Eterna med lidt sjælden kaliber

Dengang brugte Eterna kun egne værker, og var iøvrigt forløber for en del ETA værker som vi ser idag, dengang var Oris et skoleur dog af den bedre slags.

Ja ETA er jo helt enkelt en offspring fra Eterna (eller Eterna ofspring fra ETA) idet de mente at ved at separere værks produæktionen fra, ville de kunne tjene langt mere - og i mange år var de to rene søstre og mange af de mest bruge værker fra ETA kommer fra Eterna. Et lille klip fra Timezone - håber det må være OK:

The 2892 is the most recent ETA (basic automatic) caliber and, unlike most of the other ETA's currently in production, the 2892 was derived from an outside design, the Eterna-matic 3000, Cal. 1466-U, first released in 1963 (by Eterna). When finally made available as an ETA movement in 1976, it was very flat for an automatic with center sweep and date, had a distinct developmental history outside ETA and had accumulated a very good record of reliability in the Eterna watches.

An historical note: ETA was the movement manufacturing division of Eterna until 1932 when it split off and joined Ebauches S.A. (which included other big manufacturers like A. Schild). Eterna continued independent development of movements (which is how it came up with the 1466U/2892), although Eterna and ETA also worked jointly on some designs. Almost all (all?) ETA and Eterna automatics share the Eterna-designed automatic winding system: a ball bearing mounted rotor winding in two directions via springless twin click wheels and two reduction wheels on the locking wheel
