The Citizen Promaster Eco-Drive Aqualand Diver BJ2120-07E BJ2120-07BJ2120 Men’s Watch is the most refined timepiece in the Citizen Eco-Drive Aqualand Diver watch series. It is also available in the BJ2120-07 and BJ2120 models. This particular model has Tritium gas tubes that, in addition to the long-lasting power provided by light energy from the sun or artificial sources like fluorescent lamps or LED lights powered by natural or artificial light sources such as solar cells, provide illumination in darkness and low light conditions.
The Citizen Promaster Eco-Drive Aqualand Diver BJ2120-07E BJ2120-07 BJ2120 Men’s Watch is a dive watch that features a 48mm case, water resistance of 200 meters, Super Luminous hands, Tritium gas tubes for illumination in darkness or low-light conditions, a day/date function, and a screw-down crown. Additionally, the watch is equipped with a day/date function.
This one is not for the sluggard or the couch potato in any way, shape, or form; ideally, you need to be into major outdoor and/or aquatic sports in order to do the Aqualand Diver properly. It has been given an ISO certification; it is equipped with a light-powered Japanese quartz movement; and it can function faultlessly for a whole sixty days on a single charge of its power reserve.
A luxurious timepiece that will force you to venture out into the wilderness. I needed a watch that could withstand water depths of up to 200 meters, have a date display and a second hand, and have a black dial and bezel.
The reliable Citizen Promaster Eco-Drive Aqualand Diver BJ2120-07E BJ2120-07BJ2120 Men’s Watch includes a unidirectional bezel, and its stainless steel case houses the well-known Calibre G870 movement. This watch is designed for use in the harshest environments possible.
The light source has a significant impact on the nature of the Eco Drive function that is included in this model. Although they have been tested and certified in a wide variety of geographic locations, their optimal performance can be achieved either in the presence of direct sunlight or within a fluorescent lamp (which does not necessarily require a continuous supply of light). These are the two types of light sources that are currently utilized by solar-powered watches.
