What do you suppose this dial is all about? I’m not bidding on it, just curious

I'd vote for industrial Time & Motion stopwatch (or other manufacturing/laboratory function). Hundredths of a minute for the central hand, minutes on the sub-dial. Single pusher to start, stop, reset, notice the gap at the base of the crown.

I don’t remember which railroad it was. Their official time standard recognized 23:59:59 and 0:01 as being midnight. Perhaps the 0 fits in there, somewhere. But the subject watch is not a “watch” in the typical since, but more of a timer for a dedicated purpose. Heuer at one time made a stop watch on which the sweep hand travelled in the clockwise direction, but the numerals on the dial went counter clockwise. It was used in broadcasting, and IIRC was called a “count down timer”. Anything’s possible.
