====== JLC 928 ======
**Calibre 928** is a thin automatic watch movement with [[power reserve indicator]] from [[Jaeger-LeCoultre]].

Cal. 928 appeared around [[1985]], reviving one of Jaeger-LeCoultre's signature complications, the "[[Jaeger-LeCoultre Réserve de Marche|Réserve de Marche]], or [[power reserve indicator]]. The company was the first to bring this [[complication]] to market in [[1948]] with the [[JLC 481|Cal. 481]] [[Jaeger-LeCoultre Powerwind|Powerwind]] and has continued to market watches with this complication to today.

Cal. 928 an [[automatic]] movement based on the widely-produced [[JLC 889|Cal. 889/1]]. It runs at 28,800 A/h and has 43 jewels. It features central hour and minute hands and [[small seconds]] at 6 00. A subdial at about 2 30 shows the [[date by pointer]].

But it is the [[retrograde]] [[power reserve indicator|power reserve pointer]] centered at 10 30 that gives the movement its claim to fame. It swings counter-clockwise from about 6 30 to about 4 00 and watches feature a scale marked "0 - 10 - 20 - 30 - 40" and the "Réserve de Marche" title.

Jaeger-LeCoultre currently used this calibre in watch models named for this complication, the [[Jaeger-LeCoultre Gentilhomme Réserve de Marche]] and [[Jaeger-LeCoultre Master Réserve de Marche]]. Cal. 928/2 is substantially similar. Cal. 928 was produced from about [[1985]] through about [[2012]], when the [[Jaeger-LeCoultre Master Ultra Thin Réserve de Marche]] with [[JLC 938|Cal. 938]] was released.

Calibre 928 was also used by [[Vacheron Constantin]] as their **Cal. 1127**.
