Smartwatches aren’t for everyone. Maybe you don’t want to wear a screen-equipped gadget to bed, or you’re just after something that’s less obtrusive. Subtlety is where smart rings like the Oura Ring 4 shine, and Prime Day has knocked down its cost. It costs $296.65 ($52.35) from Amazon, which is both its best price and first significant discount.

In honor of Prime Day, Amazon is going against the norm with the first-ever price cut on Oura Ring 4: With a 15% reduction on all sizes, you can now buy the Oura Ring 4 in silver, size 10, for $297 from $349. Other sizes are also on sale, but some of them are already sold out.

For the first time ever, Oura Ring is marking down its latest iteration, the Oura Ring 4, for Prime Day. Men’s Health is pointing out this deal so you can score our favorite smart ring at a discounted price before the sale ends today.
