What to know before buying

Battery life is claimed as up to 15 days in smartwatch mode and up to 20 hours in GPS mode. The listing says sleep, recovery and training metrics are estimates. Incident detection and Assistance require setup, a paired compatible smartphone and network coverage with data connectivity. The claimed water resistance is not a stated swimming rating.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title says 42 mm while the listed screen size is 1.1 Inches, and the dimensions are supplied as 9 x 11 x 7 millimetres. The details also list water resistance alongside an IPX0 waterproof rating, and LTE and eSIM alongside Bluetooth-only connectivity claims. The model name is Forerunner 265 while the title and box list specify 265S. Confirm the exact variant and relevant specifications in the selected listing before buying.

Frequently asked questions

How long does the Forerunner 265S battery last?

The listing claims up to 15 days in smartwatch mode and up to 20 hours in GPS mode. These are mode-specific claims, not a single general runtime.

Does this watch include built-in GPS?

Yes. The listing specifies built-in GPS and also claims multi-band GNSS with SatIQ technology.

Can it send safety alerts without a phone?

The listing says incident detection and Assistance need a paired compatible smartphone, setup, and network coverage with data connectivity. It does not describe these as phone-independent features.

Is it suitable for swimming?

Open-water swimming is listed among the activity profiles, but water-resistance details conflict with an IPX0 waterproof rating. Confirm the watch's water suitability before using it in water.
