Because of military needs, diving watches were invented. Also they were invented for people who dive for a living. Technomarine watches are used in this manner.

Diving watches must be water resistant at least to one hundred meters or three hundred thirty feet. Most can go up to nine hundred feet or three hundred meters. However some can go much deeper.

All of the diving watches sold should pass test standards. These watches get to call themselves diver’s watches which distinguishes them from other watches that can be used in the water. Watches without this distinguishing mark are not suitable for scuba diving activities. Using them underwater may break them.

During the sixties, ocean work for pay called for a heartier watch that would survive great ocean depths. First the ultra water resistant watch was manufactured. Divers now look to electronic dive equipment. Diving watches are a backup if the dive computer breaks.

The International Organization for Standardization sets the standard for diving watches. Not just any watch may be used for intense underwater work. They will break.

The watch cases of diving watches must be water resistant and be able to endure the harshness of seawater. The cases are generally made out of corrosion resistant materials. The watch case must also provide an adequate degree of protection against magnetic fields and shocks.

The outer part of diving watches need to be stronger than dress watches because it has to stand up to salty sea water and the pressure of deep oceanic work. However, they are made from materials like stainless steel, titanium, ceramic, resins or plastic. The case has to protect against magnetic fields, bumping and shock.

Diving watches have elapsed time controllers on the bezel. Analog diving watches have a rotating bezel, that allows for an easier reading of elapsed time and to compute the length of a dive. Diving watches have thick crystals. Sometimes it is domed. Materials used for crystals are able to withstand intense pressure under the sea.

The cases of some diving watches have oil inside the crystal to prevent breaking under the pressure of the deep sea. Some diving watches are filled with air or helium to stop them from breaking. Diving watches filled with air have to be larger to keep from breaking under pressure. Professional divers sometimes save lives and when lives are at stake they cannot afford to have their equipment break underwater.

The makers of diving watches say that divers should have the watch checked professionally every so often. They say to take it to an authorized watch repair shop every few years to have the seals replaced. The watch can be placed in fresh water after a dive in the sea to protect it from corrosion and to make sure the crown and buttons and pressure sensors are working.

Technomarine watches are to be treated as a piece of equipment used for diving. Inspecting the men’s watch before and after every dive ensures that there are no mishaps when in use.
