Ebosa 52

Description

If you don’t look into the details, this ladies’ form movement looks exactly like a pallet lever movement, but on the second glance, you can see the pin lever escapement of the Ebosa caliber 52. Nevertheless, the whole construction of this movement is equal to that of compareable “better” movements.

The ring balance is not shock protected and does not have a long regulator arm. All gears run in synthetic rubies, the anchor wheel (and on the dial side the forth and third wheel, too) is beared in deck jewels.

As usual on cheaper movements, the winding mechanism is on the dial side and is only a rocking bar mechanism. This is not very service-friendly, but cheap in production.
