Citizen has been making Eco-Drive Promaster divers watches since the early 1990’s. They are very rugged and well made watches made to take a beating and also they easily can withstand 200 meters in depth for diving.
The nice thing about Eco-Drive divers watches is that you never have to open the back to replace the battery. The solar cell in the watch only requires 8 hours of direct sunlight in order to be fully charged and will run for 6 months with no need for more light to re-charge it. Since you do not have to replace the battery every 2-3 years like most regular divers watches there is much less chance of damage to the back gasket which could result in water leakage when swimming or diving.
Many people love the fact that they can go to the beach or to the health club and swim in the pool and take a sauna or relax in the hot tub and not have to worry about getting water into their watch. These watches are perfect for any outdoor activity or sporting event. Citizen Eco-Drive the watch that goes everywhere that you want to go.
