About the crown of a pocket watch

The crown is a key part of a watch that winds the mainspring and adjusts the time and date. The word originates from "ryuuto," a Japanese watch term. In English-speaking countries, it is called "crown" or "krone." *We mainly use the term "crown" in our shop.

By the way, the ring part of the crown through which the chain or string passes is called a "ring."

Mechanical pocket watches have a mainspring that is wound up with the crown. Therefore, in the case of mechanical watches, the crown must be wound at the same time every day. Of course, the time is also adjusted with the crown.

Although there are exceptions, in most cases with mechanical pocket watches, you simply turn the crown to wind the mainspring, and generally pull the crown up one notch to adjust the time.

As the name suggests, quartz (battery) watches are powered by batteries, so there is no need to wind the crown every day.

The crown only needs to be operated to adjust the time and date. Similar to mechanical watches, the crown must be pulled up one notch before adjusting the time and date.
