Edit image 1. Keep everything — both children, their faces, helmets, suits, the glowing blue hologram of the submersible with the pressure arrows, the dark water — exactly as it is. Change only Kira's watch on her left wrist: replace the black rugged watch with Kira's watch from image 2 (the left wrist in image 2): a slim light-grey band and a rounded-square screen glowing soft purple-violet; the hologram rises from this screen. No other watch on her. No text.
