**Calibre FP 1185** (and the similar **Cal. 1186** and **Cal. F185**) is an [[ultra-thin]] [[automatic chronograph]] movement from [[Frederic Piguet]], now known as [[Manufacture Blancpain]].

===== History =====
Introduced by [[Frederic Piguet]] in [[1988]], Cal. 1185 is a [[modular]] movement but highly-integrated. It is based on F. Piguet's [[FP 1180|Cal. 1180]], a hand-winding movement, and is very similar in construction, with just the automatic bridge and winding system added.

Cal. 1185 has an [[automatic]] winding system and [[column wheel]] construction with a [[vertical clutch]]. Cal. 1185 beats at 21,600 A/h. It measures 25.6 mm in diameter and 5.55 mm in height, has 37 jewels, and [[power reserve]] of 42 hours. This makes it [[ultra-thin|the thinnest automatic chronograph]] made as of its introduction.

===== Variants =====
Cal. 1185 has been used by [[Blancpain]] (including a [[flyback]] model), [[Franck Muller]], [[Vacheron Constantin]], and [[Audemars Piguet]] in the [[Audemars Piguet Royal Oak|Royal Oak chronograph]].

  * **Audemars Piguet Cal. 2385** - Used in the [[Audemars Piguet Royal Oak Chronograph|Royal Oak Chronograph]], Ref. 25860, launched in 1998 as the first-ever Royal Oak chronograph
  * **Vacheron Constantin Cal. 1137** - Used in the [[Vacheron Constantin Overseas Chronograph|Overseas Chronograph]]
  * **Breguet Cal. 576** - Used in the [[Breguet Marine Chronograph|Marine Chronograph]]

===== Cal. 1186 =====
The similar **Calibre 1186** includes a [[rattrapante]] feature. This was the world's first automatic rattrapante chronograph and remains one of the thinnest at 6.9 mm. It is made up of 361 parts and has 38 jewels.

===== Cal. F185 =====
Another variant of Cal. 1185 is the [[flyback]] **Calibre F185**. Like Cal. 1185, it is just 5.5 mm thick. It also shares the same jewel count, 37.

===== Cal. 1285/1286 =====
[[Omega]] wanted an automatic chronograph and turned to F. Piguet to develop it. The result was the [[ebauche]] Cal. 1285 and Cal. 1286, a much-modified version of Cal. 1185/1186. They share many similarities but also have key differences This movement runs at 28,800 A/h, is larger and thicker, and some include a [[Co-Axial]] escapement for Omega. The [[subdial]]s are also modified All feature a 30 minute counter at 3 00, but the Omega ebauches have a 12 hour counter at 6 00, where the seconds are found on other movements in the family.

Versions 
  * [[Omega 3301]]
  * [[Omega 3303]] - Better finishing for [[Omega Speedmaster Broad Arrow]]
  * [[Omega 3313]] - [[Co-Axial]] escapement for [[Omega Planet Ocean Chronograph]]
