Yellow gold filled, with a linen pattern silver dial sporting diamonds at 12, 3 and 9. "Bulova" on dial is applied gold, like the indices. I found this one a few minutes before the auction ended and didn't recognize it. My first thoughts were it was a Diamond Excellency that had a 3rd diamond mount added at the 12 position; which seemed unlikely as the DE (2 diamond) in this casing had the logo printed on the dial. "What the heck is that?". Next thought was is was a 3rd party dial (arched logo) with bling. Condition looked good and it was running, so I bid it because I liked the look. Apparently, nobody else thought it was "real", as I won it for $26.50. In hand, the logo looks like it was bent during a previous service and will stay that way..... It is currently keeping time.
Much to my surprise, it appears in the 1966 Linebook as genuine.

A first for me as well as the database!
