Initial developments focused on the Galaxy Watch 8, which introduced an ‘Antioxidant Index’. This feature utilizes a BioActive Sensor to perform multi-wavelength absorption spectroscopy via a thumb scan, estimating fruit and vegetable intake by detecting carotenoid absorption. Following this, Samsung launched the Galaxy Watch Ultra 2 and Galaxy Watch9. The Ultra 2 is a rugged model designed for extreme environments, featuring high durability ratings for diving and specialized modes like ‘Trail Run’. It also includes a ‘Nutrition Alert’ system for hydration guidance. The Galaxy Watch9 offers a lightweight aluminum design.
