In this review, we’ll look at its key features, performance, and provide a practical Garmin Swim 2 battery replacement guide for long-term users.
Garmin Swim 2 Features and Performance
Swim-Focused Tracking
The Garmin Swim 2 excels in both pool and open-water modes. It supports distance, pace, stroke count, stroke type recognition, SWOLF efficiency scores, auto rest, structured workouts, and critical swim speed (CSS). With underwater wrist-based heart rate monitoring, it eliminates the need for an external chest strap.
Multi-Sport Support
While designed primarily for swimmers, the Garmin Swim 2 also supports running, cycling, and basic cardio workouts. In addition, it tracks daily activities such as steps, calories, stress levels, and sleep quality.
Design and Display
The watch comes in a 42mm case with a 1.04-inch sunlight-readable color display. Its five-button navigation makes it easy to operate underwater, while the silicone strap provides comfort and durability. The 5 ATM water resistance rating ensures it can withstand depths up to 50 meters.
Battery Life
- Smartwatch mode: up to 7 days
- GPS with wrist heart rate: up to 14 hours
- Pool swim with wrist heart rate: up to 72 hours
These figures make it one of the most battery-efficient swim watches available. However, like any wearable, long-term use may eventually require a Garmin Swim 2 battery replacement to restore full performance.
