It is rare, and cost performance is high
Mechanical (belonging to a self-winding watch, rolling by hand) mechanical watch

Including a smartphone, the thing in our surroundings uses all electricity now.
However, "the mechanical watch" does not change the mechanism at all until today after it is invented in 1770 when there was not electricity. In other words, I can say "the only gadget which works without using the electricity".
It is an established theory that there cannot be the perpetuum mobile (the machine which continues working without an energy source permanently) in the world, but in a sense it may be said that the mechanical watch is a miraculous machine achieving this.
Only using the power that a spring comes loose, it ticks away time using a temp and the speed regulator posture such as the ankle in it definitely for one second for one second. And I say many times, but do not use electricity and the IC. The mechanical watch which ancient people beat their brains saying "I want to know time exactly" and had as crystallization of the effort. As camera back is a skeleton, as for this model, you can see the mechanism to tick away time like a heartthrob. Do you not feel the romance from the ancient times?
Unlike a quartz type, the machine type changes smoothly so that a hand slips over a clockface. Sweep handling of a needle means this. This is charm of the mechanical clock, too.
As our model is with rolling by hand, please roll up Lew by all means when you move the clock which stopped. A spring rolls up, and attachment begins to change, and energy is transmitted through the ring line from a car most, and the second hand begins to perform a sweep. I think that you can also enjoy the holy work as if you record a life on a clock.

SEIKO quality

I can wear it comfortably, and "thymeless comfort" is the new constant seller mechanical watch of the ON/OFF combined use to constitute an authentic style not to depend on the times at 2 lines of the classical music line which added a universal "dress line" and a trendy vintage taste to a base.
Quality of SEIKO which is マニュファクチュールウオッチメーカー on behalf of Japan proud to the world. All the exterior is settled for the mechanical movement in SEIKO, too.
This model is limited to stores. It becomes the special model to be able to buy only at neel and an other 1 store.
With high cost performance to be under 50,000 yen, it is very recommended as entry model of the mechanical watch while being a high quality.

See-through skeleton back lid

The camera back made a skeleton to be able to enjoy the movement of a temp and the ankle. By accurate movement, please see a state to tick away time surely finely.
When りゅうずを turns a stopping clock and rolls up a spring, I want to have you perform it while looking at a movement by all means. A clock begins to work by turning りゅうずを as if a life was totally recorded.
I want you to feel joy to own a mechanical clock by all means.
It is everyday life reinforcement waterproofing (10 standard atmosphere) of the relief.

The design which stands out

Mirror side finish from to the case line which is beautiful to drift, form, rag without waste. It is the clock which is beautiful so as to be enchanted just to look. I adopted the design which followed a case, the traditional shape of the SEIKO mechanical model. The Lew guard who is easy to do case size (case diameter 40mm), rolling by hand to be, and not to interfere on the cuffs of the suit well either that are an arm, and prevents bold large crown, malfunction is with it.

The classic line adopted Lumi blight being aware of a vintage taste and secured the night visibility.
The needle was particular about the shape that it was easy to greatly see to show an effect of the Lumi blight to the maximum at the time.

It is a stainless steel pure bracelet let alone a band. I adopt an expensive design of the good 20-16 millimeters tapered feel of a material of a feeling of wearing with lightness. Owner is adjustable by yourself; is an adjust band easily. Certainty, both safe pushes type three compromise, and they are Nakatome. The three-dimensional end peace along the case shape individualizes beauty.

セイコー メカニカル
Hoist of the spring

I turn the spring of the mechanical clock りゅうずを around 40-50 times to completely roll it up. (りゅうず 1 round means that 360 degrees turns.) It works for approximately 41 hours if in condition that a spring is completely rolled up even if I leave you unattended from there.
Please turn a spring to the winding くにはりゅうずを starboard (12:00 direction) slowly. The spring does not roll up in the left direction (6:00 direction).
When you use the stopping clock, please carry it to an arm after turning りゅうずを 20 times, and rolling up a spring. The hoist of the spring can pass completion してもりゅうずを to this mechanical clock, but we do not have to worry to cut a spring.

セイコー メカニカル
The precision of the mechanical clock is decided by attachment

The mechanical clock is powered by the power of the spring and ticks away time because attachment (top-shaped parts) does three or four times of regular round-trip rotary motion for one second.
I continue round-trip rotary motion in the same period while repeating circling to the left if a balance spring attached to attachment is clockwise. I convey the round-trip rotary motion to ankle → escape wheel and move a needle.

セイコー メカニカル
I manage the speed with a speed regulator posture

The power that the spring rolled up is going to come loose reaches the gear, and a needle turns around, but it is the same, and a needle turns around at a violent speed and cannot tick away the right time. Therefore I regulate the turn of the gear to tick away the right time using "a speed regulator posture".
"The speed regulator posture" that combined "escapement" with "a temp" with isochronism becomes the heart part. Because I am similar to the form of the anchor of the ship, "an ankle" means parts stimulating the tooth of the ガンギ car in conjunction with a temp. The sound called "チチチ ..." of the mechanical clock catches the tooth of the ガンギ car by the nail of the ankle and is a sound when I come off. When a spring comes loose, the temp becomes gradually poor at vibration. Therefore, as for "the speed regulator posture," by little continues giving the leading swing stone of the temp power for a temp to vibrate adversely while I receive control of the speed from a temp.
