The Omega Seamaster 300, in its various iterations, is a highly sought-after dive watch known for its robust build, classic design, and impressive performance. Whether you're the proud owner of a vintage Seamaster 300 or a newer model, understanding how to correctly adjust the date is crucial for maintaining its accuracy and longevity. This comprehensive guide will walk you through the process, addressing potential pitfalls and offering additional information on the various Seamaster 300 models available.
The Essential Steps: Adjusting the Date
The date-setting mechanism on most Omega Seamaster 300 models is relatively straightforward. However, there's a crucial time window to avoid when adjusting the date, a precaution that safeguards the watch's internal mechanism. Here’s the step-by-step process:
1. Unscrew the Crown: Locate the crown (the small knob typically positioned at 3 o'clock on the watch case). Most Omega Seamaster 300 models have a screw-down crown designed for water resistance. Unscrew the crown by turning it counterclockwise until it is loose enough to pull out. Do this gently to avoid damaging the threads.
2. Pull the Crown to the Second Position: Once the crown is unscrewed, carefully pull it out to the second position. This is one click past the winding position. You'll feel a distinct resistance as you move it from the first to the second position. The first position (when pulled out only slightly) is used for winding the watch. The second position is dedicated to setting the date.
3. Set the Date: With the crown in the second position, rotate the crown counterclockwise to adjust the date. Each rotation will advance the date by one day. Turn the crown until the correct date is displayed in the date window.
4. Avoid the "Quickset" Danger Zone (8 PM to 2 AM): This is critically important. Avoid attempting to change the date between approximately 8 PM and 2 AM. This is the period when the date mechanism is engaged in preparing for the next day's date change. Attempting to adjust the date during this time can damage the internal components of the watch movement, potentially requiring costly repairs. It's best to wait until outside this window.
5. Push the Crown Back In: Once the date is correctly set, gently push the crown back into its original position. Ensure it's fully seated and screwed down tightly to maintain the watch's water resistance.
