Coros, the sports watch brand known for durable gear aimed at runners and adventurers, is stirring up excitement with fresh leaks about its upcoming Apex 4 smartwatch. Detailed images and specs shared online suggest this new model will offer a massive 30 times boost in speed compared to earlier versions, a 62% jump in battery life, and handy additions like built-in speakers and microphones for calls.
The Apex 4 could launch as early as October 15, building on the success of the Apex 2, which starts at $349 and has won fans for its reliable tracking. The leaks show the Apex 4 keeping Coros’ straightforward design with wide bezels and a clear “Coros” logo on the front.
It will come in two sizes: a compact 42mm version for smaller wrists and a 46mm for those wanting a bit more screen space. The watch uses a Memory-in-Pixel (MiP) display that’s easy to read in direct sunlight without draining power quickly, plus a backlight for low-light workouts. This setup helps it stay visible during sunny trail runs or evening jogs without needing constant adjustments.
Performance gets a huge upgrade, with the new chip running 30 times faster than the Apex 2’s processor. This means quicker responses when switching apps, mapping routes, or reviewing workout data—no more lag during intense sessions.
For battery life, the 42mm model promises up to 41 hours of continuous GPS use for tracking runs or bike rides, while the 46mm stretches to 65 hours—a solid 62% improvement over the Apex 2’s 40 hours. Everyday use without GPS could last weeks, making it ideal for multi-day hikes or ultramarathons where charging isn’t an option.
New features add even more appeal for active users. Built-in speakers and a microphone let you take hands-free calls as long as your phone is nearby, perfect for safety during solo rides.
There’s also a dual-range barometer for more accurate elevation tracking— one sensor for small changes like stairs, another for big climbs like hills—helping with precise altitude data in apps like Strava. The watch keeps Coros staples like heart rate monitoring, sleep tracking, and navigation, but with smoother software and better sunlight visibility.
Prices are likely to be around $400 to $500 based on past models—the Apex 4 targets serious athletes who want long-lasting power without bulk. Titanium and sapphire materials hint at a premium build for durability in rough conditions.
Coros hasn’t confirmed the leaks yet, but the October 15 date aligns with their event schedule. If true, the Apex 4 could challenge Garmin’s Forerunner series with its speed and endurance focus. Fans can sign up for updates on Coros’ site— this might be the watch that redefines battery life for endurance sports.
