Stopwatch function

Hello withings team

I like my steel hr whatch very much. Thanks for creating great looking and functional product.
I just missing stopwatch feature and would like to suggest it implementation.
How i image it could work is like this:
On watch screen long press to enter stopwatch mode
Then short press start/stop
Long press to reset
While in reset state (0:00:00)
Another long press to exit stopwatch mode

Thanks for your consideration
