Great watch. People always talk about how many Submariner and DateJust clones are out there, but I submit that an entire generation of watches paid homage to this design, including ones like IWC's caliber 88 powered dress watches. Even now, there are homages to that watch from Frederique Constant.
Ho my what a piece ! I crossed the way of the 2526 3 times (and funnily 3 time in pink gold which is much less common than yellow), and every time it was a shock, this watch is so classical and so perfect. What a wonder you got here ! I wish I will have one one day , a truly wonderful Patek.
