Oura debuts smaller, more discreet Ring 5 in South Korea to challenge Samsung’s Galaxy Ring

Oura launches its latest Ring 5 in South Korea, featuring a smaller design and advanced health tracking, directly competing with Samsung’s Galaxy Ring in one of Asia’s most tech-savvy markets.

Oura will make its formal debut in South Korea on 25 August with the local launch of the Oura Ring 5, bringing the smart-ring maker into direct competition with Samsung’s Galaxy Ring in one of the world’s most brand-conscious wearables markets.

According to Edaily, the company is partnering with Lotte to run a dedicated pop-up store at Lotte World Mall in Jamsil from 25 August to 7 September, where visitors will be able to try the device and buy it in person. The ring will also be sold through Oura’s official online store, Lotte’s online mall and Naver Smart Store.

The new model is designed to be smaller and more discreet than earlier versions. Oura says the ring measures 6.09mm wide and 2.27mm thick, and uses a low-profile sensor dome, high-output LEDs and 12 signal pathways to improve readings across different finger shapes and skin tones. Overseas launch coverage from Forbes and other technology outlets said the Ring 5 is about 40% smaller than the Oura Ring 4 and went on sale globally in late May, with shipping beginning in early June.

Oura says the ring tracks more than 50 health metrics, including sleep, activity, stress and women’s health. The companion app turns that data into scores and personal insights, while members can access features such as menopause guidance, hormonal contraception support and live activity tracking. The company has also added a harder PVD coating and says the ring is water-resistant to 100 metres and dust- and water-resistant to IP68. It is available in black and silver for 630,000 won, with gold, stealth, brushed silver and deep rose priced at 780,000 won.

The launch sets up a clearer contest with Samsung, which is positioning the Galaxy Ring as part of a broader device ecosystem linked to Samsung Health, phones and watches. Oura, by contrast, is leaning on its longer experience in sleep and recovery analytics, as well as a jewellery-like design aimed at consumers who want health tracking without a smartwatch. George Abbott, Oura’s regional head for Europe, the Middle East, Africa and Asia-Pacific, said South Korea is a key market and that the company plans to expand local reach through accurate measurement, heart-health tools, pregnancy tracking and design.
