This watch has a unidirectional rotating bezel. As the evaluation of the remaining air in your cylinder is based on the information of the elapsed time of the dive, the rotating bezels for a diver's watch is designed to rotate only counterclockwise, so that the watch is prevented from displaying the elapsed time shorter than it actually is. CAUTION Make sure that you check the correct remaining amount of air in your cylinder before diving. Use the display of the elapsed time by the rotating bezel only as a guide during diving. How to use the rotating bezel ① At the start of the activity, for which you want to measure the elapsed time (for example, when you start diving), rotate the bezel so that the mark on the bezel is aligned with the minute hand. ② Read the graduation on the rotating bezel to which the minute hand is pointing. ʲ&Yʳ8IFOZPVTUBSUEJWJOHBU 4UBSUPGUIFEJWF "GUFSNJOVUFT "MJHOUIFɹNBSL IBTFMBQTFE XJUIUIFNJOVUF IBOE 3PUBUJOHEJSFDUJPO PGUIFCF[FM &MBQTFE UJNF 3FBEUIFHSBEVBUJPOPOUIFSPUBUJOHCF[FM UPXIJDIUIFNJOVUFIBOEJTQPJOUJOH 33
