Hello everyone! Today we at want to talk to you about an important aspect of the watch. The component we're going to explain to you is the watch crown.


The watch crown represents its regulator body, through the crown it is possible to adjust the time, the date or recharge the movement of the Watch.
What is the crown of the watch for?

The Crown is present in automatic, mechanical or manual movement watches and is often adorned with the brand of the manufacturer.
In the diver's watches the crown plays a very important role, so much so that it comes with a protective gasket. In addition, underwater watches always have a crown with a screw closure.

The crown of the Replica Watches Australia is usually placed at three o'clock, in some timepieces, however, for design choices The Crown can also be placed at four o'clock and be equipped with a tight valve protect corona.

The importance of the watch crown for the purpose of waterproofing
As we have already stated it is very important for divers watches to have a crown that can make the watch case more waterproof.

To preserve the other openings in the case such as glass and caseback, the hole in the crown axle must be properly waterproofed.

However, a simple gasket is not enough to obtain the right waterproofing of the watch crown and consequently of the watch itself. The traditional crown pressure closure in fact does not allow guarantees regarding some unpleasant drawbacks such as wear and tear due to prolonged use, friction or external infiltration.

The first company that was able to overcome this problem was Rolex, which in 1926 invented and patented the screw tightening system of the crown Replica Panerai. Thanks to the screw tightening invented by Rolex it was possible to finally dedicate to the first creations of underwater watchmaking.
The patent of the screw-down crown was held long by the Swiss Maison, which could for a long time have a real monopoly of the crown screw-lock watch, ideal for the creation of underwater watches.
The screw fixing of the Crown is still today an essential figure for the realization of a diver's watch. This system involves the use of a threaded tube placed internally or externally, which protrudes from the case and enlarges an identical thread that is made either in the crown or on the axle of the crown. This thread is screwed onto the tube and prevents water seepage.


To protect the watch crown, in addition to this ingenious screw fixing, there are also the so-called parapets. The parapets are nothing more than a system of sealing gaskets that are responsible for increasing the degree of waterproofness of the watch, thus allowing an airtight closure.


The parapets can be either protruding from the case or reentrant, these also allow to protect the crown from any shock.


The watch crown however can make the watch waterproof even without the screw tightening. This is possible thanks to the patent of 1956 registered by Panerai.
