Thank you very much for purchasing the Grand Seiko mechanical watch.

Take hold of your watch softly.

Hear the watch ticking,

tick tock, tick tock, tick tock,

soft and faint, a dignified sound can be heard.

The sound can be called

the crystal of the craftsmen's spirit and skill.

Handpicked parts assembled one by one,

carefully, with craftsmanship,

giving life to a mechanical watch.

This is proven by the sound.

Talking about accuracy,

mechanical watches cannot be compared to

quartz watches, that is for certain.

However, the accuracy of a mechanical watch

is pursued by human hands.

Full of spirit and know-how of craftsmen.

A mechanical watch - complicated, sensitive,

and having a human touch.

We would like to let all of you know

the charm of a mechanical watch, which has no bounds.

So we made this handbook, mainly detailing the accuracy.

Wishing you will have a nice time

with your Grand Seiko for a long, long time.

INTRODUCTION

-About mechanical watch-

We will explain by example

Quartz watches that you have come to be

familiar with.

These are just like airplanes, controlled by

computers.

A battery, IC, and crystal make quartz

watches work accurately, electrically.

Some loss or gain may occur while the

watch is worn.

However, this will be too small to notice in

your daily life.

If a quartz watch resembles an airplane,

a mechanical watch is like a bicycle.

All watch parts work together mechanically

to make it tick.

Thus, a mechanical watch is easily affected

by the outside environment.

If it is hot, the watch tends to lose time.

When power driving the watch becomes

short (when the amount the spring is

wound is short), accuracy becomes

unstable.

If the resting position of the watch is

changed, accuracy is also affected.

The rate of loss/gain could be significant

that you will notice in your daily life.

The measured loss/gain of the watch per day

This is called the daily rate.

The accuracy of a mechanical watch

is usually shown in this daily rate.

The accuracy of a mechanical watch changes

delicately day by day,

depending on the condition in which the watch is used

or the outside environment.

Thus,

By only observing loss/gain in one day,

you cannot judge how accurate the watch works.

If you check the average of the daily loss/gain rate,

you can judge the accuracy of the watch.

In the case of quartz watches, the accuracy is usually

shown by the monthly/yearly rate.

Total losses/gains for a month/year are called the loss/

gain rate of quartz watches.

Quartz watches and mechanical watches - what is the difference?

The accuracy is shown by the daily rate
