I think with my watches Rolex Pres DDJJ, BP 5004, 232, 372 and 112 G, if the right time and watch like up, I will replace the 112 G. Ideally it would by either a 127G or Slytech. And if I can get over the gold Rolex I've owned since 1986 or any need for a dress watch, It could go and mu collection would look a little more historic and militaristic. It is possible I could just trade the 112 for a BP 5002, I love the watch both 5004 and 5002. Still married to that damn Rolex.
That said, you simply can't go wrong with the 5002 and you can't go wrong with the 5004 if indeed it sings to you. Two different watches, which is oh so nice as you can own them both.
