No much reps can survive 3 bar... That's why we don't recommend to take your rep to any place with diving into water. After we upgrade the waterproof it can barely survive 2-3 bar. Without the treatment, it can only live with daily life waterproof. I will soon do another post about this . Do you want to send the watch back to repair it?This one exploded after 5 bar. A second identical one fails at 1 bar.
