Overview

• The diver, 26-year-old Mumbai-based Flipkart engineer Kshitij Zodape, began an uncontrolled ascent at about 36 meters when his weight belt came unstuck in choppy, low-visibility waters.
• The Watch Ultra detected the rapid rise, issued on-screen warnings to slow the ascent, then triggered its emergency alarm when the climb continued.
• The piercing siren, specified by Apple as two alternating high-pitched tones audible up to 180 meters, drew the instructor back to stabilize Zodape.
• Reporting notes the intervention likely prevented lung over-expansion, decompression sickness, or even a boat-strike risk in the fishing zone.
• Zodape said he hadn’t known the watch had a siren and had been using it with the Oceanic+ dive app, while Apple continues to spotlight these safety features with its latest Ultra model.
