ETA 2472

The 2472 is a mechanical movement with automatic winding, date display with semi-quickset feature, and power reserve of 42 hours.

This movement features a semi-quickset date feature, more advanced from all other members of the ETA 2400 family apart from the similar hand-wound 2408. The date changes instantly at midnight. To set the date, the time is moved forward from 20:30 to 24:00, then back to 20:30 and forward again.

The 2472 was very popular due to its compact size and excellent performance. It was a state of the art movement for much of the 1960's, with the bidirectional automatic winding, date feature, and direct central seconds cited as advances. The 18,000 A/h balance motion would quickly be eclipsed, but the 2472 was capable of chronometer-grade performance thanks to precise regulation using a moveable hairspring stud and long regulator arm.

Similar movements are the 2474 and 2475.
