Description
Fitbit Versa 4 is a fitness-focused smartwatch for people who want training, sleep and stress data on the wrist. It sits in the Versa line and suits everyday wear as well as workouts, with a modern look and a grey silicone strap.
The square case is stainless steel and carries an AMOLED display. Water resistance is rated to 50 m, and the watch connects over Bluetooth 5.0 to iOS 15 or higher and Android 9 or higher phones. Built-in GPS, heart rate monitoring and a sleep monitor sit alongside notifications, calls and text messaging.
The standout is the breadth of health tracking: Daily Readiness Score, Active Zone Minutes, 40+ exercise modes, Sleep Score and a Stress Management Score. Fitbit Pay, Alexa built-in and a battery rated at 6+ days mean it works as a daily companion, and a 6-month Premium membership is included for eligible users.
Frequently Asked Questions
Can I swim with the Versa 4 in a pool?
Fitbit Versa 4 is water resistant to 50 metres, so lap swimming in a pool and showering are fine. It is not meant for diving or high-speed water sports. Rinse it after chlorine or salt water and dry the strap to keep the silicone comfortable.
Is it enough for my daily running and gym sessions?
Yes for most sport use. The Versa 4 has built-in GPS, 24/7 heart rate, Active Zone Minutes and 40+ exercise modes with automatic exercise tracking. That lets you run without a phone and see real-time stats, which suits regular gym and outdoor training.
How does the Versa 4 compare with a standard Wear OS smartwatch?
The Versa 4 puts fitness, sleep and stress insight first and lasts 6+ days on a charge, versus roughly a day or two for many Wear OS watches. The trade-off is a smaller app ecosystem. Choose Wear OS or an alternative if you want many third-party apps.
Which phones work with it and does it handle calls?
It pairs over Bluetooth 5.0 with iPhones running iOS 15 or higher and Android phones on Android 9 or higher. You can take Bluetooth calls, read texts and get notifications on the wrist, and Fitbit Pay and Alexa are built in.
Will the square case suit a small wrist?
The Versa 4 has a square stainless steel case with a flexible silicone strap, which usually fits a wide range of wrists comfortably, from slim to larger sizes. It weighs about 190 g in its packaging, so the watch itself is light enough for all-day and overnight sleep tracking.
How do I look after the battery and service of the watch?
Charge it roughly every 6 days and avoid temperatures outside the -14 to 113 F operating range. The battery is not user replaceable, so any service goes through Fitbit. Wipe the case and strap regularly to keep the sensors clean for accurate heart rate readings.
Editor's take
Fitbit Versa 4 is aimed at people who treat a watch as a training partner first and a timepiece second. It carries a stainless steel square case and a grey silicone strap, and the Versa line has always leaned toward approachable fitness tracking rather than rugged outdoor kit.
The feature that matters most day to day is the built-in GPS, which lets you leave the phone at home for runs and rides. Alongside it sit 24/7 heart rate tracking, Active Zone Minutes and an AMOLED display that stays readable outdoors. The 6+ day battery is a real advantage over most full smartwatches.
The limits are in the details. Water resistance is rated to 50 m, which covers pool swims and showers but is not a dive specification. Premium features such as the readiness score depend on the 6-month trial included, and the platform is a Fitbit ecosystem rather than a full Wear OS app store.
It suits fitness-minded wearers who value sleep and stress insight and long battery life over app variety. If you want a broader app ecosystem, a Wear OS or Apple Watch alternative is worth a look, whilst a simpler band-style tracker covers basic step counting for less.

Stainless Steel Case, Glass Front
The Versa 4 pairs a stainless steel case with a Corning Gorilla Glass 3 display cover, a combination chosen for scratch resistance in daily wear. The case reference FB523SRAG-US is finished in silver, which suits both gym sessions and office cuffs without drawing attention.
Silicone Strap for Daily Wear
The silicone strap is soft, light, and easy to rinse after a workout or a swim. It holds firm on the wrist during movement yet stays comfortable through long days, and the quick-change design lets you swap it for another Fitbit band when the occasion calls for it.

Rated to 50 Metres
Water resistance of 50 metres covers pool laps, showers, and rain, which is the practical range for most swimmers and athletes. It is not a dive rating, so keep it away from high-velocity water and hot environments such as saunas. Rinse the silicone strap with fresh water after exposure to salt or chlorine.
