**CFB A1000** is the first series-produced [[peripheral rotor]] [[automatic]] watch movement, introduced in [[2008]] by [[Carl F. Bucherer]].

===== Overview =====
Cal. CFB A1000 was important in many ways for [[Carl F. Bucherer]]. When it was introduced at [[Baselworld]] [[2008]] after three years of development, the young brand took the step of becoming a [[manufacture]]. The company had recently acquired movement specialist [[Téchniques Horlogères Appliquées]], and this gave them design and manufacturing capability to produce this groundbreaking movement.

Cal. CFB A1000 was also technically important Although patented in [[1955]] (by [[Paul Gostel]]) and produced in limited numbers from [[1970]] to [[1985]] by [[Patek Philippe]] ([[PP 350|Cal. 350]]), a true [[peripheral rotor]] automatic movement had never been produced in large scale. [[Citizen]] came the closest in the 1960s with the [[Citizen Jet]], but this was more of a geared [[central rotor]] and did not run around the periphery of the movement. Carl F. Bucherer developed many new technologies to bring the peripheral rotor to production, using [[DLC]] glides with [[ball bearing]]s mounted on spring-retained rockers. The transfer wheel between the rotor and winding assembly has two [[Incabloc]] shock absorbers to prevent the staff from breaking with vigorous movement.

Another technical advancement is the "Central Dual Adjusting System" ([[CDAS]]), which locks the [[index]] and balance spring carrier in place. It requires a specially-designed key to adjust the timing of the balance.

This unique design allows the entire movement to be viewed through a [[display caseback]] and allows the company to install modules on both sides if needed. One challenge of a peripheral rotor system is the location of the [[stem]] and [[crown]] Patek Philippe mounted these to the back of the movement, while the Carl F. Bucherer movement was thicker, allowing a traditional side position.

The first watch to be produced with Cal. CFB A1000, the [[Carl F. Bucherer Patravi EvoTec]], was released for sale in [[2009]]. By this time other manufacturers were working on similar technology. [[De Witt]] would introduce [[DW 8014|Cal. DW 8014]] in [[2010]], [[Audemars Piguet]] would follow with [[AP 2897|Cal. 2897]] in [[2011]], and [[Cartier]] with [[9603 MC|Cal. 9603 MC]] in [[2012]]. Cal. CFB A1000 received the "[[Golden Balance]]/Special Technology Prize" of the German [[Uhrenmagazin]] in [[2009]].

The replacement, [[CFB A2050|Cal. CFB A2050]], was introduced in [[2016]]. It was more affordable, with a traditional [[free-sprung]] balance and plainer finishing.

===== Cal. CFB A1001 =====
The similar **Cal. CFB A1001** adds a [[big date]] module to Cal. CFB A1000.

===== Cal. CFB A1002 =====
The similar **Cal. CFB A1002** adds a [[power reserve indicator]] to Cal. CFB A1000 and was introduced at [[Baselworld]] in [[2010]].
