Newlyweds Prince Harry and Meghan, Duchess of Sussex, have given fans plenty to rave about as they tour Australia this week — from baby news to a slew of public engagements to the very first sighting of a baby bump.

But eagle-eyed royal watchers have spotted something else worth a closer look: Harry's new ring.

While the prince has worn a simple platinum band on his left ring finger since he swapped vows with his bride in May, he now also wears a thicker black band on his right ring finger.

And that new bit of jewelry appears to be a smart choice — as in smart tech.

According to reports, the Duke of Sussex is believed to be sporting a wearable sleep and activity tracker from Oura.

The ring, which is billed as "the most accurate, comfortable and beautiful wearable available" on the company's website, appears to be from the brand's Heritage collection and is either the black option (which retails for $299) or the nearly as dark stealth option ($399).

You can snag a more affordable version from a company called Motiv.

But the real appeal isn't the looks of the accessory, it's the function.

Hidden inside the ring are infrared LEDs, a body temperature sensor, a 3D accelerometer and a gyroscope, all of which work together to track sleep time and quality, as well as logging steps, sedentary time and more.

All of which sounds like a good idea for a prince who'll soon add daddy duties to his busy schedule.
