⑤Upon completion of setting, make sure that the time indicated is correct, and then push the crown back in. The calendar setting is now completed. Relock the crown.

⇒ "How to use the screw-lock type crown" page 16.

※The calendar is designed to work in conjunction with the movement of the hour hand, therefore, if AM/PM is incorrectly set, the calendar will be off by 12 hours.

※The crown can be turned in either direction to adjust the date, however, it is recommended to turn the crown in the direction which enables you to set the date with a smaller adjustment.

※Turn the crown slowly, checking that the hour hand moves in one-hour increments.

※When adjusting the hour hand, the other hands may move slightly. However, this is not a malfunction.

Tips for more accurate time setting

To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.

①Before setting the time, make sure to wind the mainspring sufficiently. (Ensure that the power reserve indicator is showing a full-wound state.)

②When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the second hand (or the small second hand) starts moving, then pull the crown out to the second click.

③The second hand (or the small second hand) will stop moving when the crown is pulled out to the second click. Do not stop the movement of the second hand (or the small second hand) for longer than 30 minutes. If the stoppage of the second-hand (or the small-second-hand) movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the second hand (or the small second hand) restarts moving, and then set the time.

④If you set the time when the time the watch indicates is between 9:00 p.m. and 1:00 a.m., set the hour hand back to 8:00 p.m. temporarily, and then set the time. (This procedure is required to ensure the proper engagement of the calendar driving wheels.)

Time difference adjustment function

For example, while traveling abroad and staying in a place with a different time from where you live, you can conveniently set the watch to indicate the local time in the different time zone area without stopping the watch.

The hour hand indicates the time of the place where you currently are, while the 24-hour hand indicates the time of the place of origin.

The calendar works in conjunction with the movement of the hour hand. If the time difference is correctly adjusted, the watch displays the correct date of the place where you are staying.

How to use the time difference adjustment function

①Make sure that the mainspring is sufficiently wound and the watch is working.

9R15, 9R65 specifications

The Seiko 9R series is a remarkable line of mechanical watches featuring Spring Drive technology, a hallmark of precision and innovation. Among its esteemed models, the 9R65 and 9R15 movements stand out for their unique characteristics and advancements.

The 9R65 movement is known for its impressive power reserve of up to 72 hours, which is significant for a watch powered by a spring-driven mechanism. This makes it extremely reliable for everyday wear, as users can take the watch off for a weekend without worrying about it stopping. One of the most notable features of the 9R65 is its smooth and continuous movement of the second hand, a signature of Spring Drive technology. Instead of ticking like traditional mechanical watches, the 9R65 provides a seamless glide, offering a visual experience that is both captivating and elegant.

On the other hand, the 9R15 movement, while sharing some similarities with the 9R65, takes the craftsmanship a step further with its chronograph function. This feature allows users to accurately measure elapsed time, making it ideal for sports enthusiasts and those who require precision timing. The 9R15 has a power reserve of approximately 60 hours, ensuring that it maintains its functionality over an extended period. Its robust design is complemented by the familiar Spring Drive mechanism, ensuring that while it offers additional functionality, it does not compromise on the smoothness and reliability typical of Seiko.

Both movements utilize Seiko’s advanced Spring Drive technology, which combines the best elements of mechanical and quartz watchmaking. This unique hybrid system allows for unparalleled accuracy, with variations of just one second per day, which is exceptional for a mechanical watch. Furthermore, the 9R series features a durable construction, incorporating high-quality materials such as stainless steel and ceramic, enhancing their longevity and resistance to wear.

In conclusion, the Seiko 9R65 and 9R15 movements exemplify the brand’s commitment to innovation, precision, and durability. Whether you prefer the minimalist elegance of the 9R65 or the added complexity of the chronograph in the 9R15, both options promise an exceptional blend of technology and artistry that showcases Seiko's prowess in horology. These movements not only cater to the demands of modern watch enthusiasts but also pay homage to the intricate traditions of watchmaking, making them a desirable choice for collectors and aficionados alike.
