The screw down crown introduction

 

    Hello, hope you had a nice weekend. It's already 10:30am Monday of our local time.

   Today, will introduce the using of the screw down crown. Usually there are 2 kinds of crown. One is the common crown, you just need pull it out, then wind and adjust the time. The other kind is the screw down crown. This crown can't be pulled out, you need screw it, then it will pop out, then you can pull out a little to adjust the date, when adjust the date, turn the crown toward your face, after pulled the whole crown out, you can adjust the time. Here is the video for your reference. 

 Which kind of crown you like? The common one or the screw down crown? Thank you for your time.
