 meters, which clears the watch for swimming and casual diving rather than just rain and hand washing. Connectivity comes by way of Bluetooth Low Energy, the obvious choice for a device that needs to sip power while occasionally syncing with a phone.

How it compares

Set expectations accordingly: this is not a smartwatch in the Apple Watch or Garmin Fenix sense. The original Core, still sold for around $199, leans on barometric sensors rather than connected features. It packs an altimeter, a barometer, and a digital compass, pulls in weather data and storm warnings, includes a depth gauge for snorkeling, and shows sunrise and sunset times. What it deliberately leaves out is just as telling. There is no smartphone notification mirroring, no app ecosystem, no heart rate sensor, and no fitness tracking.

Nothing in the Core 2 filings suggests Suunto is changing that philosophy. The watch appears to stay in the same lane: a rugged altimeter-barometer-compass instrument with a display that runs for ages and survives a dunk. Against a modern multisport watch with optical heart rate, GPS, and a color screen, the Core 2 will look spartan on paper. Against a basic field watch, it offers genuinely useful environmental sensors without the daily charging tax. The CR3032 upgrade widens that gap in the one area where coin-cell watches already beat their rechargeable rivals decisively, which is the time between any kind of maintenance.

The move from CR2032 to CR3032 does carry a practical trade. The CR3032 is a less common cell than the ubiquitous CR2032, so replacements may cost a little more and be slightly harder to grab off a convenience store shelf. For a watch built to disappear into the background for years at a time, that is a reasonable price for the extra headroom.

Who it's for

The Core 2 is aimed at hikers, climbers, snorkelers, and anyone who wants altitude, pressure, and heading data on their wrist without committing to the charging routine of a connected sports watch. If you track structured workouts, monitor heart rate zones, or want notifications buzzing on your wrist, this is the wrong watch and was never trying to be the right one. If you want an instrument that tells you the weather is turning, how high you have climbed, and which way is north, and you want it to keep doing that through an entire season without a cable, the Core 2 looks like a sensible refinement of a formula Suunto already had working. Pricing and an exact launch window remain unannounced, but the steady drip of certifications suggests we will not be waiting much longer.
