====== J89 ======
Calibre **J89** is an [[alarm movement]] from [[Junghans]] produced in the 1950's.

Advertised as "Minivox", Cal. J89 was unusual in that it used a single [[barrel]] for both the alarm and timekeeping functions of the watch. The alarm was set using a crown at 2 00 and turned on or off using a [[switch]] at 4 00.
