    Hermetique Cased Marvin... What did I buy? Help with Identification

    I had been watching this listing for a while, because I liked the way it looks. Almost 1 year goes by and I decide to though in a 33% of asking price offer to start haggling. To my surprise it got accepted immediately. And boy, it sure doesn't disappoint either. Been on my wrist for a while now. Super pleased with the way it looks and feels.

    I was hoping the experts in this forum could tell me a little more about this piece. My knowledge beyond the 1950's is basically non-existent for watchmaking.

    Specifically:
    1) What movement maker and manufacture year? (listing said "1920's")

    2) Originally a wrist watch, that is this was never meant to be a pocket watch?

    3) Case purpose; where these for water or dust? Military perhaps?

    Case markings are 18K and the gold hallmark seems to be the Swiss Helvetia (women's head) Swiss Cross and finally "J.F." which I could not get a good picture of but is below Swiss made and the serial # 518605

    The large text says: "Double Boitier Hermetique" and "BREVET 89278"

    (google tells me Brevet has something to do with commissioned officers receiving a higher rank as a reward?)

    Thanks in advance :)

    Brevet = Patent
    J.F. is the Swiss case maker J. Finger
    The case is one of the first example of waterproof
    It is a wristwatch but not military
    The movement is a Marvin

    You don't happen to know the calibre or Date?

    What size is the movement? If ca. 23mm (10.5'''), it should be a Marvin Cal. 500. The one in Ranfft has a different bridge style:

    bidfun-db Archiv: Uhrwerke: Marvin 500

    ...but the one here (ca. halfway down the page) has your bridge style and the same keyless works as the one in Ranfft:

    Uhrforum-Werksucher

    ...so I think that the differences are due to different movement generations. Nice watch, BTW!

    Thank you! Amazing sources. With calipers it measures 22.74mm (Close enough to 23 I take it).

    Indeed it looks very close to the Marvin Cal. 500 from you second source. But I imagined this one is older than the 1936 date they put on that Cal. 500

    The biggest difference however is that mine has 17 Jewls, instead of 15 (on both links). Maybe they cut down the jewel count to save money at some point? And the Cal. 500 is based on this slightly earlier rendition.

    Edit: They could have also either lied, or inflated the Jewel Count as a selling point. I heard some companies used to do this

    Swiss watches came with varying jewel counts depending on application. It’s extremely unlikely that Marvin ever lied about jewel count.

    The 15 vs. 17 jewels is nothing - they often made the same calibre in different versions with different jewel counts. As for the manufacture date, they admit that they aren't quite sure and that 1936 onwards is their best guess. You may well just have disproved that. Or perhaps your estimate on your own watch is a little out.
