TL;DR: Suunto has launched the Vertical 2 watch. Get it from Amazon for $599.

There's a new fitness tracker on the market, and it's something for endurance athletes to lust over. Finnish brand Suunto has announced the Vertical 2 watch, officially hitting shelves on Oct. 15. It's described as an "advanced adventure watch", designed with serious endurance sports in mind.
This model has seen the heart rate sensor fully redesigned. It now gives you far more accurate stats across training, recovery, and health tracking. It also has a new processor and expanded memory, so things should run much faster.
There are 115 sport modes to choose from, all with advanced training analytics, weather alerts, altitude data, and further stats. It even has offline maps and climb guidance — maps guide you through unfamiliar terrain, and climb guidance assists you in navigating hilly or mountainous ground through real-time elevation profiles. Users get color coded route sections and pre-warnings of climbs or descents.
The key to any endurance watch is the battery life. The Vertical 2 promises to last up to 65 hours with GPS tracking and up to 20 days with general smartwatch use. Perfect for multi-day treks or races.
Style-wise, the Vertical 2 has an impressive AMOLED display, keeping everything bright and colorful, even in direct sunlight. And whether you pick the steel or titanium option, this watch is seriously robust and is able to cope with all manner of activities.

The Suunto Vertical 2 is available to buy right now. The stainless steel version comes in at $599, and is available in a huge range of colors including black, canyon, and sage. The titanium version retails at $699, and comes in black or sage colors. You can find both options from Amazon.
