Clock face with second hand for Charge 6

[Startingtostep]

I am a veterinarian with the Charge 6.  To record heart rates I need both of my hands while looking at my wrist.  I see that other Fitbits have an option to give you an accurate second hand and will stay on for longer to allow this (I see others call this a nursing clockface). Is there a way to change my clockface, either within the app- none of the clockfaces I see have an readable second hand! - or from a third party?

@Startingtostep   The clock faces that you see in the Gallery are the only ones available for the Charge 6.  There are no third party clock faces for the Charge 6 or any other tracker.  Fitbit Fitbit didn't release a software development kit for third party development for apps or clocks faces for trackers.

Do you think you could find a workaround using the timer or stopwatch?
