ETA 2410

Description

The ETA 2410 has got a diameter of only 6 3/4 lignes and belongs to the smalles ladies' watch movements of the 50ies and 60ies.

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. The good timing results are also guaranteed by the gold-toned screwed Glucydur balance - this was top of the line at that time.

Visually, this movement is a very nice one because of its slowly beating golden-toned screwed balance!

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 faster (6 A/s) beating version of this movement is known as [97]ETA 2412.
