Thanks, Kevin!

Draw old companion (9)

I'd thought 'Good fellow' was maybe a British (hence, "polite") form of Goodfella, so I was stuck with don in ding.

On the plus side, I discovered from Lex that, for decades, I've worked off and on as a don. (It never dinged on me.)

I'm going to guess: DUPLICATE

To draw is to duplicate, and people call identical items (like matching socks) 'buddies' or 'mates'.

Could "old" be a surface word?

Good guess, but you'll have to try again, Helmer.

Direct on the left. Only 2 vowels, each used twice.

Oh for Pete's sake! (I'd failed to consider draw=tie.)

Don't you just hate it when that happens? ===[**CDM**]===

I'm getting used to it, ha. Thanks for the belt.

The answer is a device for keeping track of time.

That's a good answer, Sue! Here's your belt, made of pure gold. ===[**CDM**]===

So shiny! Thank you!

Approaches a hundred dollars spent (7)

a hundred = AC
dollars = KELTS
spent = anagram indicator

(Thanks for the money, encyclo.co.uk)

A very nice try, Helmer, and partially correct. An anagram clue must provide the letters to be anagrammed. They cannot be clued. You've got the AC right.
