Hi everyone: I have bought this watch in '03 from a California dealer. He stated it was NOS bought from an estate sale from a former long-term employee of Heuer. One source from the brand tells me its a Pasadena, but it does not look like other Pasadenas I'm familiar with; granted I'm not expert. I'd greatly appreciate any insight on the piece. I love it. It had a flat crystal, but when the seal failed it was restored with this domed crystal. Thank you.
