    My Valjoux 7750 Thinks its a quartz

    My Valjoux 7750 movement 18ct Tissot Time Lord regularily keeps pase with my Breitling Quartz.

    after 7-8 days there can be just a second or so difference I dont wear the watch very much but it is the only watch I use

    If my Breitling 1997 Pluto was running wrong then surely they would not match, the chances of both watches have the same loss would be too high.

    This watch has a heavy gold case 2 troy ounces gold, could this be absorbing magnetic interference?

    The Watch has a see through back its not Quartz.

    Thanks Watchbreath,

    It is my first good automatic and I am still amazed everyday, It is not surprising that high end designer watches use this movement. How could you better it and at what cost? A friend Purchased a HUBlot big bang ($30,000) and the movement looked like a variation of the Valjoux.

    Snappit I have seen this link on the Valjoux before it makes the point well I would like to know if Valjoux have made any incremental improvements over the last few years.

    I saw another thread cant remember where, and the owner was getting the same good time keeping.

    Now After 1 Month approx 10 seconds difference from Quartz watch

    It would be great to see an updated article on the Val 7750 movement to see if they have changed anything.

    I think , Optix, that the 7750 can be thought of as a workhorse movement much like the famous Chev V8 357. It is incorporated into so many models in many different final configurations its impossible to say that there is "one" Vj7750. Breitling, for example, and one that I feel I can comment on, transforms the movement into a high performance engine, enhanced, refinished, elaborated and renamed into a Breitling caliber like the B13...in their own dedicated facility. They control for many factors and enhance where necessary components that fall short of specification expectations. They then submit the final assembly to COSC testing to assure consistent statistical quality control across their entire production of more then 100 thousand watches per year.

    We know of six versions currently...

    B13 Valjoux 7750
    B20 Valjoux 7750
    B 21 Valjoux 7751
    B 23 Valjoux 7750
    B 24 Valjoux 7754
    B43 Valjoux 7758

    This is their way of ensuring the performance they require for the market they aim to satisfy. The Vj7750 is complemented by other movements in the line up. This range of motors(calibers) gives the maker a tremendous range of possibilities when designing the next year's models and helps them satisfy what ever segment of the market they wish to address.

    Some of the other movements in the current stable...

    B10 ETA 2892-A2
    B12 Lemania 1873 or 1877 (handwound)
    B 15 ETA 2892-A2
    B17 ETA 2824
    B18 ETA 2892-A2
    B19 ETA 2892-A2
    B 22 ETA 2892-A2
    B 26 ETA 2892-A2
    B 27 2006 Skyracer (Base movement unconfirmed)
    B 30 ETA 2892-A2
    B 32 ETA 2892-A2
    B33 ETA 2892-A2
    B34 ETA Piguet Rattrapante 1186
    B35 ETA 2892
    B36 ETA 2892
    B38 ETA 2892-A2
    B39 ETA 2892-A2
    B40 ETA 2892-A2
    B41 ETA 2892
    B42 ETA 2892
    B44 ETA 2892
    B45 ETA 2834-2
    B48 2005 Montbrillant (base movement unconfirmed)
    B49 2006 Cockpit Big Date ETA 2896 (22 jewels)

    The above is just one makers line up. What another maker might do is entirely up to them. Tissot has a long horological history. The fact that they produce a well tuned movement keeping excellent time is no surprise to me given the base movement they have chosen for your particular watch.

    Thanks SnapIT for your in depth reply,

    P.S. If I had to choose one watch that my life depended on it would be a Breitling.
