[Time Setting Warning Function] (Analog Display) The watch stops when insufficient charging continues for about 1.5 days. When the watch is charged by exposing to light after having stopped due to insufficient charging, each hand is rapidly advanced to the base position and stops. Each hand remains stopped until the time is reset. (Digital Display)[...]

When power is not generated as a result of the solar cell not being exposed to light, the second hand stops when it reaches the zero seconds position and the watch automatically enters the power save state to inhibit power consumption of the secondary battery. (Analog Display) • The second hand stops at the base position (12:00). • Other hands [...]

20. Using the Register Ring NOTE: The bezel design may vary depending on the model. [Calculation function] A. Navigational Calculation 1. Time required Example: Obtain the time required for the fight of an aircraft at 180 knots for 450 nautical miles. Answer. Align'18’ on the outer scale with the SPEEDINDEX / on the inner scale. Then, "[...]

scale (time scale), Thus, the estimated flight time is 2 hours and 30 minutes. 7. Difference in altitude The difference in altitude can be obtained from the rate of descent and the descent time. Example: Obtain the difference in altitude when an aircraft continues descending for 23 minutes at a rate of 250 feet per minute. Answer. Align"25&quo[...]

3) Proportion Example: 30/20 = 60/x Operation: Align "30" on the outer scale with ‘20’ on the inner scale, Then, ‘60’ on the outer scale corresponds to ‘40’ on the inner scale. At this point, the proportion for every value on the inner and outer scales is 30:20. 4) Square root Example: Square root of 225 Operation: Turn the ou[...]
