Description

The ETA 2412 has got a diameter of only 6 3/4 lignes and belongs to the smalles ladies' watch movements of the 50ies and 60ies. Dugena called it Dugena 1201.

The speciality of this movement is, that its minute hand is no longer driven directly, but indirectly on the dial side by the train of second wheel. The first wheel stays in contact with the mainspring barrel and drives the whole movement.

The advantage of this construction is, that the mainspring and the balance both can be as large as possible, ensuring long running time and high precision. Even better timing results were guaranteed in the version with the golden toned Glucydur screw balance - visually clearly a highlight!

On the dial side, you see the familiar ETA construction with the yoke winding system, the printed minute dial part, the preparations for further cap jewels (on the 17j version) and the non jewel-beared train of the second wheel (at "8"), which drives the minute wheel.

The slow (5 A/s) beating version of this movement is known as ETA 2410.
