Oura Ring 5

Scale is the subject.

Oura Ring 5 is the smallest ring Oura has made, and this product page treats it as jewellery people choose, not as a gadget. Its width, 6.09 mm, is set in numerals cut from thin black sheet, and the ring hangs on the zero.

One continuous studio shot.

The camera swings round to show the band’s 2.28 mm thickness, window light moves across it for the six finishes, and it steps back to the zero for the close. A thin ring in the corner closes as the page goes on.
