Because the gap between the screen and watch body is so thin, an iFlex is needed to separate the two.

Protect your fingers by keeping them completely clear of the iFlex edge. If in doubt, protect your free hand with a heavy glove, such as a leather shop glove or gardening glove.

Be careful not to apply too much pressure, as this might cause the iFlex to slip and cut you, or damage the watch.

Wear eye protection. If the opening procedure is performed incorrectly or with too much pressure, the glass could crack, sending small glass shards flying.

Attach or remove the watch band as needed to provide more control as you make repairs.
