Something you don't know about Omega Co-axial

Introduction

In this tutorial, we will explore the Omega Co-Axial system, particularly through the lens of the Seamaster 150 series watch. We will disassemble the 8500 movement and delve into the mechanics of the Co-Axial movement, highlighting its advantages and principles. By the end, you will have a comprehensive understanding of this innovative watch technology.

Step 1: Understanding the Co-Axial Escapement

• The Co-Axial escapement was developed to reduce friction between components, which enhances the movement's longevity and accuracy.

Key benefits include

• Greater accuracy over time
• Reduced maintenance needs
• Improved resistance to shocks and vibrations

Practical Tip

Familiarize yourself with traditional escapements to better appreciate the Co-Axial system's advancements.

Step 2: Disassembling the 8500 Movement

Gather necessary tools

• Watchmaker's screwdriver set
• Tweezers
• Loupe or magnifying glass

Follow these careful steps for disassembly

1. Remove the case back using a case knife.
2. Unscrew the movement holder.
3. Gently lift the movement out of the case.
4. Remove any visible screws and components, such as the rotor.

Common Pitfall

Be cautious not to apply too much force when removing parts, as this can damage delicate components.

Step 3: Examining the Co-Axial Components

Identify the three main components of the Co-Axial escapement

1. Co-Axial escape wheel
2. Co-Axial pallet fork
3. Balance wheel
• Discuss how these components interact to offer a smoother operation and better timekeeping.

Step 4: Reassembling the Movement

Carefully reverse the disassembly steps

1. Position the balance wheel and pallet fork.
2. Secure the escape wheel in place.
3. Reattach the movement holder and case back.
• Check for proper functionality by winding the watch and observing the movement.

Practical Tip

Before reassembling, ensure all parts are clean and free from dust or oils to maintain optimal performance.

Conclusion

In this tutorial, we explored the Omega Co-Axial system and disassembled the 8500 movement of the Seamaster 150 series watch. We highlighted the benefits of the Co-Axial escapement and provided a step-by-step guide for disassembly and reassembly. Understanding this technology not only enhances your appreciation for Omega watches but also equips you with the skills to service them effectively.
