Vintage ladies Rolex - can anyone identify this?

This watch turned up in a collection of inherited jewellery that a relative has got. Does anyone know anything about what model this is, or what its value might be?

erm for some reason this image doesn't seem to show up. Promise I'm not trying to bump this post, just trying again to show the photo:

My missus has one verysimilar, though not the same. Quartz with a blue, gold dust encrusted dial. We were told by a very respected and knowledgable (but not authorised) dealer that it's called an "orchid" and worth between 3-3.5 grand.
