CHARACTERISTICS OF A MECHANICAL WATCH

(self-winding type, automatic winding type)

●This mechanical watch operates using power obtained from a mainspring.

●If the watch is completely stopped, manually turn the crown approximately 20 times to wind up the mainspring to start the watch.

●While loss/gain of a quartz watch is indicated by a monthly or annual rate, accuracy of a mechanical watch is normally indicated by a daily rate (loss/gain per day).

●Normal usage accuracy of a mechanical watch varies according to conditions of use (time period that the watch is worn on the wrist, temperature environment, hand movement, and winding state of the mainspring).

●When the watch is affected by strong magnetism, it temporarily gains or loses time. If the watch encounters a strong magnetic field, the parts of the watch may be magnetized. In this case, repairs such as removal of magnetism are required. Contact the retailer from whom the watch was purchased.

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.
