Garmin Approach S72 expands its rollout: what the new wrist-based swing metrics really measure

Garmin announced the Approach S72 golf smartwatch on 6 October 2026. Sales began in Japan and the Philippines on 22 October, extending its rollout to two more markets. US recommended pricing starts at $799.99. Its notable change is not merely a more premium case: Garmin is trying to make a watch worn during a round useful for examining swing mechanics.

What do the swing metrics measure?

The S72 reports hand speed, backswing length and wrist rotation. These are measurements associated with the movement of the wrist wearing the watch, not direct measurements of ball speed, ball spin or the clubface at impact. Those outcomes generally require different measurement methods. Treating a wrist metric as interchangeable with a radar launch monitor’s club or ball data would be misleading.

A plausible use case is structured practice on the range. Golfers can follow whether their backswing gets shorter, whether wrist-movement tendencies change and whether a pattern becomes more repeatable. Garmin says range activity can be recorded in Garmin Connect and counted towards fitness activity. A smoother graph alone, however, does not establish that dispersion or carry distance has improved. Those outcomes still need to be checked against actual shots or separate instruments.

Green reading and putting analysis

With an active Garmin Golf Membership, golfers can view green contour information on selected courses, including the likely break direction and average slope. Garmin also describes post-round putting analytics such as speed bias, direction bias and make rate, alongside aerial imagery for course management. These premium features are subscription-dependent; course coverage is not universal. A paid membership should not be interpreted as a guarantee that every green has contour data.

The new golf biometrics allow a player to look back at heart-rate trends before and after shots and compare them with round results. That can provide personal context, but a relationship between heart rate and score is not proof of causation. Garmin also explicitly states that the watch is not a medical diagnostic device.

Hardware and battery

The S72 comes in 43mm and 47mm sizes, each with an AMOLED display, titanium bezel, sapphire lens and ComfortFit fabric strap. Garmin has added a speaker and microphone for calls and voice interactions, a first for its golf-watch family, as well as a built-in white/red flashlight. For the larger 47mm model Garmin quotes up to 20 hours in golf mode and up to 16 days in smartwatch mode with GPS turned off. These are published maximums, not battery endurance we independently measured.

Who needs it?

The appeal is a combined view of wrist motion, on-course decisions and daily activity. Someone seeking measured launch angle, ball speed or spin still needs a launch monitor. For golfers who want to monitor the consistency of their hand motion and keep a connected training diary, the new metrics may be useful—provided they understand what they cannot measure. This is a technical analysis of the manufacturer’s information, not an independent accuracy test.
