Langendorf 1054

Description

The Langendorf 1054 was, probably for export into the USA, rebranded as “Lonville 1004”, which made its identification a bit difficult.

It is visually very appealing with its beautiful stripes decoration, then golden-toned Glucydur screw balance and the waisted long regulator arm.

base plate

The base plate of this 17 jewels movement shows the typical signs of a mid century production. All fast revolving bearings are ruby-equipped and at 6 o’clock, there’s the second wheel, which can carry (but not on this movement) a decentral second hand on the dial side.

The gear train is also very typical for that time with its directly driven center minute wheel, third wheel, second wheel and steel escape wheel.

The pinion of the third wheel is prolonged on the movement side and carries the driving wheel for the center seconds wheel.

The golden toned Glucydur screw balance with its very small waisted arms is already beared in two Incabloc shock protection bearings. With 18000 A/h it beats contemporarily slow and can be adjusted with a long regulator arm.

Langendorf 1054: Dial side

On the dial side, you can see, that this movement could also have carried a decentral second hand at 6 o’clock, but the Langendorf 1054 already had a top modern center second indication.

Of course, like all quality movements, it also has got a yoke winding system.
