The manual itself says 9 hours, which is not far from the 8 hours and 45 minutes that our device provided before its battery died on the 15th hole of the second testing round. At least that’s what it says on their web site. Callaway claims 10-12 hours of battery life while using GPS.There were some elements of the interface that didn’t really click with us (primarily surrounding the press/hold distinction), but nothing that you don’t eventually learn through repetition. Navigating through the functions of the GPSync relies upon four buttons on the sides of the watch, as well as learning the difference between a “press” and a “hold” of a button.Two “keeper” loops hold the excess length of the band in place and adjusting them to the correct position is somewhat critical in preventing the band from rubbing against you during your putting stroke. The watch body is black and the accompanying rubber band is black as well. The Callaway GPSync weighed in at a surprising 2.35 ounces (as tested), which made it the heaviest golf GPS watches we have tested.875”, giving it about 0.77 square inches in viewing area – a hair smaller than the 0.8 square inches available on the Garmin watches. Callaway lists the screen size for the GPSync as 1.28”, which is the diagonal measurement.

Once you’ve gone through the setup process, just charge up the battery and you’re good to go.Note that you have to manually enable the watch’s Bluetooth function (by pushing one of the watch buttons) every time you power the watch back on. The pairing process was pretty simple, and once paired, the watch and the mobile app will share completed scorecards and you will receive notifications of incoming text messages (the watch will display the entire message, not just the name of the sender), telephone calls and calendar invitations.

IZZO has apparently discontinued its own line of Swami watches in order to avoid cannibalizing sales of the GPSync. The Callaway GPSync Watch is actually produced by IZZO and marketed under the Callaway brand pursuant to a license agreement.
