Time is a very important factor in our lives. We use it for various purposes and even use it to measure various things. In order to keep track of time, it is important for us to have watches. There are many different types of watches out there, for different purposes. Some of the examples include exercise watches, dive watches, fashion, designer, mechanical, and many more. These are all watches that are designed with features to assist the users in some functions related to their use. In this article, we are going to be reviewing a diver watch. Research on watches that could be used by divers began as early as the 17th century and by the 19th century, they were being produced for explorers and adventurers. In the 1930’s, dive watches began being produced for commercial purposes in Switzerland. Many of the diver watches back then were made to military expectations and were used before and after the world war.
Dive watches are made with a unidirectional bezel that divers can use to show them how long they have been in the water and if they need to get out for a change in oxygen tanks. Being that they will be used under the water, the time pieces usually have a huge display. The display also comes with a lit or luminous features so that it can be read in the dark abyss of the water. When in a water body, the upper part usually has light and the watches are easily readable. However, the deeper that you venture into the water, the darker it gets, and the harder it gets to read the watches. It is very important for one to be able to read the watch because their life practically depends on it while in the air. Oxygen could run out when you are hundreds of feet in the water, and it could turn tragic. Despite the fact that professional divers nowadays employ the use of wrist worn computer devices to monitor the time and depth in the water, watches always come as a good backup.
In this article, we are going to be looking at the Citizen Men's BJ7000-52E Nighthawk Stainless Steel Eco-Drive Watch. A serious timepiece for the serious watch collector, the Citizen BJ7000-52E stainless steel men's watch offers powerful timekeeping functions for your favorite aeronaut. The large round watch case measures approximately 43mm in diameter. It has a thin silver bezel the houses a black dial with a pilot's inner rotating slide rule bezel, which is operated by the secondary crown at 8 o'clock. It has large luminous hands and markers for readability and low-light visibility and dual time (GMT) capability. The triple link bracelet band is composed of brushed silver stainless steel pieces, and it's joined by a push-button folding safety clasp. Other features include a water resistance to 660 feet (200 meters), low-charge indicator window, power saver function, and a scratch-resistant, non-reflective mineral crystal.
When you first take a look at the face, it looks very complicated but the hands are bold and you quickly adjust to it. It also comes with a flight reader that can confuse many people that are not pilots or navigators. The overall look of the dive watch is very appealing and it can be worn by people that are not necessarily divers, pilots or navigators. The band is made of stainless steel that will not rust on you any time soon. It is also long enough to wear over large wrists or a dive suit. A crown on the watch controls the movement of the bezel, which is smooth when you adjust. You can use the slide rule for division, multiplication, unit conversion, and rate/time/distance calculations.
There is also a GMT face on the left side (from 6 to 12) with white & red numbers. There is a separate, double-ended hand with a red-tipped and white-tipped indicator. Out of the box it shows the 24-hour time (white for 00-12 and red for 13 - 24). You can set this to a different hour to have a true GMT indicator.
The light on the watch is nice and bright - a blue color which is different from the traditional green shade. You can read the watch in the dark because the hands are luminous, which I especially good for those that go into the deep sea. Under the water, the deeper that you go, the darker it gets, and the more that you need a watch you can read in the dark.
