Driving is known as the coexistence of the brave and dangerous sport excise, with strong features. When people driving under by the impact of water pressure, the pace of life continues to slow down, gravity, the downward acceleration, increasing the color level, are constantly challenged to divers. In such extreme circumstances, a reliable watch is the primary prerequisite and guarantee security, and a timer, add to the fun of diving.

Under extreme environments in the sea, a reliable watch is the primary prerequisite and guarantee security, and a timer, add to the funny of diving entertainment.

When the calendar turns to the best time happy sea journey July, diving watch is the super star of the watch industry. Appearance, Geneva wave decoration black dial, sleek lines and orange scales; craft, unidirectional rotating bezel, helium escape valve, of course, the most critical of a few hundred meters water depth, are people instantly think of ocean diving The spirit of adventure. Are your diving watches ready to enjoy under the sea?

Not the simple water resistant watch is a diving watch.
The waterproof function does not mean simply that professional diving watch, according to the Swiss watch international standards (NIHS) the provisions of the watch must meet certain specific standards, be called the diving watch. To determine whether a watch is a professional diving watch or not, need to know the followings:

1, the safety device control dive time
NIHS92-11 (ISO6425) standard dive watch dive time must have control of the security device. In addition, in order to prevent interpretation errors, the device must prevent inadvertent inadvertently rotating with the design. Watch engraved with the detailed minutes of the best equipped diving with the time scale of the rotating inner ring. The inner ring rotating control device should also have appropriated safety boot design.

2. Clear and Easy to Read the Digital
Time, rotating inner diving time, the movement is running or not which it is can be clearly identified in the reading in the dark deep-sea environment instructions. Usually the distance (straight-line distance watch with the eyes) is set to 25 cm. Among them, the fluorescence process is the most common major form of business solutions.

3. Waterproof and Salt Water Corrosion Resistance
To ensure the core components of the watch and strap soaked in salt water environment which does not has any change, the waterproof liner dive table, mirror and bottom case with components should be adjusted accordingly, common practice is increasing the thickness. NIHS92-11 standard dive watch case should reach over 100 meters of water depth.

4. Anti-magnetic, Shockproof and Against Temperature Changeable Characteristics

Professional diving watch with anti-magnetic protection equipment is extremely sensitive which devices to the balance spring, because of the magnetic field affect the destruction of their precision. Anti-magnetic protection device allows movement from magnetic fields, vibration and temperature changes, thereby ensuring accurate travel time watch. Also need to watch for temperature tests, if there hasn’t found any steam condensation means the watch is a good diving watch.

5, The Characteristics of External Force
At last, the watch wrist components should be able to bear under 200N external force. For example, the way of Audemars Piguet watch is to enlarge the buckle of the standard watch tighten, in additional, it takes use the rubber watch wrist which to bear the high external forces.
