But I already laid my bet on the UN Marine Perpetual. As much as I liked the Acqua Perpetual, their stainless steel bezel was no match for the blue enamel bezel inlay coupled with the blue enamel dial. It is the richest blue I have seen on a watch dial.
Whichever model there is no doubting, the sharpness of the watch, the uniqueness of the perpetual mechanism and, the nice option of using either a SS bracelet or a well executed rubber band. Mine is a daily watch and I love it.
The Lange you mentioned is very nice as well. Ah, the decisions... the decisions!
My best wishes
