Crowns – What You Should Know

539_3Every watch has a crown, and they all come in different shapes and sizes. Its appearance is largely aesthetic; some watches come with a standard knurl-edged crown, while others have a pumpkin or onion shape. It is important to understand that the crown itself has many important functions outside of setting the time. For example, diver’s watches have crowns built structurally closer to the case to provide better water resistance.

Push/Pull – This is the most basic type of crown. Pull the crown out to set the time, push it back in to resume normal function. More advanced movements might have a “hacking” function, which stops the seconds hand when the crown is pulled out. This allows for better time synchronization and accuracy. Many movements also have more than one “position”, allowing you to set various functions depending on how far the crown is pulled out.

Screw Down – This type of crown is typically found on diver watches. In addition to a push/pull function, the crown can be screwed down and tighted to create a water resistant seal between the crown stem and the case. This confers superior resistance against potential water damage.

Note: When you’re dealing with quick set dates, be sure to always set the time to 4:00 before using the date complication. This prevents potential damage done to the movement.
