Note Dec 2020:
Personal testing of Fitbits that have battery issues suggest a possible issue
that this clockface uses more battery than the thin-lettering on the official clockfaces
as more pixels are lit.
Please do not use with the brightness turned up to full for long periods of time,
to preserve the health of your Fitbit battery.
This may be an issue with Fitbits not being able to support large numbers of pixels lit for a long periods of time on any clockface, this legible clockface can still be used but care should be taken not to turn the brightness to full.
If you are a glasses wearer and are not wearing reading glasses, this is still a simple and easy to read clockface on your Fitbit Iconic or Versa.
The free 'Easiest' easy to read digital clock face, with the English date using the correct suffix (e.g. '1st January') is available for download.
