Suunto support’s reply provided some additional details:
The Suunto Run does not include all the swimming features advertised in the product sheet — a deliberate choice by Suunto. I don’t understand why they don’t update their product sheet to clarify which features might actually come later; it’s completely unacceptable.
Suunto acknowledges these shortcomings. It’s somewhat reassuring — we can hope for certain improvements, such as displaying distance in meters — but nothing guarantees that all the announced features are achievable due to hardware limitations (automatic laps, stroke recognition, rest-time counting). I was told that only the high-end models are capable of handling these features and that the Run is primarily oriented toward running.
