If you want to reduce maintenance burden, drop binary, fuzzy and LCD. 
They are all there only mostly "because we can" and IMHO are just bloat.

Try the following custom formats:

%a, %d/%m%n<b>%H:%M</b>
<small>DE: %H:%M (%a)</small>

More details about formatting commands:

Some features (e.g. font_face) don't seem to work here but overall the 
capabilities are pretty good.

Available in the clock plugin via custom formats.

Currently an update is forced once per minute and afaik there is no an 
easy way to change it without waking up the plugin more often. An easy 
workaround is to include seconds in the clock format.
