Magnetic resistance
（Magnetic influence）
・Grand Seiko mechanical watches conform to the Magnetic Resistance Standard* of JIS
Class 1, and the mechanical watch has magnetic resistance to maintain performance in
most cases even where it is brought close to （at least 5cm spaced from） equipment
generating a magnetic field in normal life. However, the movement part is magnetized
when it encounters a strong magnetic field, thereby accuracy may go out of order. Pay
attention so as not to bring the watch close to equipment （health appliances, speakers,
and mobile phones using a magnet） generating a strong magnetic field within 5cm.
・If the accuracy exceeds the accuracy target range （-1 to +8 seconds/day） during
normal usage due to magnetization, removal of magnetism and accuracy readjustment
works are charged regardless of the guarantee period.
＊JIS Antimagnetic Standard Class 1 means standard class 1 specified by JIS B 7024
（Antimagnetic watches - Classification and Performance）, which is an antimagnetic
standard tolerable to a DC field of 4800A/m.

Examples of common magnetic products that may affect watches
M e t a l l i c b a n d
Band
○
Moisture, sweat or soil will form rust even on a stainless steel band if they are left for a long time.
○
Lack of care may cause yellowish or gold stain on the lower sleeve edge of shirts.
○
Wipe off moisture, sweat or soil with a soft cloth as soon as possible
○
To clean up the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush.
（Protect the watch body from water splash by wrapping it up with plastic wrap etc.）
○ Because some titan bracelets use pins made of stainless steel, which has
outstanding strength, rust may form in the stainless steel parts.
○
If rust advances, pins may poke out or drop out, and the watch case may fall
off the bracelet, or the clasp may not open.
○
If a pin is poking out, personal injury may result. In such a case, refrain from
using the watch and request repair.
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of
care may accelerate deterioration of the band or cause skin fit or stain on the sleeve edge.
The watch requires a lot of attention for a long usage.

○
Leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
○
Wipe moisture and sweat dry as soon as possible by gently blotting them up with a dry cloth.
○
Do not leave the band under direct sunlight.
○
Be careful to use a light-colored band because stains are highly visible.
○ Refrain from wearing a leather band watch while bathing, swimming, and when working with
water even if the watch itself is water-resistant enforced for daily use （10-BAR water resistant）.

Notes on skin fit
and allergy
Skin fit caused by band has various reasons such as allergy to
metals or leathers, or skin reactions against rubs on dust or the
band itself.
Notes on the length
of the band
Adjust the band with a little clearance with your wrist to ensure
proper airflow. Make a room for one finger around your wrist
when you wear the watch.
