What to know before buying

Listing details to confirm

Battery duration depends on operating mode. The listing states up to 10 days in smartwatch mode and up to 15 hours in GPS mode. Green contour availability is limited to select courses and requires an active Garmin Golf app membership. The technical details call USB the wireless connection while separately listing Bluetooth and Wi-Fi under communication features, so the connection details are inconsistent. The listing also gives two differing dimensions, 1.65 x 1.65 x 0.51 inches and 0.5"D x 1.65"W x 0.53"H. Confirm the intended connection details and dimensions before purchase.

Who is it for?

A good fit for

Golfers who want course maps, on-watch distances, scoring and shot tracking in a smartwatch.
Buyers looking for a 42mm golf watch that also lists general fitness activity profiles.
Golfers willing to use a Garmin Golf app membership for green contour data or add optional CT10 sensors for additional tracking.

Less suited to

Buyers who need green contour data without a qualifying membership or on courses outside the stated select-course availability.
Golfers seeking all listed automatic game-tracking functions without buying optional CT10 sensors.
