Longines 99x

[Achraf]

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
not all calibres made in all versions

Intr-un excellent articol - The Ebel 060 (Lemania 8810) http://www.thepurists.com/watch/feature ... srpt3.html gasim informatii extrem de interesante despre parcursul acestui calibru:
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:

Am gasit un Claude Meylan (Lemania 8810) http://forums.watchuseek.com/f20/lemani ... 43361.html

Cred ca si Chronoswiss si RGM au folosit acest calibru

[Claudiu]

Am si eu un Longines cu 99x.
Am sa fac poze si am sa le afisez.

[mihaieros]

Eu am un 994-4395 si un 990-4392
pun si poze daca e nevoie...
In orice caz, este unul din cele mai frumoase mecanisme automate... Lemania din cite stiu

[Achraf]

Orice poze si date sunt - evident - binevenite!
Incep eu seria cu cel mai rar dintre calibrele automatice 993, si anume Longines 993 (fara data si secundar central).

[Claudiu]

Am venit si eu cu pozele promise ale Longines-ului meu.

[User]

adaug si eu poze cu 40. Ref. # 995-4905
singurul Longines din seria 99x pe care l-am avut.

[Achraf]

Foarte frumoase aceste doua Longines-uri.
De fapt stiam ca le aveti, le-ati mai prezentat pe forum (parca - cel putin Ovidiu stiu sigur pt ca de-acolo am si luat ref. # si l-am trecut in tabel).

Calibrele mecanice (nu automatice) din seria 99x sunt rar intalnite.

O sa revin si eu cu poze de la cateva 990 si 994.

Sunt curios daca a vazut cineva (pe net ... macar!) calibrele 991, 997, 998 si 999.

[Alfie]

[mihaieros]

Lucian, toate aceste Longines-uri superbe sunt in colectia ta? Daca da, te felicit si te invidiez...din toata inima

[Alfie]

Sunt toate in colectia mea,le ''adun'' de ceva vreme.
Multumesc,cu rabdare gastsi si tu dar din pacate la preturi din ce in ce mai mari.
Discutam asta cu unul dintre colegi (via MP),criza a trecut de ceva vreme pe Ebay si din cate vad preturile au ''sarit" mult acolo
Longines nu are lista productiei 99x?
Trebuie probabil doar solicitata.

[Alfie]

Eu am un 994-4395 si un 990-4392
pun si poze daca e nevoie...
In orice caz, este unul din cele mai frumoase mecanisme automate... Lemania din cite stiu

Nu a fost initial Lemania.
Este unul dintre cele mai frumoase automatice cu tot cu problemele sale.
A "sarit "putin randul fiind produs prea devreme spun unii.
In epocaconcura cu Omega 711(si variantele sale) un alt mecanism modern dar insuficient testat si la fel ca si 990 prea scump.
http://www.ranfft.de/cgi-bin/bidfun-db. ... &Omega_711
Omega 711 are insa radacini Frederique Piquet,carcotasii fara minte care critica legatura curenta FP -Omega prin Omega 3133(am scris critica nu neaga).
FP Omega au avut o poveste de "iubire" destul de lunga prin Rayville.
Cine doreste poate sa solicite prin intermediul MP materialul care "povesteste" aceasta legatura.
Revenind la discutie,990 nu a fost deci singular in lupta pentru cel mai modern automatic.
Cu toate problemele legate de ineficienta armarii eta 2892 a fost invingatorul,ramanand pana astazi cel mai reusit automatic(cu multumiri Eterna )
990 a avut un predecesor in Longines 890 (pe care il caut cu disperare ,desigur in stare buna)
Solutia celor doua arcuri a fost dusa aproape de perfectiune de Favre Leuba,ceilalti au incercat si ei ..
Longines 890 a fost un mecanism "industrial" nu foarte frumos dar a fost un pas mare pentru Longines.
27 mm
inaltime 5.70 mm (din pricina celor doua arcuri)
Surprinzator 990 urmasul superb a fost produs doar dupa doi ani de proiectare /testare.
La momentul lansarii(1977) a fost cel mai subtire mecanism automat cu doar 2.95 mm inaltime.
A fost cantecul de lebada ... Longines

[razvyy]

La momentul lansarii(1977) a fost cel mai subtire mecanism automat cu doar 2.95 mm inaltime.

In 1977 cei 2,95 mm nu erau tocmai de invidiat, existau deja pe piata alte mecanisme cu armare automata mult mai subtiri. Piaget 12P sau Bouchet-Lassale cal. 2000 imi vin in minte.

[Alfie]

Da, asa este
Cei de la Longines spun ca 990 a fost in 1977 cel mai subtire din lume cu resort dublu nu cel mai subtire automatic.

Imi cer scuze si multumesc pentru corectie.
