Strange numbers on wristwatch dial

What are these little numbers around the rim of the face/dial on my watch?

It starts with 60 at the top, then there's an arrow to the right, and then this sequence: 600, 500, 400, 330, 275, 240 (and it goes on from there). I'm curious as to what purpose these numbers serve.

Best answer: I think tachymeter is a better answer.

Response by poster: Thanks! Interstimg that it's included on this particular watch, which doesn't have a second hand

Yes it is a tachymeter, which is useful on a chronograph. To use it, you really need a chronograph second hand (which you can reset to zero, start, and stop with the press of a button).
On your watch it is just an affectation, as is the stamped fake-guilloche dial. Sorry.
