Can't identify my 70's Heuer model

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.

Hi-well the dial seems to be from the so-called 'no name' Pasadena but I'm afraid the case is unlikely to be original nor Heuer. Have you looked inside to see the movement and whether it's signed Heuer or not?

Thanks, Steve

Hi Steve: I have not personally, but the watch has been serviced by a Heuer shop and they did not alert me to fraud. A woman at Tag Heuer hq identified it as a Pasadena, but I wanted more details. I will dig deeper.

Interesting. Were you given a model number? If you have it on email and could forward over to me what they sent you I'd be glad to take a further look into it.
Thanks, Steve
