The Eterna 1402UW watch movement shares similarities with the ETA 2522 movement, including Kif shock protection, a different rotor shape, and an anodized alumina barrel with life-time lubrication. It is likely that the only difference between the Eterna 1402UW and the previous model, the 74, is the designation change in 1966. The movement offers the following functions: automatic winding, sweep seconds hand, and a date feature that can be set by adjusting the 20:40-24h. This movement was commonly used around the year 1966.
