Understanding Orient model number for international models

I found this in the 2011 Orient catalog and thought it might be a useful resource for Orient fans out there.

The movement table below includes movements used in the models found in the 2011 catalog. It does not include movements that are not found in the catalog.

Can you see how the model number system work on these Mako variants?

If it is hard to visualize with the mako series, try these three Hogrider variants.

  1. Hi Thomas,

    That’s wonderful information! You have managed to ‘Break the Orient Code’! Now it makes sense. It’s a bit complicated but very useful information.

    Thanks for sharing it! I have a couple of Orients and their code has so far baffled me! Not anymore! LOL!

    Best regards always,

    I asked my father for the age of this watch, he said its about 25-30 yrs old.

    btw, i sent an email to Orient customer service, they didnt tell me the model name, but they sent me back the owner manual as PDF file. still no model name on it also but it fits all chronographs with alarm and tachymeter models that no’ starts with TA.

    Thanks again
    best regards

  6. I have an Orient Watch, its a flat square Quartz watch.
    I remember buying it in 1996/1997..

    The dial is like matt gold with 2 shiny polished squares for a 12 and 6, which are resembling 4 squares each.
    And 2 shiny stripes for the 3 and 9.
    The other numbers are black stripes.
    The dials are shiny gold.

    Under the square12 stands: Orient Quartz.
    Above the square6 stands a sort of 3towers. Under the square6 is in fine print: Japan – and a coupple of number i can not read at this moment.

    The case itself is stainless steel with the sides goldplated. Also 2 of the 7 rows of the band are goldplated.
    They are still shiny, and the watch is heavily worn.
    The movement wheel is goldplated and haa a black stone(?).

    On the backplate stands:
    Stainless Steel Back
    O (in a square) C20023-40 B2

    I would like to know more about this watch, Google doesn’t show any results.
