Overview
This segment explains the Rolex Crown system, focusing on its water protection features and the meaning of various crown markings based on watch materials.
Rolex Crown System Overview
- Rolex Crown systems are designed to protect watches from water damage.
- Rolex typically uses a Twinlock or Triplock system instead of a single lock system.
Twinlock System Markings
- Twinlock crowns feature different marks based on the material: a single dot, double dot, or single line (dash).
- A single dot indicates the watch is made of platinum.
- Two dots mean the watch is made of gold.
- A single line (dash) signifies that the watch is two-tone.
Triplock System Markings
- Triplock crowns always display three dots below the Rolex logo.
- The size and arrangement of the dots indicate the watch material.
- For platinum, the center dot is small.
- For white gold, the center dot is large.
- For two-tone watches, all three dots are the same size, as seen in the Rolex Daytona.
