For lifelong use of your mechanical watch

For lifelong use of your mechanical watch rule No.1

Wind the mainspring of your mechanical watch at a fixed time.

As there are rules for everything, there is a rule for winding the spring.

 

You have not heard this before?

Please keep it in mind.

 

The mainspring - the source of energy for a mechanical watch.

When it is fully wound, it can supply the most stable energy to every part of the watch movement, and the accuracy of the watch becomes most stable.

Even if your watch is a self-winding type, when you feel the accuracy is not stable, turn the crown to wind the mainspring further.

If you work at a desk, etc., and do not move enough, the spring will not be wound sufficiently.

If your watch is a hand-winding mechanical type, turn the crown every day, at a fixed time to wind the mainspring sufficiently.

 

To use the watch with better accuracy, wind the mainspring every day, at a fixed time.
Please keep to this rule as best as possible.

 

For instance, You may make it a rule to wind the spring When you wake up, or at lunchtime.

For lifelong use of your mechanical watch rule No.2

Place your watch correctly, like this.

3 o’clock

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.

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 wheel>>

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.

For lifelong use of your mechanical watch rule No.6

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.
