I have a suggestion, Atomic Alarm Clock, http://drive-software.com/
I can synchronize it with an atomic clock and I can change how it looks easily.
Screen Shot:
I've been using T-Clock for a few years now. No longer being actively developed unfortunately but the available 2010 version does work with Windows 10. Customisable text as regards the font chosen, bold and colours. Different time formats can be chosen, short or long day (Thurs or Thursday), 24 or 12 hour clock:

Edit: I notice on the page linked to that someone other then the original developer has taken on the project and there is a later version available if required.
Or another one 1st Clock 5 . isnt free but isnt expensive either and it is fully customisable.
