I bought this 30 Jewel on eBay from a seller who seems to specialize in classic Bulovas. It seems that all the watches they sell are restored by them and seem to be in excellent shape, so I felt very confident in spending a little more than I usually like to on this gorgeous watch.
Unfortuately, the stamping on the caseback was either originally very shallow and has worn over time, or was worn down during it's restoration when the caseback was polished. Either way, I could not find any date or case number, but the movement is dated 1961 (M1). The inner caseback is stamped "BEZEL GOLDLAYERED G 40 MICRONS" then there looks to be a case maker stamp and other case maker information. It looks like the case maker is MLB Modele Depose, I believe, but I'm not sure who that is as I've never seen it before. These stampings are what confuse me the most on this watch. The movement is a 10BZAC and has, of course, 30 jewels.
The dial is marked "BULOVA 30 Jewels" and "SELFWINDING". The hands and markers and been redone and glow brightly.
The watch showcases exactly what I love about vintage Bulova watches: The style, elegance, and panache of late 50's and early 60's America. That "Breakfast at Tiffany's" style, to quote the seller. But it's that time in American design that really speaks to me, and why I love this watch. It's another one that only comes out at special occasions.
Any help and information on this watch is much appreciated!
