    Stumbled upon this cool vintage Omega box and crowns today. Would anyone recognize which Omega watch this box was made for?

    I'm also wondering how would one go about identify the Omega crowns shown photos.

    Yes, diameter, height, and stem opening size will make it easier to tell you the part number.

    More info on the case is here: https://omegaforums.net/threads/omega-box-for-which-omega.18345.

    For the crowns, you'd need exact measurements of the tap size and tube size - this can be done if you have some spare stems and case tubes available with known sizes. The diameter and thickness are also necessary to know which cases they were designed for.

    There's a similar box featured in this ad:

    The watch inside is an early Globemaster (no-name Constellation). I think the box could have been used on any of the pictured watches.

    So the larger silver crowns measure in as follows....

    1 silver crown is 6.45mm in diameter by 3.45mm in thickness.

    The other silver crown is 6.75mm in diameter by 3.75mm in thickness

    Gold crowns measure in as follows....

    2 of the gold crowns are 6.75mm in diameter by 3.25mm in thickness

    1 gold crown is 5.25mm in diameter by 1.65mm in thickness

    All measurements are approximate.

    I am a little lost on how to measure the stem openings.:confused:

    As @TNTwatch said,

    "For the crowns, you'd need exact measurements of the tap size and tube size - this can be done if you have some spare stems and case tubes available with known sizes. The diameter and thickness are also necessary to know which cases they were designed for."

    Once the crown is separated from it's original packet the only way to check threads/pipe diameters is by the "try it and see" method.

    Maybe @Archer or @Horlogerie could offer some advice?

    I can see why they call you ΩF InvestiGator.

    I have a quite similar "crown" situation to the OP, but hadn't got round to posting anything yet as my task is slightly more daunting. Absolutely great info from Baz9614 :thumbsup:. Are they all specifically Omega crowns, and am I right in guessing that it applies to current series parts from 1962 ? I think my stash of crowns ranges from the 1960-80s... any ideas where I could find later versions of the same documents ?

    Here are some pictures of my problem !
