Rolex Crown: What to Look For?
Just like any other mechanical watch, the crown on Rolex watches is also used to wind the movement and set the time, date, and other functions of the watch. But apart from doing that, the crown also showcases some important information. And they do it by placing small dots under the Rolex logo on the crown. Having a single dot or multiple dots or even a single line can signify different things. Here’s what each symbol tells you about the watch.
Twinlock System
As explained in the video above, if you see a single line under the Rolex logo, it means that your watch features the Twinlock System. In the case of White Gold watches, the crown will feature Two Dots to depict that the watch has a Twinlock system. Lastly, a Platinum watch will feature a Single Dot ensuring users that their watch features the Twinlock system.
Triplock System
In the case of the watch having a Triplock system, it will feature three dots under the logo on the crown. If the watch is constructed out of White Gold, there will be a big dot surrounded by two small dots. And if the watch is Platinum, it will be a small dot and two big dots under the logo.
| Steel / Yellow Gold | White Gold | Platinum | |
|---|---|---|---|
| Twinlock System | Single Line | Two Dots | Single Dot |
| Triplock System | Three Dots | One Big Dot & Two Small Dots | One Small Dot & Two Big Dots |
Difference Between Twinlock and Triplock Systems
Back in 1953, Rolex introduced the Twinlock winding crown that brought a double seal to the watch making it more water resistant. Later in 1970s, the Swiss watch manufacturer went one step ahead and triple-sealed the watch calling it the Triplock system. In the current lineup, all of Rolex’s dive watches and professional watches including the Daytona, GMT Master II, Submariner, and Yacht Master feature the Triplock system.
Other watch models including the Datejust, Day-Date, Oyster Perpetual and a few other models still use the Twinlock winding crowns.
