Just like an analog clock.

I believe the large (blue) hand advances one mark around the perimeter for
every engine hour.

In 60 hours, the large hand will accomplish an entire circuit of the gauge.

The little hand (white) keeps track of the number of 60 hour increments.

I think the meter reads 505 hours.

I might be wrong, but it looks like 530 hrs to me.

25 (the big blue needle on the outer 0 to 60 hrs scale) past 480 (the
white needle on the out of focus ... er fuzzy ... inner 0 to 600 hrs green
scale) = 505

504 hours and 52 minutes. There are 3 hands. Green reads 480 hours (just
past by almost 25 hours). Blue reads 24 hours (almost 25 hours based on 52
minutes). White reads 52 minutes.

Catch is - has it already been around once which would add another 600
hours? (or twice)

I think you're right, except the white hand is a minute hand. (I should have
mentioned that it moves one RPM.) The little green hand that's partially
visible behind it is the slow hand, I think. Notice that it's pointing on
the 480 side of the space between 480 and 540. I would think that it should
be closer to halfway, but maybe that's an illusion.

Any idea what the pattern of blue tick marks indicates?

One other point....connect it to power for an hour
or ten to verify which hand(s) move over that time
period.
