Wearing the Watch

2. The diving features are intended for certified divers only. Ensure you have received professional training and understand how to operate the device. General users engaging in breath-hold training or other diving activities must be accompanied by a coach, an experienced dive buddy, or a professional.

Always dive with a professional dive computer or other backup device. Do not rely solely on this device for critical decisions like planning decompression stops or determining no-fly times.
7. By using this device, you acknowledge and accept that it serves as an auxiliary tool and does not guarantee absolute accuracy or suitability of data, nor can it eliminate inherent diving risks. Always prioritize safety, make reasonable dive plans, and take responsibility for your personal safety.
