This Casio men’s watch was designed for those who work and play in the sea. The Casio AMW710-1A Moon Data Graph watch includes a moon phase indicator and a tide graph to help map marine tides and schedule marine adventures. Once the high tide has been entered for a selected location, you can view local low and high tide phases on any date. This is essential information for fishermen (or surfers) to carry on the wrist and to know the marine patterns at their upcoming destination in advance rather than have to search other sources for this information. This men’s marine Casio model is water resistant up to 100 meters (classification 10 bar) and keeps track of time on both water and land with the one-one hundredth of a second stopwatch. It has three alarms and a second zone. You can set the watch to a second zone. The current location is read as analog and the second location is displayed in digital format. The Casio’s timing function is precise to one-one hundredth of a second in 24 hours. Elapsed, split and final time are also digitally measured by the Casio with a similar accuracy of 1/100 second. The Casio can measure up to 24 hours. The countdown reminds you of specified events by emitting an audible signal at a preset point. It can count backwards automatically from the preset. The alarm can be set to the nearest minute and up to 24 hours in advance. This is a useful function to remind people to take medicine or do a specific task at a several exact minute each day. This Casio’s three independent multifunctional alarms can be set in four different ways. Firstly there is the daily alarm, which sounds at the same instance each day and secondly there is the date alarm to remind you of birthdays and anniversaries. Then there is a monthly alarm, which can be set to sounds on the same day at the same instance each month so it might be helpful to remind to pay bills or do other tasks. The final alarm can be set for every day or certain of the month. On each occasion your alarm goes off it will sound for a few minutes but there is also an easy touch snooze feature. The button tones for using the mode button can be turned off so you don’t have to hear the audible longer beeps when switching between different functions. Your preset timers and alarms continue working when the button tones are turned off. The Casio Moon Graph watch also has an automatic calendar that always displays the correct date, and you can view it in either a 12-hour or 24-hour format. It is constructed from a black resin steel band with a black and orange stainless steel and aluminum bezel case. This synthetic resin is an appropriate material for this type of wristband because it is extremely durable and flexible. There is a light-emitting diode (LED) to illuminate the analog watch face, which will help you see in dimmer marine waters. There is also a luminous coating, which provides long-term illumination in the dark after only a short exposure to light. The men’s watch face is covered by a tough scratch resistant mineral glass to protect it from all marine type of situations. Casio AMW710-1A marine watches for men have a long battery life of up to 10 years thanks to newly developed electronics, which ensure lower energy consumption. These Casio AMW710 marine watches were designed with the professional or sports fishermen, surfer, or sailor in mind.
