Watchface Design Expression Help

I’m trying to program a textual clock face that displays O’ if the leading zero is a ZERO.

Any ideas how to type that formula, if possible?

You mean if a number is less than 10?

$#tag#<10?O:$

Yes, Thank you! – I don’t know why that was so hard for me to put together.
