It is designed to keep working despite the motions caused by the persons activities.腕表是由一個人佩戴的小的計時器,它的設(shè)計是通過表帶戴在

2、手腕上,目的是保持工作，而不受人的活動影響。Functions1 Show time 顯示時間2 Personal adornment 個人裝飾品3 Collectible works of art 收藏品4 Specific functions 特定功能Classification1 Mechanical watch（機械表）Manual mechanical watches (手動機械表手動機械表)Traditional mechanical watch movements use a spiral spring called a mainspring as a power source.

3、The spring must be rewound periodically by the user by turning the watch crown.Most modern watches are designed to run 40 hours on a winding and thus must be wound daily, but some run for several days and a few have 192-hour mainsprings and are wound weekly.(傳統(tǒng)的機械表機芯使用一個螺旋彈簧稱為發(fā)條作為動力源。彈簧必須定傳統(tǒng)的機械表機芯使用

5、ural motions of the wearers body.It uses an eccentric weight, called a winding rotor, which rotates with the movement of the wearers wrist.The back-and-forth motion of the winding rotor couples to a ratchet to wind the mainspring automatically.Self-winding watches usually can also be wound manually

6、to keep them running when not worn or if the wearers wrist motions are inadequate.（自動腕表由穿著者的身體的自然運動倒帶機械機芯自動腕表由穿著者的身體的自然運動倒帶機械機芯作為作為動力動力，它采用偏心它采用偏心重塊，稱為一個繞組轉(zhuǎn)子，其與穿用者的腕的運動旋轉(zhuǎn)重塊，稱為一個繞組轉(zhuǎn)子，其與穿用者的腕的運動旋轉(zhuǎn)，繞組轉(zhuǎn)子耦合到背繞組轉(zhuǎn)子耦合到背面的往復(fù)運動棘輪以自動纏繞面的往復(fù)運動棘輪以自動纏繞主主發(fā)條發(fā)條，自動上鏈腕表通常也可以手動上弦，自動上鏈腕表通常也可以手動上弦，來使手表正常運行，防止佩戴者不戴手表或者手腕運動
