English

* There is no need to turn the crown further when the mainspring is fully wound. But

the crown can be turned without damaging the watch mechanism.

 

* Once the watch is wound up fully, it operates for about 50 hours. However, when the stopwatch is used continuously for a certain period, the watch may not operate for as long as 50 hours.

* If the watch is used without being wound up fully, gain or loss of the watch may result. To avoid this, wear the watch for more than 8 hours a day. If the watch is used without being worn on the wrist (if it is used on the desk like a clock, for example), make sure to wind it up fully every day at a fixed time.

* If the watch has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. This is because the mainspring torque (force) is low at the beginning of its winding due to the characteristics of mechanical watches. The small second hand starts to move when a certain degree of strong torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to forcibly turn the balance can start the watch sooner.

HOW TO SET THE TIME AND DATE

•

Check that the watch is operating, and then set the time and date.

English

 

•

The watch is provided with a date function and is designed so that the date

 

 

changes once every 24 hours. The date changes around 12 o’clock midnight. If

 

 

AM/PM is not properly set, the date will change around 12 o’clock noon.

 

1. Pull out the crown to the first click. (The small second hand continues moving and the accuracy of the watch is unimpaired.)

2. The date can be set by turning the crown clockwise. Turn it until the previous day’s date appears.

Ex.)If today is the 6th of the month, first set the date to ”5” by turning the crown clockwise.

CAUTION

•Do not set the date between 8:00 p.m. and 2:00 a.m. If you do so, the date may not change properly on the following day or malfunction of the watch may occur.

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.
