    Good evening,
    I have this caliber Longines for quite a few years, It has no number Longines so impossible to know anything, even on the why of non-numbering and that's what concerns me.
    Would someone have a little explanation?

    Thank you
    Jean François

    looka like a 12.68z, check Ranftt.

    If it is, do you want to sell the dial?

    yes it is 12.68Z is registered on the movement.
    This is not a reassembly, the dial is part of the watch. can be found a box to make a wrist watch

    That’s interesting, lovely movement with geneva stripes and very nice dial too. Makes one wonder whether those parts were stock parts that somewhat filtered out of their factory before it even received a serial number.
    You should find a case relatively easily for that, if you take all of the measurements and seek help from Longines’ brand heritage department to figure out what size and type of case you need to fit it.
    They would probably be quite interested in that un-numbered movement too.

    Best regards

    "Makes one wonder whether those parts were stock parts that somewhat filtered out of their factory before it even received a serial number."

    That's what I suppose, because I got this watch with this one: a 30Z caliber never marketed; May nothing is certain

    Well on the second one you have a serial number so you can ask Longines for an extract of archive.

    There were some movements that left the factory without having been sold, and Jean's is apparently one of them. A beautiful movement, for sure.

    This looks like what Ive seen as marketing/shop window "correct time" chronometer watch, but without the casing

    Never seen an unmarked 12.68. Have you checked if the serial number is somewhere else on the movement (maybe below the dial)? dibs on the second one (the chronometre).

    First of all, thank you tony for your answer which seems to me the good one.
    Dodo I'm not a watchmaker to disassemble a movement, but it will surprise me that the number is elsewhere than on the bridge. I will have it disassembled to see if ..

    Jean –

    Like you, I wouldn't expect there to be a serial number beneath the bridges.

    I own a Longines pocket watch with a rare movement that was never sold. It does have a serial number, and is in the Longines historical records. I plan to create a post about sometime soon.

    Cheers,

    Tony

    Another one without a serial number. Shock protection is unusual (for Longines) too. Style of movement and dial suggest an early example of this caliber from the beginning of the 1930's.

    It would be interesting to see the «dial side» of these sterile movements.

    fantastic watch - dibs! - but the strap doesn’t fit at all. You need a gray strap or taupe or tan pigskin to bring out the color of the dial.
    also Iizard for me works best with gold dress watches- it’s a shiny dressy texture.
    For vintage steel watches I personally prefer flat straps in smooth leather, pigskin or grained calf. Matte crocodile can also look nice.

    What size is the watch?
