What to know before buying

Listing details to confirm

Listing details conflict on water protection: one field says “Not Water Resistant”, while another lists a depth of 50 Metres and a separate field gives IPX7. The specifications table preserves the required water-resistance entry, but buyers should confirm the intended rating before exposure to water. The page also gives an 11-day general battery figure alongside mode-specific claims of up to 11 days in smartwatch mode and up to 19 hours in GPS mode. The title says 43 mm while the screen is listed as 1.2 Inches. These are listing discrepancies, not confirmed product defects.

Customer feedback describes a good-quality sports watch, with positive reports about workout and run tracking, battery life and condition. Reliability feedback is mixed, including reports of multiple buttons stopping working. That concern is relevant because the watch combines button controls with its touchscreen, while the listing's battery claims vary by operating mode. These reports are customer perceptions, not a guarantee of any individual renewed unit's condition.

Frequently asked questions

How long does the battery last?

The listing claims up to 11 days in smartwatch mode and up to 19 hours in GPS mode. These are mode-specific claims, not a single unconditional runtime.

Can it track runs without a phone?

The watch is listed with built-in GPS for pace and distance. The described incident detection and Assistance features, however, require a paired compatible smartphone and network coverage.

Can I listen to music without carrying a phone?

The listing says songs and supported playlists can be downloaded to the watch for listening with wireless headphones. Subscriptions are required for the named streaming services.

Is the renewed watch water resistant?

The listing is inconsistent, giving “Not Water Resistant”, 50 Metres and IPX7 in different fields. Confirm the applicable rating before buying if water exposure matters.
