A diver must have full preparations before diving. A diving watch is necessary to prepare. Such a timepiece is different from other watches. A diver is surely familiar with it. It is a timepiece which is specially designed for people to having underwater diving.

Specialty of Diving Watches

1. Water Resistance

This is an obvious feature of diving timepiece. It is water resistant for about 300 meters. Divers do not have to worry about the quality of it after diving. As the technology of watch manufacturing is more advanced than ever before, it can go much deeper than it actually is. The diver can surely have a good time by wearing such a timepiece for diving.

2. Watch Case

Usually the case of a diving watch is more stoutly than other timepieces. It is made of special materials like plastics, synthetic resins, titanium and so on. And it must be able to endure the corrosiveness of seawater. The case of the special diving watch is relatively heavy and large when comparing with other watches. The commonest material for the watch case of it is the stainless steel.

3. Crystal

The crystal of a watch for diving is thick in order to enhance the pressure resistance of it. And the materials of the crystal are better in quality such as hardened glass and acrylic glass. These materials are more scratch resistant than other materials for making crystal.

4. Others
There must be a water resistant crown in such a watch. It is used by people to set or adjust the time and date. And the bezel is also unique with conspicuous 15 or 20 minute markings. The strap of such a watch is usually made of rubber, polyurethane and silicone rubber. And the battery of a diving watch is of electric powered movement.
History of Diving Watches
The watch was created before to meet military and professional needs. The Omega “Marine”, which was introduced in 1932, is said as the first Diving timepiece in history.
With more and more people realized how important it was to wear it for scuba diving, more and more diving watches were introduced into the market. In 1954, Rolex Submariner was introduced into the market. These watches are still attractive today.
During the 1960s, people had more under water activities. There were more watches designed for these activities. More and more watch manufacturers produced these timepieces at that time.
Today, scuba diving is loved by young people. Many people like to do it in their spare time. Either professional divers or not, they wear such a watch for diving. And famous diving timepieces are hot.

For most people, the proposal they buy watches is just for the timepieces functions or the beauty. In the past, fewer people buy those professional watches for daily wearing.

Today, the diving watches as one member of the sport watches in watch industry, it played an vital role in the sport watches and in the history of diving sport events.

Judged from the meaning of the diving watches, it means the watch can anti-water and used for diving sport in a great depth underwater.

Diving watches are set criteria issued by the ISO for what can qualify as a genuine Diver’s watch. This means that any watch bearing the legend ‘DIVER’S WATCH XXXM’ or ‘DIVER’S XXXM’ (where ‘XXX’ represents the depth) will have undergone a rigorous set of tests to guarantee that it meets the specifications.

These tests include a condensation test which is carried out before and after any other test-the watch is placed on a heated plate at 40-45°C and left for 10-20 minutes until it reaches this temperature itself. The a drop of water at room temperature (18-25°C) is applied to the crystal face, and left there for 1 minute before being wiped off. If any condensation forms on the underside of the crystal, the watch fails, and is immediately discounted from any further tests.

In order to become a diver’s watch, contenders also have to descend below their rated depth by a quarter again in still water, to allow for the varying densities of depth caused by weather variations and the fact that seawater is between 2% and 5% denser than fresh water. They will also be subjected to a thermal shock test, being placed in water at 40°C for an hour, then immediately into a container of water at 5°C, again, for an hour, then back into a 40°C bath for another hour. The longest test is one in which the watch is held 30cm underwater for 50 hours-more than two days. For this reason, most diver’s watches are made from steel or titanium, with ceramics and some plastics now becoming more common.

Other requirements are more to do with the practicalities of taking a watch under water. All diver’s watches are required to have a time pre-selecting device; the ability for the diver to see at a glance how long he has been underwater. In an analogue watch, this usually takes the form of a unilateral bezel-a bezel that can only move one way. Bezels such as this must have five minute intervals marked on them clearly, and have a scale of 60 minutes. The 60/0 minute mark must be visible on the bezel at 25m below the surface, as well as the time itself, so digital watches must have a backlit screen, and analogue watches need luminescent hands that are distinct from each other. They also need an indication that they are working, both at 25 metres and in total darkness, so analogue watches will usually have a ‘running’ second hand which has a luminescent tip.

With the help of internet, many online stores are selling bran-new and second-hand watches of outstanding quality at competitive price. They offer a wide range of watches of all famous brands like Longines Watches, Omega, Louis Vuitton Watches, Tag Heuer, Breitling, Oris Watches, Raymond Weil, Jaeger LeCoultre, Chanel, TW Steel, Longines, Panerai and so on.
