Beautiful device, but not the first calculating machine by a long shot. That would be the antikythera mechanism [1].

I think the distinction is that Antikythera was a calendrical device, but couldn't perform multiplication/division etc of a given number like the device described here.

Naturally. This would be more accurately described as the first mechanical calculator.

“Calculation” literally means moving little pebbles around on a counting board to solve discrete numerical problems.

If anybody is interested in the construction of this device, definitely check out ClickSpring on YouTube. He's doing a full build and also exploring techniques and materials that might have been used way back when.

Just saw this device in person, it was gorgeous.

These videos are fascinating!

Do you mean that you saw the ClickSpring reconstruction in person, or the Antikythera mechanism at the museum of Athens ? If it is the former, how far is it from being complete ?

Sorry for the confusion, I was recently in Athens and saw the Antikythera mechanism in person. That said I'd love to see ClickSpring's version in person once it's completed!
