The basic purpose of a standard watch is to let you know the time of day. As the watchmaker’s skills improved and customers began to demand more from their timepieces, the chronograph watches were developed. These replica watches are recognizable by even the most casual watchers of timepieces through their subdials, which add a sophisticated look to the watch face.
The chronograph is a professional name, in which Chrono means “time” in Old English and Latin, and graph means “recording tool” in English. A general replica watches continuously indicates the passage of time. The chronograph is different, and it can be recorded for any length of time.
The standard chronograph has a 30 minute or 12-hour timing function. The second hand in the center of the surface usually stops at the zero points. In order to display the time while walking, most of them add a constant small seconds hand. The chronograph can be equipped with as few as one or up to four sub-dial depending on the accuracy and design of the watch.
The most common calculation scale system in chronographs, usually located at the outermost periphery of the dial or above the outer ring of the case.
The main principle is: a certain unit distance is known, for example,1 km or 1 mile. When a moving object starts to move within this distance, the start function of the replica chronograph watches is started. When the unit distance is completed, the stop button is pressed.
The speed of this object is the scale indicated by the pointer. If the scale system is a single-turn design, the object speed is less than 60 km, the code table is invalid; the code table with the spiral design is not encountered. The outer ring of the watch with the function of the stopwatch will be engraved with 500/400/350. The number, the physical quantity represented by these is the speed in kilometers per hour; this bezel is called Tachymeter.
Most chronographs have mechanical movements, with the stopwatch as a complication, making them desirable pieces of craftsmanship and engineering. Quartz or battery-operated chronographs also exist, as do models that have a hybrid of the two.
