Listings show 40 mm, 41 mm, and 44 mm display sizes; exact availability depends on the specific model and configuration.

The listings specify a 50‑meter water resistance rating (ISO 22810:2010), which is suitable for swimming and other shallow‑water activities but not for scuba diving or high‑velocity water sports.

Product details list up to 18 hours of battery life and describe 'all‑day' use, with support for fast charging.

Safety features include Fall Detection, Emergency SOS, Crash Detection, and heart‑related alerts (high/low heart rate and irregular rhythm notifications).

Some listings highlight advanced sensors such as ECG, blood‑oxygen (SpO2), and temperature sensing; others emphasize continuous heart‑rate monitoring, irregular‑rhythm notifications, and sleep metrics (duration, quality, stages, respiratory rate).

Band materials shown include fluoroelastomer and nylon. When sizes are provided, they commonly appear as S/M or M/L; some listings note the material but don’t specify a band size.
