The Citizen Dive Watch

scuba diving

Keeping track of the time is very crucial for someone who is seriously into diving. Citizen Dive watches would be the perfect choice for any diver as they have special features that any standard waterproof watch wouldnt have. These features include easy read dials, increased resistance to pressure and added protection from salt water to avoid deterioration.

To ensure that you can safely return to the surface when diving, a divers watch will be needed to keep track of diving activity. A diving watch that is stylish enough to wear when diving isnt the main priority or if you intend on having a good swimming competition against others is also wonderful to have. The recommended watch for all occasions is the Citizen Divers Watch which has an attractive lineup of watches with all sorts of styles and uses.

Choosing the Features

In terms of style and quality, you are certainly headed in the right direction if you have your eye on any citizen diving watch. But before deciding on your next Citizen dive watch, there are some important things to take into consideration.

First and foremost, you need to look at the maximum depth that you intend on diving up to. Most Citizen diving watches are capable of reaching a depth of 200 meters with the exception that no helium gas is used. There are also many other Citizen Dive models available for a dive up to 300 meters where helium enriched environment is evident.

The entire range of Citizen diving watches have that common easy to read bevel, which is important for clear readability underwater when accurate timing is needed of the divers time underwater. But each Citizen Dive watch has its own specific style. Some models have a non-reflective crystal face to allow for perfect clarity when being glanced at and this includes the Citizen Promaster SST.

To avoid being underwater for more than the intended time, it is crucial to take a glance at the time every now and then. The Citizen Promaster SST is the ideal choice as it has 24 hour timing with its chronograph accurate up to 1/1000th of a second which makes it ideal for racing purposes as well. There are also advanced Citizen Dive watches available for more serious divers who want to keep track of the number of dives that they have done.

Choosing the Style

Citizen dive watches have a balanced line up of luxury looking watches to the sporty looking ones. The lower end Citizen Dive watches are pretty suitable for both diving and standard wearing, but the Citizen Promaster SST manages to have digital and analog elements along with a nice stainless steel bracelet for that professional look. It may not be as rugged as the other designs, but it saves you from changing watches during special occasions.

Overall, the Citizen Dive Promaster SST has a great balance of features and excellent accuracy in tracking time. The other Citizen Dive watches are just as good and will definitely compliment divers in life threatening situations. No diver should go without wearing one and only Citizen Dive watches have all the elements of accuracy, durability, style, and versatility.

Dangers of Diving

Diving has exposed the public to the many underwater wonders of the world. The beauty of the various kinds of life that is in the deep blue hides the biggest danger of diving. It isn’t sharks or boats or anything else that may exist on or in the water. The real danger to divers is Caisson disease, or decompression sickness.

Also known as the bends, the disease can afflict anyone who goes from a high pressure to low pressure environment. The illness results from Henry’s law, which says in short that when the pressure goes down, gas will form bubbles in a fluid. In the case of the bends, the fluid is the blood and the gas is typically nitrogen.

When the process occurs slowly, such as in an airplane cabin, the lungs can remove the gas before bubbles form. When it occurs quickly, such as a diver coming up too fast, it can result in itching skin and rashes, pain in the joints, paralysis and potentially death.

Prevention of Bends

Preventing the bends requires the diver to ascend slowly, allowing the gas to naturally de-gas. The number of variables to consider when calculating the time needed for slow surfacing makes it very difficult to determine. That is why the dive computer was invented. With its specialized timers and sensors, it can determine how deep the diver is and how long the diver was at that depth. A diving computer conducts its calculations in real time and determines how much time the diver needs to spend at a particular level to surface safely and prevent the bends.

Just about every brand and model of dive computer possesses the capability to sense the time that a diver has been at different depths. From this data, the dive computer can calculate the divers blood gas levels and give the diver a time interval within which the diver can resurface safely and not worry about the bends. It provides all the necessary information for a safe dive, such as surface time intervals, maximum dive depth, water temperatures and so on.

The Diver Interface

Many forms of divers computer will have visual displays, which should be clearly read and visible while diving. The display of the dive computer should be uncluttered, so the diver does not experience information overload. In addition to the above information, better models of diving computers will display information such as the temperature of the water, the required decompression time at each depth and how fast the diver is rising. Many higher end models will transmit the entire dive to a computer for later analysis.

Certain defining features can really set a dive computer ahead of the pack. By the time a diver has surfaced, high end dive watches will display the time before a diver can board an airplane. One of the quickest ways to get the bends is to board an airplane too soon. High end models are also able to keep track of the air supply in the scuba tanks.

When it comes to shopping for a dive computer, the consumer should identify how much information is provided on the display and if the display is clear and readable. They should also see what other features there are and what is being kept track of in terms of diving quantities. An excellent example of a quality diving computer would be the Suunto D9.
