Hamilton watches are known for their classic styling and longevity. However, over time, scratches and dings can mar the appearance of your watch. Fortunately, there are a few steps you can take to restore your Hamilton watch case to its original luster.

1、使用钢丝刷。将轻轻的钢丝刷放在手表表壳上，刷起来时要慢慢转动，使得划痕慢慢消失，但不要用力过猛，以免表壳损伤更大。

2、使用工具磨砂。将一把软布放在表壳上，将湿磨砂料撒在布上，然后用手按着布，用轻轻的圆周运动方式把磨砂料轻轻擦拭。

3、用橡皮筋轻轻擦拭。拿一根橡皮筋，把它放在表壳上，用轻轻的擦拭方式，把划痕轻轻的擦掉，直到它们消失为止。

4、使用牙膏。将正常的牙膏塞满表壳上的划痕，然后用软布轻轻擦拭，直到划痕消失为止，重复几次直到满意的效果出现。

5、用汽油或香水。将汽油或者香水滴在划痕上，然后用一张纸巾擦拭，不要用硬毛刷，这只能把手表表壳刮掉。

These are just a few of the many ways you can restore your Hamilton watch case. With a little time, patience, and effort, you can bring your watch back to its original condition.
