When pushing the button on Withings Steel HR, the date is shown (to short) which then switches (to fast) to the current time.
When the screen is activated, the contrast ist not very strong (even on full light setting). So it´s very likely that you can not read/get the date bevor the screen switches to the time.
As the time is available on the watch anyway (analog),
can you switch the Setting (on first button push), to show first/short the time and then switch to show the date and keep it some seconds ?
