For lifelong use of your mechanical watch rule No.1
Wind the mainspring of your mechanical watch at a fixed time.
For lifelong use of your mechanical watch rule No.2
Place your watch correctly, like this.
Half of one day, twenty-four hours, when you do not wear your watch. The accuracy while you do not wear the watch is included in “normal usage accuracy”.
The mechanical watch that you take off.
Which position should the watch be put in?
The loss/gain of a mechanical watch depends on the resting position of the watch.
In one position, the watch tends to gain, in another position, it doesn’t.
For instance, while you are sleeping at night, when you do not wear your watch, put the watch in various positions for seven to eight hours, such as placing it with its face turned up, or with the crown up, to find the best resting position for the watch for reducing the loss/gain that occurs while you are wearing your watch.

Accuracy will vary depending on the temperature.
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.
