====== SL 980 ======
Calibre **SL 980** (and similar **2980** and [[Breguet]] **579**) is an [[alarm movement]] from [[Lemania]] introduced in [[1969]].

As [[Jaeger-LeCoultre]] advanced their [[Jaeger-LeCoultre Memovox|Memovox]] alarm calibres and introduced advanced automatic movements like the [[Jaeger-LeCoultre 815|Cal. 815]], their competitors set about producing their own automatic alarm movement. [[Lemania]] was charged with the task, and introduced Cal. 980 in [[1969]]. It featured state of the art features like a [[Glucydur]] balance, self-compensating [[hairspring]], and a free-spinning central rotor. This single rotor wound a single [[barrel]] which drove both timekeeping and alarm functions.

Unlike the Jaeger-LeCoultre movements, Cal. 980 could be set with to-the-minute accuracy. Because both hour and minute of the alarm could be set independently, watches with this movement were often branded **Dual Alarm**.

Cal. 980 was wound and set using a pull-piece at 2 00 and the crown at 4 00 

  * Pulling the 2 00 piece to first position enabled the alarm. Pushing it in disabled it.
  * Pulling the 2 00 piece to third position, the crown allowed the alarm time to be set, both hour and minute, in both directions.
  * With the 2 00 piece in either other position, the crown set the time.

===== Variants =====
This movement was used by [[Breguet]] (as their Cal. 579) and Omega (as their Cal. 980) in their [[Omega Memomatic|Memomatic]] line. The "native" Lemania version was called Cal. 2980.
