Greetings, and welcome to the world of Grand Seiko. Today I'll be your guide to proper usage, care and maintenance of your Grand Seiko SBGJ017 GMT Hi-Beat Automatic. Now it's important to note that though this is an automatic movement, it can be manually wound should it run down. Take the crown in the first position flush to the case and turn it in a clockwise direction approximately 30 turns. Now this will be sufficient to start the beat of the balance and advance the second hand. You can put it on your wrist now and the course of the natural kinetic action on the wrist in conjunction with the case back winding rotor will continue to wind the watch and, over several days of consecutive use, will fully energize the power reserve.

If you wish to fully energize the power reserve by manual winding, simple continue turning the crown. Approximately 45 to 50 turns should be sufficient to fully energize the watch's approximately 55-hour power reserve. You can give it a few extra turns. Because of the bridal-style mainspring engineered into the watch, it simply slips and relieves tension. You cannot accidentally overwind by manual or automatic means.

Once you've wound the watch, there are two separate setting positions for the crown that allow for precise setting. Now the intermediate position between outermost and innermost, which is used for winding, allows you to set the local hour hand. That's the time where you are. That's why, as I advance it, you can see that the date wheel is driven forward. Now the local hour hand can be set forwards or backwards as per your travel through the time zones. You'll note that the second hand continues to advance and though imperceptible, so do the 24-hour reference hand and the minute hand.

When you want to set the watch precisely against a reference time, the outermost crown position stops the second hand or hacks the watch. Now as I set the indications, they all move in sync. This can be used to synchronize to a known accurate reference time such as an atomic clock. Simply stop the second hand at the index of 12 o'clock and then advance the minute hand to the next nearest minute. When the reference time catches up with your watch, push the crown in, resume the beat of the balance. Now you've synchronized your watch to your reference.

Now with respect to care for your watch, there are 3 primary areas of concern: water, magnetism and shock. Now water is foremost. First, it should be announced and you should always mind the fact that leather is never water-resistant. A leather strap is a porous, natural material. Always disuse a leather strap in favor of a textile, rubber or bracelet before taking a watch of whatever water resistance into proximity with moisture. Leather will rapidly degrade when wet.

With respect to actual water resistance, this timepiece is rated to 3-bar or 30 meters. What that means in practical terms, per Grand Seiko, is that the watch is sufficient for everyday water exposure, such as rain, such as splashing as you wash your hands but not for swimming or aquatic activities. As seals age and lubricants dry, water resistance ebbs so always have the water water-tested with an authorized service center of Grand Seiko, minimally every 24 months to ensure that the water resistance is in tact as rated by the factory. It should also be said that magnetism is now ubiquitous in daily life. 

Now with respect to shock, concussive and vibration effects of certain activities can minimally affect the timing precision of your watch and maximally damage the fine mechanical caliber. Disuse the watch during activities such as dirt biking, mountain biking, firearms marksmanship, golf, baseball and tennis as all of these can damage the watch.

Finally, service is a significant factor in the ownership of a fine mechanical timepiece. Grand Seiko recommends minimally every three years having your watch serviced comprehensively by an authorized service center of Grand Seiko. It's important to service exclusively with an authorized center as only these agencies have the original factory replacement parts, specialized equipment and trained personnel to maintain the value of your watch as both an investment and as an instrument. Moreover, only these agencies can back all parts and labor invested with an original factory Grand Seiko service warranty.
