依我看 16570 側面鏡面亮光 錶圈、表耳髮絲處理 週邊有倒角 只是表耳下側未倒角 連接彈簧棒處有點銳利--這也是判斷新舊錶的地方 其實 錶殼打模是非常精緻的 |
〝連接彈簧棒處有點銳利--這也是判斷新舊錶的地方〞
這句話我不甚了解,〝連接彈簧棒〞?您可以解釋再清楚些嗎?

This is a good comment (from TimeZone) on the material that ROLEX uses:
"Most watch manufacturers use stainless steel 1.4435 or 316L. Rolex uses stainless steel 1.4439 or 904L which is slightly different from 1.4435. Steel 904L and 316L have the same grade of hardness. The level of nickel discharge with 904L is slightly higher, causing an increased chance of allergic reaction when worn by people sensitive to nickel. While technically 904L is more corrosion resistant, this is typically a concern is in industrial applications using steel in equipment for handling chlorides, sulfur dioxide gas or other toxic materials. Almost no watch manufacturers except Rolex consider it worth using the 904L steel, especially given that the price for 904L is approximately three times that of 316L." |
