Hi, I’m curious to know if any of our resident UG experts have ever come across a Universal Geneve compax of any kind from the mid/late 1940s with the case maker’s stamp and other marks on the rear OUTSIDE of the case, along with the serial and reference numbers that one would usually expect to see there...? This one pictured, from a yellow gold Tri-Compax, appears to show a hammer with 128 (Jung & Cie?), an owl (French gold?) and maybe a woman's side profile (??), along with 18k / 0.750. Perhaps this is an example of French cased watch, but I’ve never seen this outside placement before (I don't have Sala handy at the moment to check) and that has me wondering if something might be amiss. For what it’s worth, the inside of the case back simply has the Universal logo at the top, and “SWISS” at the bottom, and not much else is visible other than perlage finishing. The movement does not appear to have "HOX" or any other identifying stamps inside, other than the usual Universal Geneve wording, 481 caliber, etc. Any thoughts and/or other examples of similar markings/placement would be appreciated. Thanks!
