"HOW TO USE"

This watch is an automatic watch equipped with a manual winding mechanism.

When the watch is worn on the wrist, the motion of the wearer's arm winds the mainspring of the watch.

If your watch is completely stopped, it is recommended that you manually wind the mainspring by turning the crown.

How to manually wind the mainspring by turning the crown

1. Slowly turn the crown clock wise (in the 12 o’clock direction) to wind the mainspring.

* Turning the crown counterclockwise (the 6 o’clock direction) does not wind the mainspring.

English

*If your watch has a screw-lock crown, the crown will screw into the watch case for added protection.

After completing all settings of the watch, screw the crown in again by turning it clockwise while pressing it.

If the crown is too stiff to be screwed in, turn the crown counterclockwise once and then give another try.

Do not screw it in by force as it may damage the slots of the crown.

2. Continue to turn the crown until the mainspring is sufficiently wound. The small second hand will start moving.

3.Set the time and date before putting the watch on your wrist.

6S28 specifications

Seiko Group's 6S28 movement is an exemplary piece of horological engineering that showcases the brand's commitment to precision and innovation. This automatic movement is primarily known for its use in some of Seiko's popular watches, combining both traditional craftsmanship and modern technology.

One of the defining features of the 6S28 movement is its robustness. With a frequency of 28,800 vibrations per hour, it ensures a high level of accuracy, making it a reliable choice for enthusiasts and everyday wearers alike. This frequency, standard for many of Seiko’s higher-end movements, allows for a smoother sweep of the second hand, which is not only visually appealing but also enhances timekeeping precision.

The 6S28 movement boasts a power reserve of approximately 45 hours, providing ample time between winding sessions. This is particularly advantageous for users who may not wear their watches daily, allowing the timepiece to remain operational without requiring frequent winding. Additionally, the movement incorporates a hacking mechanism, enabling users to set the time with precise accuracy by stopping the second hand when adjusting the hour and minute hands.

A key technological highlight of the 6S28 is its use of Seiko's proprietary escapement design, which minimizes friction and enhances durability. This allows the movement to be less susceptible to wear and tear, prolonging the life of the watch. Furthermore, the 6S28 features a date complication, conveniently positioned for easy readability, enhancing its practical use for daily wear.

Another notable characteristic of the 6S28 is its anti-magnetic properties. This is particularly important for a modern watch, as magnetic fields are omnipresent in today’s environment and can adversely affect timekeeping precision. The inclusion of anti-magnetic materials within the movement adds a layer of reliability that is appreciated by both watch collectors and casual wearers.

In terms of design, the 6S28 movement is elegantly finished, with various details that reflect Seiko's dedication to aesthetic value. The movement is often visible through transparent case backs, allowing wearers to appreciate the intricate workings of the mechanism.

Overall, the Seiko Group's 6S28 movement merges functionality with craftsmanship in a way that meets the high standards of modern horology. Its blend of advanced technology, reliability, and aesthetics makes it a sought-after choice for watch enthusiasts seeking a timepiece that embodies both heritage and innovation.
