## Before you buy

- Battery figures are mode-specific manufacturer claims. Health measurements are described as estimates, not medical readings. Smart notifications require a compatible smartphone, Garmin Pay requires a supported bank, and Pulse Ox is not available in all countries.

## A good fit for

- Divers who want one watch-style computer for recreational, advanced, technical, freediving and pool-apnea use.
- Buyers who also want GPS, activity tracking, health features and smartwatch functions for everyday wear.

## Less suited to

- Buyers who need a dive-mode battery duration beyond the listed up-to-27-hour claim.
- People who prefer a smaller watch. Customer feedback is mixed about the device's size.

## Customer feedback

Customer feedback highlights perceived strengths in features, fitness tracking, battery life, screen quality, data quality and sleep monitoring. The reported 10-day battery experience aligns with the listing's smartwatch-mode claim, but the listing gives a shorter, separate battery figure for dive mode. Opinions about size are mixed, so fit may be a deciding factor. Aggregate ratings are largely favourable, but do not explain individual experiences or establish performance in a particular dive situation.
- Positive themes: Customers report satisfaction with battery life, screen quality, data quality and sleep monitoring.
- Positive themes: Customer feedback describes the watch as useful for fitness tracking and praises its range of features.
- Mixed feedback: Customer feedback is mixed about the device's size.
