Watch Detail

Click the Capture to track the accuracy of this watch, or review the Timing Stats or History of previous recordings.

Capturing

Record the face of your watch until one of the hands crosses a marker, e.g. the second hand crossing a minute marker.

For best results, move the watch as close as possible to the camera without it being blury, and try to hold still.

Review 1: Frame

Rewind the video and then navigate forward and pick the first frame where the hand reaches a marker, in this case, where the second hand reaches 43.

Pan the video around with your finger to center the watch, and zoom in and rotate to allow for best legibility.

Review 2: Time

Read the time shown in the picture of your recorded watch and adjust the "Watch Time" numbers accordingly to match it exactly.

Once you have made a couple of recordings over several days, the app will attempt to guess the Watch Time by pre-adjusting it based on the Best-fit Rate.

Review 3: Details

Review the total offset of your watch, and the rate per day.

You can also tag the recording with the position and usage of the watch, or some short additional comment.
