Rolex is committed to excellence not only in design and craftsmanship but also in maintaining rigorous quality control standards. With state-of-the-art workshops and manufacturing facilities, Rolex takes every measure to ensure that each watch that leaves their factory meets the brand’s high standards for performance, durability, and elegance. Here’s an inside look at the quality control process and the unique facilities where Rolex watches are made.

The Rolex Quality Control Process

Rolex watches undergo an extensive testing process designed to catch even the smallest flaws. By rigorously testing every aspect of their watches, Rolex can guarantee reliability, longevity, and precision for each piece.

1. Material Quality Control

Rolex’s commitment to quality starts with the materials. Every batch of 904L Oystersteel, gold, and platinum undergoes inspection to verify purity and consistency.

• Meticulous Checks: Every metal is tested to ensure it meets Rolex’s high standards.
• Consistency Across Watches: Rolex aims for uniformity, ensuring that each watch, regardless of its model, has the same shine, texture, and resilience.

2. Waterproof Testing

The iconic Oyster case is tested for water resistance by submerging it in pressurized tanks. Watches are tested at varying pressures, including depths far greater than those stated in their specifications, to ensure they exceed the stated limits.

• Pressure Chambers: Watches are tested at high pressures to confirm waterproofing, ensuring models like the Submariner can withstand depths of up to 300 meters or more.
• Thermal Testing: Rolex also performs thermal shock tests by heating and cooling watches rapidly, checking for any potential structural issues.

3. Chronometer Certification

Each Rolex movement is certified as a Swiss chronometer, which requires passing tests for accuracy. Rolex conducts its own additional testing after the official certification, further ensuring reliability.

• COSC Certification: All Rolex movements are COSC certified, which requires each movement to stay within -4/+6 seconds per day.
• Superlative Chronometer Certification: Rolex conducts additional tests beyond COSC standards, achieving a precision rate of -2/+2 seconds per day.

4. Stress and Durability Testing

Rolex watches are known for their durability, and to maintain this reputation, each model undergoes extensive stress testing. Watches are exposed to simulated environments, including vibrations, extreme temperatures, and magnetic fields.

• Shock Testing: Simulating impacts that watches may experience during daily wear, Rolex ensures durability without compromising function.
• Magnetic Resistance: Rolex tests resistance to magnetic fields, crucial for ensuring accuracy in the modern world filled with electronic devices.
