With thanks for all the valuable info and the suggestions.
As and update:
I will stick to the Bolt and will not buy any sports watch right now. They just seem super expensive and compared to the price dont convince me looking at quite a lot of criticism about accuracy etc.
I have attached the Bolt to a nice little wristband which I can hook to my backpack etc or can use as a stand when rowing or doing gym workouts - this way all is readable and supports me nicely in my workouts.
Thank you all for your support.
