For watch enthusiasts, a wristwatch is an essential item to be worn on every occasion. Whether it’s a party or an adventure, the timepiece must follow its wearer wherever it goes. But what about the time one must go underwater? Is there a durable watch capable of following you down the blue ocean? Yes. A screw down crown watch is the answer.

A screw down crown was originally patented in 1926 by Paul Perregaux and Georges Perret in Switzerland. They found a system in which a crown could be screwed down onto the case, hence creating a waterproof seal. Later in 1927, Mercedes Gleitze tested it by wearing it while swimming in the English Channel.

In general, a screw down crown can be found in any type of watch. But its feature makes it most common in dive watches. So, what is a screw down crown? How exactly does it work in regard to protecting the watch from water? Find out all the information you need to know below!

What is A Screw Down Crown?

A crown may not be an eye-catching feature of a watch, but it is undeniably an important one. Without a crown, the mechanical features like setting up the time and date as well as winding the movement will not work. A screw down crown watch is no exception to this.

Other than setting up time and date, a crown is instrumental in protecting the inside of a watch from dust and water. Unlike the regular crown, the screw down crown is equipped with a seal feature. It helps prevent liquid or any powdery substances from getting into the case.

The key point of a screw down crown watch is its water-resistance qualities. Once the seal shuts, the inside of the watch will be protected against anything from the outside world. In short, a screw down crown watch is a reliable timepiece to accompany you during your time in the water.

How Does A Screw Down Crown Watch Work?

As the name indicates, a screw down crown watch operates using a system in which a crown could be screwed down onto the case to create a seal. Therefore, no water will enter the watch and ruin the inside.

How does a screw down crown watch work then? It uses a simple principle of a screw thread attached to the crown. Winding a screw down crown watch in a counterclockwise direction will allow you to set the date, time, and day. Usually, you just need to pull it once to set the date. Then to set the time, you must pull it one more time.

Then, how does a screw down crown watch work to seal the water? First, you must make sure the stem goes all the way into the case. Afterward, pushing and winding the crown in a clockwise direction should screw it back down. That way, no liquid or dust can go into the inside of the watch.
