石英表和機械表有什麽區別？

從根本上說，石英表和機械表最大的區別在於驅動兩者的動力來源不同。石英表是通過電池發出的電力來“刺激”表內的石英晶體，使它產生規律的振動來驅使時針和分針運行，因為石英的震動非常規律，所以石英表的走時也會比機械腕表準確很多，壹天的誤差率不會超過壹秒。

手動上鏈機械表是通過表冠的轉動驅使輪系運行來將遊絲旋緊，再通過遊絲的自然舒張使得擺輪轉動，並帶動其他部件也壹同轉動，從而實現腕表運行的目的。自動上鏈腕表則是加上了壹個有重量的擺輪，讓腕表能夠在人手運動的時候為機芯上鏈，從而帶動壹系列的齒輪傳動。

機械表可分為手動和自動兩種：
（1）機械表依靠手表機芯的上弦發條提供動力,不需要電池。
（2）機械表走時與石英表不同，機械表秒針是連續不間斷地走。
（3）因機械表機芯復雜，走時誤差較大視各品牌而定。
（4）工藝精細，使用方便，上足發條可走36小時以上。機芯使用年限長久。
（5）外觀要比石英表厚重壹些，有壹些品牌也很薄,但壹般都是手動機械表。

石英表可分為數字式、指針式及自動石英表和光動能手表：
（1）石英表的走時秒針是壹格壹跳,走時十分準確。
（2）機芯中采用集成電路，結構較機械表機芯簡單許多，裝配非常簡便。
（3）使用方便，佩戴無需上發條，壹塊電池壹般可用2-3年。但有些石英表用鋰電池,使用壽命長,可用7-8年左右。
（4）石英表價格相對比機械表便宜。
