The Fitbit Versa 4 is water-resistant up to 50 meters, which makes it suitable for swimming in shallow water conditions, such as pool swimming. However, it is not entirely waterproof, and its water resistance can diminish over time or be affected by various factors like exposure to chemicals, high-velocity water, or physical impacts[1][3][9].
In real-world swimming conditions, many users have reported successfully using the Versa 4 for swimming without issues, provided they avoid diving or exposing the device to excessive pressure[2][3]. It's important to note that not all straps are suitable for swimming; for example, leather bands are not water-resistant[1]. Fitbit recommends cleaning the device with fresh water after swimming in saltwater and drying it with a lint-free cloth[1].
While the Versa 4 does not have a dedicated water lock mode, starting a swim in the Exercise app automatically enables a form of water lock to prevent accidental screen activations underwater[1]. Despite these precautions, some users have experienced issues with water damage, often related to factors beyond the device's intended use, such as diving or prolonged exposure to water[2][7].
Overall, the Versa 4's water resistance is reliable for casual swimming in shallow water, but users should be cautious about its limitations and maintain the device properly to ensure longevity.
