\[WTS\] vintage Longines automatic L994.1 ref 4184, serviced Caliber history and overview: In 1975, Longines released the Caliber 890 automatic movement. It's defining feature was the twin, stacked mainspring barrels that gave the high-beat movement a longer power reserve while simultaneously decreasing the torque (and stress) on the rest of the movement. Another advantage of the twin barrel arrangement was a flattened power curve, giving the movement greater isochronism. In 1977, the design was further refined and updated with the introduction of the 990.1 automatic movement. Its height was reduced from 5.2 to 2.96 mm by placing the twin barrels side by side and simplifying the automatic system to wind in one direction only. In this configuration it remained the flattest automatic movement for close to a decade and is still regarded as a very advanced design. The Caliber 990 (and its variants) was the last automatic movement to be manufactured by Longines. It was produced as the 992 (no date), the 993 (no date, no seconds) and 994 (w/ date, no seconds) with either 25 (.1) or 17 (.2) jewels. Within a decade of its introduction, rising costs coupled with the onslaught of inexpensive quartz technology caused Longines to begin outsourcing all of their mechanical movements. The irony is that Longines was part of the consortium of Swiss manufacturers that pioneered the Beta 21, the first ever quartz movement, thereby sealing their own fate as a movement manufacturer.
