まず、裏蓋を開けた様子です。
First, here is a view of the open back cover.
破損が見つかりました。
ローターの軸が触れるルビーが破損しています。
この部分は負担が大きく、破損しやすいです。
ガタつきが大きく、これでは正常な自動巻きは見込めません。
Damage was found.
The ruby where the rotor shaft touches is damaged.
This part is under a lot of strain and is prone to breakage.
The backlash is large, and normal automatic winding cannot be expected with this.

ガンギ車に用いたれた保油装置を見てみましょう。
角速度の高い
ガンギ車は、オイルが動き、揮発しやすい為、
ルビー2枚ででオイル挟み込むことで、オイルを多く保持できるよう、
工夫がなされています。
Let's take a look at the oil-retaining device used in a escape wheel.
Since oil tends to move and volatilize easily in a ganghee with high angular velocity, two rubies are used to hold oil between them to retain more oil.

組み上げながら、ここでは、自動巻の仕組みを紹介します。
錘(ローター)がどちらに動いても
一定の方向でゼンマイを巻き上げます。
ローターの動きが右回転と左回転で、変化した時に
赤で囲った2つの小さな歯車が左右に揺れて、下の歯車を
経由するか、経由しないかで回転方向を整流します。
右の大きな銀色の車(角穴車)が2枚重なっているのは、
自動巻が作動している時にリューズに
力が伝わらないようになっています。
While assembling the watch, here is how automatic winding works.
No matter which way the weight (rotor) moves The rotor winds the mainspring in a fixed direction.
When the movement of the rotor changes between right-rotation and left-rotation, the two small gears circled in red swing to the left and right. The two small gears circled in red swing to the left or right, and the direction of rotation is determined by whether the movement is via the lower gears or not. The direction of rotation is rectified by going through or not going through the lower gear.
The two large silver wheels on the right (square bore wheel) overlap each other to prevent force from being transmitted to the crown when the automatic winding is in operation.

実際に自動巻が動いている様子です。
ピンで触っている小さな歯車が左右に少し揺れているのがわかります。
逆回転を防止する鳥のクチバシのような爪(第2コハゼ)の音が独特で、
着用時にはビーズを転がしたような優しい音色がします。
This is a shot of the automatic winding actually in motion.
You can see the small cogwheel touched by the pin shaking slightly from side to side.
The sound of the claw like a bird's beak (second kohaze), which prevents reverse rotation, is unique, When worn, it has a gentle tone like a bead being rolled.

続いて、時計の駆動輪列について、解説します。
ここでは、歯車以外のパーツを外して撮影しています。
針の付く車は、一般的な時計と異なり、
金色の大きな葉は無く、鉄製のカナのみです。
赤丸の下に見えるのが、分針の付く分カナで、
上にあるのが秒針が付く秒カナです。
センターの部分に大きなパーツを置かないことで、
自動巻機構のスペースを確保しています。
Next, the driving wheel train of the watch is explained.
Here, all parts except the gears are removed and photographed.
The wheel to which the hands are attached differs from a typical clock, There is no large golden leaf, but only an iron cana.
The lower part of the red circle is the minute canner where the minute hand is attached, The upper one is the second cana where the second hand is attached.
By not placing a large part in the center of the watch, The space for the automatic winding mechanism is secured by not placing a large part in the center section.

秒カナを外して横から見た写真です。
青で囲った中間車は2重の歯車ですが上下で固定されていません。
そのため回転力が、①から④へダイレクトに伝わらずに
②③を経由します。このことで、常に分カナに力がかかります。
これによって、使用時に分針がガタ付きません。
This is a side view with the second canner removed.
The intermediate wheel circled in blue is a double cogwheel, but it is not fixed at the top and bottom.
Therefore, the rotational force is not transmitted directly from (1) to (4), but through (2) and (3).
(2) and (3). This means that force is always applied to the minute hand.
This prevents the minute hand from rattling when in use.

こちらが、秒針を抑える仕組みです。
赤で囲った秒カナと分カナの間に受け(Bridge)が入ります。
青で囲った銅色の板バネ(Friction spring)が秒カナを適度に押さえます。
これによって、秒針がフラつく、針飛びを抑えます。
This is the mechanism that restrains the second hand.
The bridge (circled in red) is placed between the second and minute handles.
The copper-colored friction spring (circled in blue) moderately holds down the seconds hand.
This prevents the second hand from wobbling or jumping.
