Most people think of a watch crown as something that is only used to change the time, however it can do several other very important functions on a wristwatch or pocket watch. A watch crown is used to wind some watches (manual wind mechanical watches); it can stop the watch (by pulling it out) and make you battery last longer when you are not using the watch. The traditional watch crown is used for these four functions;

 

  • Change the time
  • Set the date and day
  • Wind the watch
  • Stop the watch

What does a watch crown do?

We already told you the most common uses of a watch crown but there are other types of watch crowns that are for stop watch functions (usually with chronograph watch crowns) along with moon phase, time zone, and count down timer features. The crown is attached to a watch stem that protrudes into the watch movement allowing you to mechanically make manual changes to the watch including electronics and mechanical motions. Sometimes a watch button can look like a crown – the main difference is that a buttons only feature is pushing in for desired feature.

 

Watch Crown Wear

Watch crowns are usually made of metal or stainless steel and are designed to be tough for everyday wear. On some watch brands, the watch crown is protected by metal that sticks out on the watch case but other watches leave the watch crown more open to the possibility of catching, bending, and breaking. There can be several parts included in a watch crown like a small gasket, metal threading, and sleeves designed to protect the inside of the watch from moisture and debris. If your watch crown has been subject to chemicals and bending or heavy hitting, you should carefully inspect the crown for any damage to the components and replace a watch crown if necessary.

 

Replacing a Watch Crown

This can be an easy task, but you will usually need some tools to first open a watch back. Sometimes when you replace the watch crown, you will also have to replace the watch stem if the watch crown has been bent or severed completely from the watch. You will also need some tools to remove, cut, and file the watch stem and some glue to attach the stem to the crown.

 

Watch Crown Design

Watch crowns can be simple and plain, they can be adorned with jewels, and silver and gold watch crowns are not unusual. Most watch crowns have ridges to help you grip them in your fingers but some are made smooth and shiny. Some watch crowns are very small coinciding with a smaller watch design while other watch crowns are so big that they are considered “oversized”. The color of the watch crown will usually match the color of the watch case (silver and gold being the most common) but some watch crowns are made in a variety of colors to match the fashion of the timepiece.
