I have owned a Calatrava 3919J for over 20 years. It was the first PP I ever owned, a gift from my parents upon my college graduation. Other than its sentimental association, however, I have grown somewhat ambivalent about this watch, though I'm not sure exactly why. I do need a dress watch, however, and have come to admire the 5127J and especially the more recent 5124G. I know that some forum members might urge me to keep the 3919J and get one of the others at a future date; assuming for purposes of argument that I could only have one, however, is letting go of the 3919J for one of the other two a sensible move? Please help me to resolve this dilemma! Thanks.
