View source for ETA 2890

'''Cal. 2890''' (and similar '''Cal. 2892''') is an [[ultra-thin]] [[automatic]] watch movement produced by [[ETA]] from [[1975]] to [[1983]]. It was replaced by [[ETA 2892-2]].

==Overview==

ETA was one of the premier automatic watch movement makers of the 1950's and 1960's, and were allowed by [[Ebauches SA]] to develop a modern, ultra-thin movement for the [[1963]] [[Eterna-Matic 3000]]. This movement, [[Eterna 1466|Cal. 1466U]], featured many innovations, including a modular, one-plate design with the automatic winding works sunk into a depression at the center of the gear train. That movement was updated to become [[Eterna 1504|Cal. 1504]], operating at 28,800 A/h.

As ETA emerged as the strongest movement maker for the entire Swiss watch industry during the [[quartz crisis]], Cal. 1504 was updated to become '''Cal. 2890''' and, with [[quickset date]], '''Cal. 2892'''. Like their [[Eterna]] predecessors, they use a ball-bearing [[rotor]] and feature efficient "Eterna" gears for a power reserve of 42 hours.

Cal. 2890/2892 remained at 12.5 ligne (28 mm) like its predecessors, but it was replaced in [[1983]] by the narrower 11.5 ligne [[ETA 2892-2]], predecessor of today's [[ETA 2892A2]].
