Having said that, you don’t actually need to put the watch in dive mode, as it will automatically start tracking your depth once it is taken about a meter under water or more. It would have been great if Citizen allowed you to keep the watch in chronograph mode so that the orange hand stuck at the top of the dial. It is a useful feature and shows that Citizen is focused on safety, but again it is really only necessary when diving – which is an argument to keep the watch with your dive gear (albeit in light so that it is charged when you want it). LV.1 means that there is charge for about one hour of diving at a maximum depth of 20 meters, and Lv.2 means you are good for all types of diving (within the functional range of the watch). The battery indicator is segmented into three areas that are “LV.2, LV.1, and NG.” I assume the latter means “no go” because it is a warning that the battery is not charged enough to sustain the depth meter function when diving. If you put the watch into chronograph mode, it eventually reverts back to battery level indicator mode. That means that rather than be symmetrically aligned at zero, the orange hand is always oriented a bit to the left. Chronograph mode must be entered into by pressing down on the lower pusher. It is negative because the timepiece uses the central orange hand as the power reserve indicator by default – not as the chronograph seconds hand. This is both a positive and negative feature. The watch essentially includes a warning system designed to let you know if there is enough battery power to dive. What’s next? Stay tuned for the latest in revolutionary styling from Citizen.These latter two functions are important to understand because they work together.
With the presentation of the Eco-Drive Satellite Wave at Baselworld 2011, Citizen has re-affirmed its position as a worldwide leader in timekeeping technology. In 2007, Citizen introduced radio controlled atomic-timekeeping watches in the world.
With models ranging from dress to to sport to professional dive watches, Citizen Eco-Drive runs continuously in any kind of natural or artificial light for a lifetime of use. More recently, Citizen has become the leader in Ecologically Friendly timekeeping with its Eco-Drive collection of light powered watches. From the world’s slimmest LCD watch to the first voice recognition watch and the world’s first professional dive watch with an electronic depth sensor, Citizen’s record of “world firsts” is unmatched. Beyond sheer size, Citizen is also recognised as a worldwide leader in advanced technology. Recently, the company has risen to be the world’s largest watchmaker, a distinction Citizen has held every year since 1986.
