For lifelong use of your mechanical watch rule No.3
Accuracy will vary depending on the temperature.
A piece of metal of about 0.1 mm, as thin as a hair,
is wound.
That is the key that controls the accuracy of all
mechanical watches.
<<Balancing

Balance
spring
Metals expand and contract depending on the
temperature.
This characteristic of all metals also applies to the
balance spring.
This affects the accuracy of a mechanical watch.
In other words,
When it is hot, the balance spring expands and
the watch tends to lose.
When it is cold, the balance spring contracts and
the watch tends to gain. This is typical.
For lifelong use of your mechanical watch rule No.4
Keep your mechanical watch away from magnetic objects.
After you take off your watch,
do you leave it by your cell phone?
Or put it on a television or next to your PC?
Do you put it in your bag with your cell phone?
Watches do not like magnetism.
They may lose or gain when affected by magnetism.
To make your mechanical watch work more accurately,
it is important not to leave the watch close to magnetic objects for a long time.
In particular, cell phones, televisions and speakers of PCs have strong magnetism.
A magnetic necklace, a clasp of a handbag, magnetic parts of refrigerators,
there are many magnetic objects around us.
Please be careful.

For lifelong use of your mechanical watch rule No.5
Do not give your mechanical watch a strong shock.
When you play golf, tennis or baseball.
When you play a sport that gives your arm a strong
impact.
Please take off your mechanical watch.
There are reasons for this.
For instance,
at the moment you hit a golf ball with a club,
the impact of the ball against the club is about 1
ton.
The impact is given to your wrist,
and this will affect very small parts inside your
mechanical watch.
Sometimes, the impact will deform or break a
watch part.
“Good shot” for you becomes “bad shock” for your
watch.

Overhaul, once every three to four years
Love your watch, once every three to four years.
Talk about an overhaul.
In the case of a mechanical watch, there is no
need to change the battery.
However,
maintenance of your watch is also necessary.
Once every three to four years,
please take your watch to our service center for
examining and cleaning every part of your watch.
Once you start using it,
your watch never takes a rest.
And in the case of a mechanical watch, power
given to its gear is stronger,
compared to a quartz watch.
So parts may wear,
oil may dry or be insufficient in some parts.
Especially,
the first three to four years after you start using
your watch is the period when each part gets used
to one another,
and contacting each other causes additional
metal powder.
The first overhaul is
the key to the life of your mechanical watch.
Please keep in mind
an overhaul, once every three to four years
can be considered
love for your watch.
