Universal Geneve, cal 267. Case is the larger 34mm version, and also the case style is very uncommon faceted lugs. This style watch is almost always completely rounded case versions, which I don't find as interesting. (This is the only case style like this I have seen in recent memory, and the reason why I purchased and overhauled). The dial has the blue 24 hour scale, and is *almost* perfect. Warm champagne color, only flaw is a radium burn from the hour hand near 2 oclock. Blued hands have beautiful aged lume, as does the dial, with silver seconds hand showing some corrosion, which is common. Case is sharp, unpolished, in good condition top and sides, showing some wear/corrosion on the back, along with the case back. Thankfully the mvmt is pristine (please see last photo from watch maker during service). 18mm lug width. Serial places the watch between 43-45. I think the crown is not original? Watch has just been fully serviced at cost of $185, running great. This watch was not cheap to purchase or service, but felt the dial and case warranted the expense. Asking $600 USD, net to me, paypal, free shipping CONUS, intl at buyers cost. No returns unless grossly misrepresented. Plenty of refs here and Ebay.
