====== Omega 1140 ======
**Calibre 1140** is a [[modular]] [[automatic]] [[chronograph]] movement from [[Omega]]. Introduced in [[1988]], it was replaced by the updated [[Omega 3220|Cal. 3220]] in [[2000]].

===== History =====
In [[1972]], Omega introduced an [[Omega Speedmaster Automatic|automatic Speedmaster]] using an integrated movement co-developed with [[Lemania]], [[Omega 1040|Cal. 1040]]. This was updated as [[Omega 1045|Cal. 1045]] in [[1974]], and remained in production through [[1988]]. In that year, Omega introduced a new movement for the [[Omega Speedmaster Reduced|Speedmaster Reduced]]. Cal. 1140 is a modular movement, combining the thin time-only [[ETA 2890-2]] with a chronograph module ([[DD 2020]]) from [[Dubois Depraz]].

The movement was updated in [[1996]] to become **Cal. 1141** and updated again the next year with the new [[ETA 2892-A2]] as **Cal. 1143**. These were mainly cosmetic and modernization updates, with the core movement remaining mostly the same. In [[2000]], Omega introduced another refresh, [[Omega 3220|Cal. 3220]].

===== Applications =====
Cal. 1140 was mainly used in the [[Omega Speedmaster Reduced]].
