9S56 This watch, Cal.9S56, features a time difference adjustment function. Two different time zones can be displayed at the same time when you set the hour hand and 24-hour hand respectively in accordance with each time zone. It is a time difference adjustment function to show the times of two areas where there is a time difference in between, such as London and Tokyo.

How mechanical watches work Mechanical watches are self-sufficient. A quartz watch obtains power from a battery. And its accuracy is raised by crystal and IC. On the other hand, a mechanical watch Small movements work together to keep is run by a mainspring. Small metal parts of the watch work togeth- the watch ticking.

The accuracy of mechanical watches The accuracy of mechanical watches is The loss/gain of quartz watches is shown by yearly or monthly r a t e , s u c h a s 1 0 s e c o n d s / y e a r o r 1 5 s e c o n d s / m o n t h .

Thus the figures showing the accuracy of the watch will be different when it is actually worn. The accuracy of Grand Seiko watch should be from -1 seconds/day to +10 sec- onds/day while it is in use. If the average of the daily rates exceeds this level even if the watch is being used in usual life pat- terns, the watch will be adjusted by us.

The elements which affect accuracy Amount the mainspring is wound up Wind the mainspring up fully to In case of mechanical watches, it is important that sufficient energy is supplied to each movement by the mainspring of the watch. If stabilize the accuracy the spring gets unwound and supplied energy becomes less, the parts controlling the accuracy become easily affected by outside...

The elements which affect accuracy Temperature When it is hot, the watch loses time generally. The parts that consist a mechanical watch are made of metals. As you know, metals expand or contract depending on temperatures. When it is cold, The parts that controls the accuracy of the watch expands and the watch gains time generally.
