When you are going to buy a watch, you should know some basic knowledge about a watch which will help you get what you want. Here are 3 things you should know about before your buying-Complications,movements and sizes.

A complication refers to any feature in a timepiece beyond the simple display of hours and minutes. A timepiece indicating only hours and minutes is known as a simple movement. Common complications in commercial watches are day/date displays, alarms, chronographs, and automatic winding mechanisms. The more complications in a watch, the more difficult it is to design, create, assemble, and repair. A typical date-display chronograph may have up to 250 parts, while a particularly complex watch may have a thousand or more parts.

The movement, also referred to as the calibre, is the mechanism inside the watch that powers it. All in all, a watch would not function without it.  Modern watches offer two main types of movement- the quartz watch and the automatic watch. The majority of watches are quartz because they are cheap to make and very accurate. A quartz watch is powered by a battery to keep proper time. Now, watch enthusiasts will tell you that only real watch lovers choose automatic movement. An automatic watch is one in which the motion of the wearers wrist winds the spring. Mechanical movements are often chosen over quartz movements for luxury watches because of the level of quality and craftsmanship of mechanical movements. All great watch manufacturers including Rolex replica and Omega produce in-house movements that are duly tested before placed on the market. However, a quartz watch is actually more accurate than an automatic movement watch.

If you are a kind of thin but wide large wrist, you should choose the watch case index which is slightly less than 4. For the sporty watch and the diving watch, you can also choose the watch case whose index also is less than 4 without any problem; if you are a small wrist, you should not choose too thick watch; If the watch lug is too long, you should not choose the watch whose size is too big. Square case always look bigger than round watchcase, so the square watchcase index should be slightly larger. For the oval and rectangular watches, you can measure your wrist level. Choose wrist watch accord to the size of your wrist.
