Since 2005, Omega has continually honored its maritime legacy with the Seamaster line, and the Seamaster 600-meter model stands as a testament to modern watchmaking. Certified as a Master Chronometer, this timepiece combines innovative design with exceptional precision. Below, we provide a clear, step-by-step guide to adjusting the time and calendar on your Seamaster 600, ensuring you get the most from your investment.

Adjusting the Time on Your Seamaster 600

To set the time, gently pull the crown to the second position (the outermost stop). Rotate the crown clockwise or counterclockwise until the hands display the desired time. For optimal accuracy, we recommend aligning the minute hand with the minute marker after setting.

Important Precautions for Time Adjustment

Avoid changing the time or date between 11:00 PM and 5:00 AM. During these hours, the date-change mechanism is engaged, and manual adjustments could damage the movement. If you need to set the time during this window, first move the hands to a safe time, like 6:30, then proceed.

Winding Your Omega Seamaster

When the crown is in the neutral (pushed-in) position, turning it clockwise winds the mainspring. For a new watch or one that has not been worn for days, wind it about 30 times to build up a power reserve. This helps prevent the watch from stopping or losing accuracy due to inactivity.

Setting the Date on Your Seamaster 600

Pull the crown to the first position (one click out) to adjust the date. Turn the crown clockwise to advance the date through 1 to 31. For months with only 30 days, you will need to manually advance to the 1st of the next month. Note: If you set the date during the day, you may need to rotate the time 12 hours to avoid confusion between AM and PM.

Additional Functions on Chronograph Models

If your Seamaster 600 features a chronograph with subdials, use the pushers on the right side of the case. The upper pusher typically starts and stops the chronograph, while the lower pusher resets it. The 9 o'clock subdial may show the running seconds or a 12-hour totalizer, and the 3 o'clock subdial often tracks minutes or dates, depending on the model. Always refer to your specific reference for exact functions.

Maintenance Tips for Longevity

Regular winding and proper adjustment habits will keep your Seamaster 600 running smoothly. If you notice any resistance when pulling the crown, do not force it—have the watch serviced by a professional. With proper care, your Master Chronometer will remain a reliable companion for years to come.
