The Omega Seamaster 300M is a highly regarded timepiece known for its precision, durability, and elegance. Whether you’re a new owner or a seasoned collector, knowing how to properly adjust the date on your Omega Seamaster 300M is essential. This guide provides a step-by-step explanation on how to do so, ensuring your watch functions accurately and looks its best.
Introduction to the Omega Seamaster 300M
The Omega Seamaster 300M is part of the prestigious Seamaster collection. Known for its professional diving capabilities and exquisite design, this model has been a favorite among watch enthusiasts and professionals alike. It features a robust build, exceptional water resistance, and a reliable automatic movement.
Understanding the Movement
Before adjusting the date, it’s important to understand the movement inside your Omega Seamaster 300M. Most models are equipped with the Omega Co-Axial caliber 8800 or 8806, both of which offer excellent precision and a date function. The movement operates automatically, meaning it is powered by the motion of your wrist.
Tools You Will Need
A clean, soft cloth to lay your watch on.
A watch case opener (if necessary, although not typically needed for date adjustment).
A good light source to ensure you can see the date window clearly.
Step-by-Step Guide to Adjusting the Date
1. Positioning Your Watch
First, ensure your watch is clean and positioned correctly. Lay it on a clean, soft cloth to avoid scratches. Make sure the crown (the small knob on the side of the watch) is easily accessible.
2. Unscrewing the Crown
Many Omega Seamaster 300M models feature a screw-down crown for added water resistance. To unscrew the crown:
Hold the watch firmly.
Gently turn the crown counterclockwise until it pops out to the first position.
3. Pulling the Crown to the Date-Setting Position
The crown has multiple positions:
First Position: Winding position (closest to the watch case).
Second Position: Date-setting position.
Third Position: Time-setting position.
To set the date:
Pull the crown gently to the second position. You will feel a small click.
4. Adjusting the Date
With the crown in the second position, you can now adjust the date:
Turn the crown slowly in a clockwise direction.
Continue turning until the desired date appears in the date window.
5. Ensuring the Correct Time Cycle
It’s important to set the date during the correct time cycle to avoid damaging the movement:
Avoid adjusting the date between 8 PM and 4 AM, as the date-change mechanism is engaged during this period.
If unsure, advance the time past 4 AM before adjusting the date.
6. Pushing the Crown Back In
Once the date is set correctly:
Push the crown back to the first position.
If your model has a screw-down crown, screw it back in by turning it clockwise until it is secure.
7. Double-Checking the Date and Time
After adjusting the date, double-check to ensure the time and date are correct:
Ensure the date is displaying correctly.
Verify that the time is set accurately.

Common Issues and Troubleshooting
Date Not Changing at Midnight
If the date doesn’t change at midnight, it might be set to the PM cycle instead of AM. Adjust the time by 12 hours to fix this.
Crown Feels Stiff
If the crown feels stiff, do not force it. Instead, consult the user manual or contact a professional watchmaker to avoid damaging the movement.
Watch Stopped
If the watch has stopped, it might need winding. Wind it by turning the crown in the first position clockwise for 30-40 turns before adjusting the date.
