Choose from high, medium, or low conservatism settings to match your experience level.Higher conservatism gives you a shorter bottom time and a longer ascent time.

Whether you're using standard air or enriched Nitrox, the watch adapts to your mix - helping you extend dive times, reduce fatigue, and explore more with optimized safety and precision.

Your dive will automatically start when you are submerged 4’ to 5’ and will end when you surface.

When the watch auto-starts a dive, it will default to the last dive type you recorded — so if the last dive you recorded was a multiple-gas dive, it will start a multiple-gas dive.

Stay safe with real-time PO₂ alerts, which help you avoid oxygen exposure risks by notifying you when oxygen levels in your breathing gas approach unsafe limits - ensuring a safer, more confident dive.

PO₂ refers to the partial pressure of oxygen in the gas mixture you're breathing at a given depth.

As depth increases, so does the pressure, which can cause oxygen to become toxic if it exceeds safe limits.

Stay informed during extended dives with real-time guidance on how far you can safely ascend, helping you manage decompression more effectively.

Stay immersed in the experience without constantly checking your watch, while maintaining awareness of critical limits, supporting safer, more enjoyable, and distraction free dives.

Navigate underwater confidently with the integrated 3-axis compass. Simply press the down button to bring up the compass at any point during your dive.

The compass allows for adjustable heading settings and quick shifts to 90° right, 90° left, or direct reversal. It clearly displays your heading in both degrees and cardinal directions, helping you stay on course with precision.

See how long you can safely stay at your current depth without decompression stops, helping you explore confidently and surface safely.

After diving, your body retains excess nitrogen absorbed during time spent at depth. Flying too soon after a dive can increase the risk of decompression sickness, as cabin pressure changes at altitude can cause this nitrogen to expand more rapidly.

The No Fly Time feature tracks how long you should wait before boarding a plane, based on your recent dive profile including depth, duration, and decompression data. This helps ensure your body has enough time to safely eliminate excess nitrogen, reducing the risk of post dive complications.

With real time monitoring of your no fly period, you can confidently plan your next move, whether it's boarding a flight or preparing for your next dive - while keeping your safety a top priority.

Amazfit dive features are powered by the trusted Bühlmann ZHL-16c algorithm, providing precise calculations for tissue saturation, no-decompression limits (NDL), and decompression needs. By analyzing depth, dive time, and breathing gas composition, it accurately tracks how gases are absorbed and released in the body under pressure.

Divers can adjust the conservatism level to suit their personal fitness and specific dive conditions, ensuring a safer and more personalized underwater experience.

This industry-respected algorithm delivers reliable and transparent dive data, helping you dive with confidence.

TTS stands for Time to Surface, a crucial safety metric for divers that calculates the estimated time needed to ascend safely to the surface, taking into account your current depth, dive duration, and any required decompression stops. This helps ensure that you avoid decompression sickness, also known as "the bends," by allowing your body to release excess nitrogen safely during the ascent.

The TTS readout is dynamic, meaning it continuously updates in real-time based on your dive profile:

• If you go deeper or remain at depth for a longer time, the TTS will increase.
• As you ascend and complete required stops, the TTS will decrease accordingly.

This real-time guidance allows divers to stay aware of how long it will take to safely return to the surface without exceeding safe ascent rates or skipping decompression requirements.

Make every dive safer with automatic safety stop alerts designed to protect your body as you ascend. As you approach the surface, your watch will prompt you to pause at a recommended depth—typically around 5 meters (15 feet)—for a few minutes. This Safety Stop allows your body to release excess nitrogen more gradually, reducing the risk of decompression sickness and supporting a smoother transition from depth to surface.

By guiding you through these essential stops with real-time prompts, the feature takes the guesswork out of safe ascents, ensuring you're always aware and in control. Whether you're a seasoned diver or just starting out, Safety Stops give you added confidence, peace of mind, and a safer diving experience every time.

Stay informed with instant, continuous temperature readings as you dive, allowing you to adapt to changing underwater conditions. Whether you're monitoring for thermoclines or ensuring gear and suit performance, real-time temperature data enhances both your safety and comfort—helping you make smarter decisions and enjoy a more controlled, confident dive.
