    Picture Breitling Jupiter/Jupiter Pilot - a brief history to aid identification

    Breitling Jupiter and Jupiter Pilot

    A brief history to aid identification and dating




    1980
    The 'Jupiter' was introduced in 1980 by Breitling in the year following the take-over of the company by Mr Ernest Schneider. Along with the closely related 'Mars' and 'Pluton' chronographs, the Jupiter was designed for military pilots but also with an eye on the civilian aviation market. There were various bezel options and differences between the three models but the movements and therefore the functions are identical.

    At this time, all Breitling pilot's watches were considered part of the 'Navitimer' range and the Jupiter was named 'NAVITIMER QUARTZ 2300' on the dial. It has a non-ratcheted combination bezel comprising a circular slide-rule (Type 52 derived from the Navitimer ref 806) and a wind-rose (compass degrees) scale. Between the these two scales are flight levels in two colours for VFR/IFR and East/West flight separation.

    The dial has a white Breitling wings logo, the design of which was heavily influenced by the logo of the AOPA (Aircraft Owners and Pilots' Association). The model reference 80390 is stamped into the case back.

    Circa 1983
    From around 1983 the Breitling wings were now gold in colour and the model reference was 80970. It is believed some early ref 80970's were fitted with the previous white-logo dial.

    The Jupiter has a Swiss made ESA Y2 900231 7-jewel analogue/LCD movement

    Please Note: Some owners have suggested that great care must be taken when removing or fitting a battery to the ESA Y2 900231 to avoid any shorting or incorrect polarity or contact and that this can lead to irreparable damage to the movement.


    Unfortunately, at the time of writing (2005), the movement is no longer available and being quartz with LCD is very often impossible to repair if faulty. There has been a report of an owner sucessfully having an ESA Y2 900911 movement fitted to his watch without any problems or change in functionality but this movement too is now obsolete.

    During the early to mid-1980s the Jupiter was produced for middle-eastern air forces. The Algerian Air Force version has the AAF wings, "ALGERIAN AIR FORCE" and "BREITLING NAVITIMER" on the dial. The Iranian military version has the usual Breitling wings with a Farsi (Persian language) inscription. The Iraqi Air Force version has the Iraqi AF wings on the dial and a special inscription on the case back.

    The manual (and movement) for the Jupiter ref 80970 is shared with the Pluton, the Cosmos
    and the rare Pluton Lady (a smaller version of the Pluton)


    1986
    By 1986 the Jupiter has been revised and is known as the 'New Jupiter' to differentiate it from the previous model. The new model reference is 80971. The New Jupiter is available in a choice of all-steel, bi-colour, or gold-filled. Water resistance of the New Jupiter is 100M. The revised dial has circular and arrow hour markers which look similar to some other Breitlings of the period such as many Tabarly models. Above the LCD readout are printed the words "NAVITIMER QUARTZ 3300". The bracelet is specifically designed for the ref 80971 and is also named "Jupiter".

    The movement is now the Japanese Miyota Y652 quartz which is shared with the updated Navitimer 3100 Pluton. Functions include 12 or 24 hour indication with two time zones, a split-seconds chronograph accurate to 1/100th sec, date and alarm.

    Like the previous model, the New Jupiter is supplied to the Iraqi Air Force.

    Higher serial number examples of the ref 80971 have been seen with "1884" on the dial below "BREITLING" but these may possibly be later replacement dials.

    1987
    The model ref is now 80972 although the watch looks the same as the ref 80971.

    Although sharing a movement with the Pluton and having the same functions, the Jupiter ref 80972 is listed at $790 compared with the Pluton at $550. The Pluton does not have an E6-B pilot's slide rule or sapphire glass although it is water resistant to 200M/660FT.

    Specifications for the Jupiter ref 80972 include:
    Sapphire crystal with anti-glare coating
    Water resistant to 100M/330FT
    Screw-down crown
    Turning bezel with E6-B slide rule and compass rose

    Functions include:
    Analog time, hours/minutes/seconds
    Digital 2nd time zone used for UTC/Zulu time
    Day/date, month
    Alarm and hourly signal
    Chronograph 1/100th sec with split function
    12 or 24 hour display
    Night light

    1988
    The Jupiter is replaced by the 'Jupiter Pilot', reference number 80975. The dual-function bi-directional bezel, the watch case shape, and the bracelet are passed on to the new model but the previous analog/digital movement has been replaced by a very different quartz chronograph caliber. The dial shows three sub-registers and the date in a round window at 4 o'clock. It is black with silvered sub-registers and has the word 'QUARTZ' printed on the left side. Although the previous Jupiter ref 80972 had a sapphire crystal, the Jupiter Pilot is fitted with an anti-glare coated mineral crystal.

    The movement, known as the Breitling caliber 59, is the Japanese Miyota 3S10 which measures elapsed time to 1/50th sec. Its alarm function is controlled by pulling/pushing the button at 3 o'clock.

    1989
    A new inner dial colour option, silvered with black subdials, is now available as well as the already existing black with silvered subdials.

    1990/91
    The model reference is changed from 80975 to the new Breitling format; the Jupiter Pilot is now ref A59027. The edge of the date window is now dial-coloured and the hour and minute hands are white.

    Available inner-dial colours: silvered with black sub-registers; black with silvered sub-registers; blue with same-colour sub-registers.

    1992
    During 1992 the profile of the case by the lugs is softened with a slight rounding to match a new bracelet design and the model reference is changed to A59028. The new bracelet is named "Jupiter Pilot" the same as the watch. It has a fold-out extension piece so the watch can be worn over a flight suit.

    1993
    The sub-registers of the blue dial are now silvered as with the black dial.

    1994
    By late 1994 the ref A59028 had a new dial and hands. The word "QUARTZ" on the dial was replaced with "ALARM" (or the German "ALARME" or French "REVEIL"). The previously round date window was now squared. The hands were revised with the luminous compound divided into sections and the red part of the second hand now at the tip. The dial colour options remained the same as before, ie silvered with black sub-registers; black with silvered sub-registers; blue with silvered sub-registers.

    1995
    Information from the German 1995 'Sales Handbook':





    1998
    Manufacture of the Jupiter Pilot is discontinued. Some watches remain on sale in stores until at least 2000.


    FAKES
    Fortunately, fake Jupiter/Jupiter Pilots are very rare, but they do exist.


    Unlike a genuine Jupiter Pilot, this fake has a conventional crown and pushers as well as other differences. Presumably it does not have an alarm function and bizarrely has the name of a completely different Breitling, CHRONOMAT, on the dial instead of ALARM, ALARME, or REVEIL.
