Swim-proof design
Fitbit Versa Smartwatch, Gray/Silver Aluminium, One Size (S & L Bands Included)
Best for: Users who want lighter aluminium color
Important points to consider:
Colour and case finish are the only real differences from the black Versa. Apart from that, every function is the same. So the whole decision lies on aesthetics and not features
The silicone strap is included but can show wear faster in humid climates than premium bands that are sold separately
Expect Fitbit to prioritize newer models for future software support
The included 6-month premium membership requires activation within a limited window after setup and applies to new premium users only, so if you delay you will miss out this opportunity
Built-in Alexa and Google Maps require a paired smartphone with location or data access
The Versa 4 skips ECG and EDA sensors entirely, so buyers expecting Sense-level health tools should check the feature list before buying
