There are many different ways to classify types of watches.
Based on movement can be classified into 2 types quartz and mechanical.
Quartz watch is a type of watch having the manoeuvre mechanism with one “quartz crystal”. The crystal will oscillate when placed in an electric field, thereby supplying energy to such watch. Quartz watch is presently the most affordable one. It is primarily run on a battery.
Quartz watch Classified by places of manufacture:
– Swiss EB, Swiss Movement: As a type of movement with high precision and durability as well as good quality, generally installed for watches of luxury brands with very expensive prices. Therefore, although there are multiple watch brands not made in Switzerland but sealed the Swiss movement on their front side and back side. To do this successfully, that brand must ensure the following regulations: more than 70% details and accessories of watch movement manufactured in Switzerland; the watch movement compulsorily assembled in Switzerland and tested in terms of quality in Switzerland before being distributed to the markets.
– Japan Movement, Japan Quartz: As a type of movement manufactured in Japan or authorized the manufacture from the Japanese watchmakers. The quality of such watches is very good and their selling prices are relatively reasonable.
– Taiwan and China movements: Characterized by not high precision, low durability and cheap price as well as commonly used to install cheap watches.
Eco driver watch : This is the newest quartz watch technology, it’s using the light to recharge the battery so no need to change battery.
Mechanical watch run with energy from the main spring without using battery .
There are 2 types of mechanical watch is manual and automatic.
– Handwinding: As a type of watch that we must use a crown to wind at a certain time generally specified by hours or days (The number of turns for winding is subject to each type of watch).
Notes while using: When winding, the user only turns a crown at a suitable range or counts the number of turns up to 10-15. In case of turning too strainedly or at full size, it is possible to break the main spring or entangle the spring of such movement, thereby leading to the damaged movement.
– Automatic winding: The watch is wound as a result of natural motion of the wearer’s arm. Based on the theory of gravitation, a rotor turns and transmits its energy to the spring by means of an appropriate mechanism. In other words, it is unnecessary for the watch to re-charge energy by hand and use battery like a quartz watch. Such system was invented in Switzerland by Abraham-Louis Perrelet in the 18th century. The watch movements often have multiple jewels such as 17, 21 and 25. The above-mentioned two types of currently most popular movements are made in Switzerland (used for high-grade watches) or Japan (used for good-quality watches).
Note while using : The watch will automatically wind thanks to natural motion of the wearer’s arm; however, they must wear such watch regularly. Besides, for the automatic winding watches running more durably against the longer waiting period without wearing, you should wind the watch on a weekly basis by turning a crown at a maximum of 10 – 15 turns once a week.
