The Alpina caliber 592 is a vintage manual-wind mechanical movement. This caliber was produced in the 1930s – 1950s/60s. The 592 has an Incabloc anti-shock protection (Incabloc was invented in 1934).

Northernman on the Omega Forums said this about the caliber 592:

“Alpina is one of the mostly forgotten “grand old names” of the Swiss watch industry. The caliber 592 was one of their finest designs. The quality and reputation is on such a level that some modern designer watches has come out during the last years with NOS Alpina 592 movements in them!
In 1948 the school of watchmaking at the cantonal polytechnic in Biel chooses the 12-ligne hand-wound Alpina caliber 592 to serve as the school’s didactic caliber. This choice underscores the fact that this movement was especially precise, reliable and robust.”
