How to choose a suitable watch from Different types of watches.

Choosing a watch is so overwhelming. There are so many things to consider. Aside from style, which is so diverse, there are countless features you want to take into account. Here are some things which might help you narrow down your options so you can find a watch that bests suits your style and needs.

SPORT WATCHES
There is a wide selection available to meet the demands of an active lifestyle. Divers watches, also called Marine watches, are specially formulated to withstand the pressure of deep sea diving, reaching depths as great as 2000 meters. Most divers watches come with basic features including water resistance, a unidirectional rotating bezel (for timing the amount of oxygen you have left in your tank) and brilliant luminescence. Equally ergonomic are the Pilot watches, also called Aviator watches. Specifically designed to meet the navigational needs of pilots, pilot watches are capable of performing all calculations a flight plan requires.

Chronograph watches are also suitable for sports. A chronograph watch is a multi-function watch with a stopwatch function. Most chronograph watches have two or three subdials for measuring hours, minutes, and seconds. Chronograph watches are made with both quartz and automatic movements.

LUXURY WATCHESSometimes referred to as Haute Horlogerie, luxury watches are great for collectors and watch connoisseurs. Luxury watches are for those who appreciate expert watch movements and exquisite handcrafted complications that are encased in superior materials and precious gems.

DIAMOND WATCHESIf you are looking for a functional piece of jewelry that can help dress up an outfit, a diamond watch is the way to go.

QUARTZ WATCHESIf you are looking for a watch you can rely on for accuracy, we would recommend a quartz watch. You never have to worry about winding it or wearing it in order for it to work.

In Quartz watches, a specially designed battery activates a Quartz crystal inside the movement that vibrates approximately 33 times per second. These vibrations translate into impulses by a computer chip that drives an electronic motor, which moves the watch's hands.

MECHANICAL WATCHESIf you are the type of person who appreciates mechanical things, or the beauty of the complications found in a mechanical movement, a mechanical watch is right for you.

There are two different types of mechanical watches on the watch market. Mechanical and self winding automatic. Mechanical watches typically run for about 40 hours on one full winding of the mainspring. The power reserve on a watch indicates how much time a watch will function when not worn, or until it is wound up again. Few watches on the market today can run up to 8-10 days without being wound. Some prefer to use a watch winder so that their automatic watch can run continuously without being worn.

Manual: In a manual watch, the wearer must turn the crown (button on the outside of the watch's case) to wind the mechanism.

Self Winding Automatic: In a self-winding or automatic watch, you do not need to wind the mechanism, you just need to wear the watch. The movement in an automatic watch is activated by a rotor, which turns by the force of gravity with the regular movements of the wearer's wrist. Automatic watches are more or less reliable, although at their worst, they can gain or lose about 10 seconds per day. An automatic timepiece needs to be worn for about 10-15 hours until it is fully wound. COSC certified automatic movements (called chronometers) are tested by the Swiss Official Chronometer Testing Institute ("Contrôle Officiel Suisse des Chronomètres") and can gain 6 or lose 4 seconds per day (-5/+8 for watches with a diameter greater than 20mm).

WATER RESISTANT WATCHESWatches used to be deemed "waterproof," however, the International Organization for Standardization prohibited the use of the term waterproof. They also issued a standard for water resistant watches. Water resistant watches are made up of special gaskets which form a watertight seal. A sealant is applied as well, to help keep the water out. The material of the case is also tested to pass as water resistant. Watches are tested for water resistance in still water. It must be noted that a watch with a certain meter rating is tested for water resistance under still water, with the watch being stationary . It does not take into account if the watch can withstand the pressure that is generated by motion at that depth of water. It is important to keep this in mind when you are purchasing a water resistant watch.

If your watches water resistance is not measured in meters, you can approximate it's resistance by multiplying BARS or ATM's (atmospheres) by 10.

General Guidelines are as follows, but keep in mind that it depends on a specific watches recommendations. Check your watch manual before using near water. Always remember to make sure your crown is pushed/screwed down before immersing in water!

Water resistant - Will tolerate splashes of water or rain (usually resistant to 24-30 meters/100 feet)
50 meter/165 feet - Usable while showering, bathing, dishwashing, and swimming in shallow water (immersion without pressure)
100 meter/330 feet - Usable while swimming, general water sports and snorkeling (surface swimming)
150 meter/500 feet - Usable during swimming, general water sports and snorkeling
200 meter/660 feet - Usable during general water sports, including free diving (skin diving without scuba gear)
300 meter/990 feet - Usable during general water sports, swimming, and scuba diving (to depths which do not require helium gas)
1000 meter/3300 feet - Usable during scuba diving to depths greater than 500 Meters - the limit of human endurance.
DIVERS 150 meters/500 feet - Meets ISO standards and is suitable for scuba diving
DIVERS 200 meters/660 feet - Suitable for scuba diving but not professional deepwater diving
