What is the crown of a watch?

      A watch crown is the little knob us on the side of the watch to set time.Other functions can be provided depending on the watch.  The mainspring of a mechanical watch.  The crown is the command center of the watch.

  The crown of watch is usually at the three oclock position.Also known as a winding crown or crown wheel, it is used to wind the watch’s mainspring, adjust the time or date, and regulate the watch’s functions.That’s what is the crown on a watch. The crown is connected to the watch movement through a stem or spindle and controls the watch’s internal parts by turning it in a clockwise or counterclockwise direction. It is an essential part of a  watch, and without it, the watch would be difficult to operate and maintain.that’s what is the crown on a watch.

Brief history of the watch crown

  The crown on watch has come a long way since its origins in the 16th century.  Early pocket watches were wound through a small square, but watchmakers later added winding stems with keys.  Women’s wristwatches had pin-set knobs, which were replaced by screw-down crowns in the 1920s.  Today, there are many kinds of crown of a watch, from push-pull to screw-lock, and some can adjust various watch functions.  The evolution of the watch crown has enhanced the convenience, protection, and functionality of timepieces while improving their aesthetic appeal.

  The reason why it is called a crown is because the term has royal inspiration,as the round,fluted shape of the winding knob reminded the crowns from European royalty.then the namecrown stuck.

The Function of The Watch Crown 

 Watch Crown is a crucial component of a watch that enables many important watch functions.  The four Functions of the Watch Crown are:

.Setting the time

    You can adjust hours and minutes by rotating the crown on a watch and ensure that the time is accurate.  Some watches also allow you to adjust the date by rotating the crown.  Make sure to turn the crown on watch counterclockwise until it stops and then turn it clockwise to set the time accurately. 

.Winding the watch

       Automatic mechanical watches need to be manually wound to maintain accurate time. You can rotate the crown as needed to transfer energy to the mainspring. Manual mechanical watches also need to be wound, but require more frequent winding.  

.Changing the date or other functions

      If your watch has multiple functions, use the crown to switch between functions or adjust the date.  Each brand and model has different ways of doing this, so check the watch manual for more information.  


      Some watches are water-resistant, and the crown ensures that the watch’s water-resistance function is working correctly.  If you plan to immerse the watch in water, tighten the crown to maintain water resistance. To maintain the watch’s water resistance performance, ensure that you send it to a professional watch repairer for inspection and replace the gaskets every year. 

Watch crown types

.Conical Crown

    This type of crown is usually small and cone-shaped, often found on manual mechanical movements. The appearance of these crowns is usually sleek and modern.

.Screw-down crown

     This type of crown has a threaded design to provide better water resistance.  These crowns are screwed into the watch to create an effective water seal.

    Rolex didn’t invent the concept of the spun-off crown, but Rolex first used it in the Oyster case in 1926 .

    Available in diving watches, a screw down crown is a special feature which aids in water resistance. This type of threaded winding crown screws tightly into the case and protects the case from any form of dust and water.

.Push-pull crown

  Also known as standard crowns, these crowns are easy to operate and have a relatively simple design, making them ideal for everyday wear.

    Pull/push crowns securely seal the watch to more than 200 meters, so they are no less waterproof than tight-knit crowns.  Conversely, the threads don’t wear out, which means the pull/push crown will theoretically remain waterproof for longer than the screw down crown. 

Onion crown

.Onion crown

This type of crown has a shape similar to that of an onion.  They are usually larger and more prominent, making them easy to use. Onion crowns can be found on manual mechanical watches and some automatic mechanical watches. 

.Crowns with Cabochon

  These crowns are often paired with gemstones or other luxurious decorations, giving them a very luxurious appearance. These crowns can be used on quartz watches and some automatic mechanical watches.

.Push-Button Crown

    The Push-Button Watch Crown is a button style crown on a watch used to adjust the time, date or other functions by easily rotating the crown through pressing the button. It is typically used in chronograph watches to control timing functions like start, stop, reset, and more for calculating speed, distance, time intervals, etc.

.Straight Crown

This type of crown is the simplest design, being straight or rectangular when perpendicular to the watch case. These crowns often have a sleek and clean appearance, making them ideal for everyday wear.

Watch Crown Maintenance and Care

     Watch crown maintenance and care is crucial to ensuring the longevity and functionality of your watch crown.There are three main aspects of watch crown maintenance and care: cleaning and polishing, lubrication, and replacement. 

.Cleaning and Polishing

   The watch crown should be cleaned regularly to prevent dirt and debris from clogging it, which can result in damage to the mechanism.  This can be done by wiping it with a soft cloth or a toothbrush dipped in warm soapy water, being careful not to submerge the watch or get water inside it. For stubborn dirt, a specialized watch cleaning solution may be used. Polishing can also be done to restore its shine, but care should be taken to avoid scratching the watch crown’s surface or removing any plating.


   Watch crowns need to be regularly lubricated to ensure they are working properly. To lubricate the crown, a watchmaker will carefully remove the winding stem and apply a small amount of specialized oil to the gears and mechanism inside the watch crown. This process should only be performed by a professional watchmaker.


   In some cases, the watch crown may need to be replaced if it becomes damaged or worn beyond repair.  This involves removing the old crown and replacing it with a new one that matches the style and material of the original. This should also be performed by a professional watchmaker. 

Proper watch crown maintenance and care will help ensure the longevity and accuracy of your watch, as well as keep it looking its best.  

Conclusion-what's the crown of a watch

In conclusion, the watch crown is a small yet essential component of a wristwatch.  It serves several vital functions, including setting the time, changing the date, winding the watch, and adjusting other functions on the watch.  With proper maintenance and care, including regular cleaning and lubrication and timely replacement if necessary, the watch crown can continue to perform its functions efficiently for a long time.  Adequate maintenance and repair should always be performed by a professional watchmaker to maintain the essential characteristics of the watch crown.  Overall, the watch crown plays a crucial role not only in the timekeeping accuracy of the watch but also in enhancing the aesthetic appeal of the timepiece.
