For those of you not around long enough to remember, I bought this watch for $26 on the Bay. It was too small for me but the right size for the wife. I just got it back from the AD with an authentication of it being a genuine Breitling. I still have never seen another like it so I had to take the next logical step. Crack the back to see what makes it tick. Turns out to be a Harley Ronda 375 (Swiss made). The only mention of Ronda in the Richter book is a model # 81500 with a Ronda 732. These 2 times could be the only time this movement was used. Seems like every time I open the back of a Breitling it seems to be an addition to the Richter book.
