Polar Electro

Polar makes heart-rate monitors, sports watches and fitness trackers, alongside training and activity software for athletes and other users. It describes its work as combining exercise science, physiological research and wearable technology to help people track training and understand their bodies. On its company page, Polar cites decades of patent and research activity; those scale and science claims are the company's own, not independent measures of product accuracy.

Suunto

Suunto is a Finnish brand of sports watches, dive instruments and compasses, tracing its story to Tuomas Vohlonen's development of a liquid-filled compass in 1936. Its own sustainability report says Liesheng has owned Suunto Oy since May 2022, when it left Amer Sports; the same report explains that manufacturing is split between Finland and a sister company in China, so 'made in Finland' should not be assumed for every device. Statements about durability or sporting performance are the brand's claims, not guarantees for each model.
