The two variations of the Forerunner 35 successor have been steadily leaked over the last couple of months, but have now been made official by the company.
Unlike Garmin's other new wares - the Forerunner 245 range and Forerunner 945 - the 45 and 45S are instead aimed at running beginners, with heart rate monitoring and GPS both being used to provide feedback on pace, distance, intervals and more. The recently introduced Coach plans will also be supported.
The difference between the two is simply the case size; the 45S features a 39mm shell, while the regular 45 offers a slightly bigger 42mm face. And, as the images indicate, the big change here is the departure from the rectangular casing of the Forerunner 35, with a circle (more in like with the rest of the Forerunner family) now being used.
However, the new pairing haven't just been designed for runners. Exercise modes also exist for cycling, elliptical, cardio and yoga workouts, and, of course, general activity tracking will log users daily steps, calories burned and sleep. There's even the incident detection feature that debuted on the Vivoactive 3 Music.

Smartwatch features include smart notification support for incoming texts and calls, as well as the ability to control music playback from a paired smartphone. Battery life for both the Forerunner 45 and 45S should up to seven days in regular mode, Garmin say, and 13 hours when using GPS.
Both the 45 and 45S are available to buy from today, with all variations available for $199.99.
