杭州宝玑走时1965年，Cosmograph手表得到了进一步的发展，用旋入式计时码表取代了原来的抽气按钮。钛金属具有熔点高，硬度大，可塑性强，密度小，耐腐蚀等优点，而且比贵金属与不锈钢来得轻，因此超薄加上钛合金的运用，让这枚手表上手格外显轻。杭州宝玑走时#NME?

If the top surface of the cover hole of the Rolex mechanical watch strip is skewed, the grinding tool shown in the figure (Figure 2) can be used to reduce the time deviation of the watch. When using this tool, the birch can be inserted into the barrel cover hole and the iron hole, so that the tool can be perpendicular to the barrel wheel, and the oil stone can smooth the inclined surface. The picture is a schematic diagram of the inclined surface of the grinding barrel wheel. If the gap between the barrel shaft and the barrel wheel and the barrel cover is too large, the barrel cover can be placed on the punching hole, so that the barrel cover hole tube is loosely punched into the punching hole, and the plane punch is vertical. Flush the upper middle part of the box cover slightly downwards to adjust the gap. It is also possible to punch the barrel wheel, but the metal tube should be inserted into the barrel wheel. The above method can reduce the time failure of the watch.What they are looking for is not to make the watch function more complex, but to make the ordinary watch more precise.
