■CAUTIONS ON WATER RESISTANCE

CAUTIONS

Do not turn or pull out the crown when the watch is wet.

Water may get inside of the watch.

※ If the inner surface of the glass is clouded with condensation or water droplets appear inside of the watch for a long time, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or SEIKO CUSTMER SERVICE CENTER.

If water-resistant level of your watch is

 

defined as“AIR DIVER’S”

English

WARNING ○ Never use the watch in saturation diving using

helium gas.

 

○While diving, never operate the watch in any other manner than described in this instruction manual.

CAUTION Before using the diver's watch, you have to be properly trained in various types of diving and possess the requisite experience and skill to dive safely. When diving, strictly abide by the rules of diving.

Do not leave moisture, sweat and dirt on the watch for a long time.

Be aware of a risk that a water resistant watch may lessen its water resistant performance because of deterioration of the adhesive on the glass or gasket, or the development of rust on stainless steel.

Do not wear the watch while taking a bath or a sauna.

Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch.

If water-resistant level of your watch is defined as“WATER RESISTANT”

WARNING

Do not use the watch in scuba diving or saturation diving.

The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water-resistant watch with the BAR (barometric pressure) display. For diving, use special watches for diving.

CAUTION

Do not pour running water directly from the faucet.

Precautions for diving

○ Before diving

Inspect the following items before diving.

⇒“NAMES OF THE PARTS”page 13.

①The time is correctly set.

②The power reserve indicator shows the level of remaining power not less than one-half. If the remaining power shows less than one-half, turn the crown to wind the mainspring.

⇒“How to read the power reserve indicator”page 17.

⇒“How to wind the main spring” page 18.

③The rotating bezel turns smoothly. (The bezel rotation must not be too loose or too tight.)

⇒“Unidirectional rotating bezel” page 33.

④The crown is completely screwed in.

⇒“Screw-lock type crown”page 16.

⑤No abnormalities such as flaws or cracks exist on the band or glass.

⑥The band is reliably fixed with spring bars, buckles or other parts.

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.
