With the advent of the crown, people no longer need to open the lid frequently to adjust the time, which greatly enhances the dust-proof ability of the clock. But in that era, the rubber ring and screw-in back cover had not yet been invented, the sealing of the clock was still poor, and external dirt was still easy to penetrate through the crown and other parts. Hans Wilsdorf, the founder of Rolex, initially solved this problem. He created the famous Oyster case in the early 20th century, which included a special screw-in crown and other patented technologies, which greatly improved the air-tightness of the watch. This has brought revolutionary changes to the watch industry. (In fact, there is a certain controversy in this history. Some people think that the screw-in crown was invented a long time ago, and Hans just pushed it forward.)Although this herb has nothing to do with Franck Muller's gypsophila watch, the flower language of gypsophila is also Franck Muller's gypsophila watch.
