Once you perform the normal dive, the timer starts. In this time (24h) you can perform the deep dive and after that the bottom dive. When you have completed all three dives you are back to the normal dive. When the timer runs out before you complete the three dives you are also back to the normal dive. You can’t do the deep or bottom dive, before you have done the normal dive.
