Ma gandeam sa deschidem un topic special pentru ceasurile echipate cu mecanismul automatic / manual 99x.
De fapt seria incepe cu cal. 989 si se termina pe la 999.
Preiau de pe pagina Ranfft cateva date:
http://www.ranfft.de/cgi-bin/bidfun-db. ... ines_989_2 When introducted in 1977, the 990 with all features was the thinnest automatic movement with date and sweep second; even in 2003 it is only underscored by movements without date and/or sweep second.

two serially coupled barrels, one with fixed spring, one with slip spring
Instead of the date ring, an hour angle disc is mounted, which is operated in the crown position for quickset date.
differences not known between versions 9XX, 9XX.1, 9XX.2

Caliber history and overview:
In 1975 Longines released the Calibre 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 Calibre 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.
Lemania purchased the design and presumably the tooling for the Longines 990 and began producing it as a Lemania Calibre 8810. In 1991 its design was refined in some respects and released as the 8815. The 8815 was expanded into a host of other movements including a skeletonized version (8881), one with a perpetual calendar (8840) and one with a quarter repeater (8860). The Lemania 8815 and its variants are currently used in a variety of watches from Breguet and a few other mostly high-grade manufacturers (a rare, more affordable watch with this movement was produced by RGM for a TimeZone limited edition watch in 1999).
Since Lemania's acquisition by the Swatch Group in 1999, Longines has re-released watches with this movement, re-labeled as a Longines 990. Whether the Lemania 8810 continued to be produced after that or Ebel purchased a new old stock movement for their Ebel Calibre 060 is unclear to me. At any rate, the Ebel Calibre 060 found in this limited edition Ebel Lichine automatic is clearly marked on the barrel bridge as a Lemania 8810 (in addition to the Ebel calibre designation).
Asadar, ca sa sintetizam, avem mai multe denominatiuni derivate din calibrul de baza Longines 99x, cum ar fi:
Longines 990
Ebel 060 / 080
http://www.pmwf.com/Phorum/read.php?10,86018,86018 Lemania 8810
… iar eu am gasit si la Girard Perregaux cal. GP 214-157 / Longines 994
Cine mai foloseste acest calibru in afara de Longines, Ebel si GP? Ce informatii am mai gasit:
