**Calibre 3888** (and the similar **Calibre 3890**) is an [[automatic]] [[Co-Axial]] [[chronograph]] movement from [[Omega]] with a novel arrangement of registers.

===== History =====
In [[2008]], Omega introduced the [[Omega Speedmaster 5-Counter Chronograph]], an automatic chronograph with a highly unusual arrangement of [[subdial]]s Like the Olympic Rings, five overlapping dials show running seconds, chronograph days, day of the week, chronograph hours, and chronograph minutes. The watch was powered by a newly-designed automatic movement featuring Omega's trademark [[Co-Axial]] escapement. It is a [[column wheel]] design and is a certified [[chronometer]].

Two years later, Omega released the related **Cal. 3890** with the same functions but using a disc and window to display the day of the week rather than a pointer.

===== Applications =====
  * Cal. 3888
    * [[Omega Speedmaster 5-Counter Chronograph]]
  * Cal. 3890
    * [[Omega De Ville Co-Axial Chronograph 4 Counters]]
