Is it possible to use the second couter, as a 60 second counter, like "normal" watches? It only use the second counter, when I use it as a stop-watch, and here it do like a 30 second couter.

The small dial at the 6 o'clock position is the normal 60 seconds counter.

The sconds hand in the middle is the chrono seconds counter which does only run for 30seconds before the 5 minutes counter adds 30 seconds and the seconds hand flies back to start again.

This is a feature of all the Retrograde watches.
