====== Zenith 405 ======
Calibre **405** (and updated **405B**) is an [[automatic]] [[flyback]] [[chronograph]] movement from [[Zenith]]. Released in the 1990's, this was one of the first modifications to the classic [[Zenith 3019PHC|El Primero movement]].

===== Overview =====
As the El Primero renaissance continued in the 1990's, Zenith made the first major [[complication]] addition with the introduction of the [[flyback]]-equipped **Cal. 405**.

Because of the unconventional 4 30 date window placement in the classic El Primero movement, Zenith created a new calibre, **Cal. 405B**, which moved the date to the 6 00 position.
