    Pictures of notable HAQ movements and watches ...

    This thread is a resource for pictures of notable HEQ movements. Pictures of watches that they are installed in can be included as well.

    If you have a high quality picture of a movement not shown here, please consider posting it here. I would prefer if you uploaded the picture directly to the forum, rather than providing a link. This way, it will be a permanent resource for the forum.

    Thanks

    First contribution. Citizen A660H. Crrently the most tightly spec'ed non-RC movement made. Used exclusively in the "The Citizen" line, which has also been called the "Chronomaster" line starting in '05. The third picture shows an '04 model. The fourth pic shows a model from the first year that the line came out ('95). Note the conservatism and the minor design changes for the first ten years. The last picture shows an '05 model (courtesy of Pierre deBrial). This year marked a notable design change.

    Next is a Seiko Twin Quartz (Courtesy of Ian Fogden). This movement used two crystals operating at different frequencies to enable temperature correction. It was introduced around 1978 as best we know. There is conflicting information on the performance of this movement, with some documents indicating that it was spec'ed to five seconds per year, and others indicating 20 seconds per year. Whichever is correct, it was a remarkable and innovative approach to temperature compensation.

    Next up is a Rolex Oysterquartz 5035 movement. (The picture is courtesy of Jocke.) It's day-date cousin is the 5055. Introduced in 1977, it is the only TCVCXO thermocompensated movemement known. Rolex never officially stated a specification, but unofficially we understand that 60 seconds per year was to be expected. A remarkably well made and finished movement, it was discontinued in 2004.

    <Due to operator error, the pics did not get attached. See the next post for these.>

    Here is the Seiko 9F, used exclusively in the Grand Seiko line as far as I know. It is spec'ed to 10 seconds per year, except for the 9F61 (shown), which was a special issue in 2000 that was spec'ed to 5 seconds per year. It has also been stated that it is designed to need no maintenance for fifty years. (Watch pic by Rex.)
