Yours is a quartz, there was a good guide online but with photobucket having changes all the images are gone. I think yours is full size quartz (there was a medium). The full are less common than mid size but quartz was the most produced model. Its the first generation model (Mercedes hands and single buckle) while the 2nd generation is sword hands and double buckle but there have been variations on both. It is a great set to have and so much more when it belongs to a relative.
