Looking to purchase a Cartier Tank Must large with solid black dial. I have looked but it seems DRF is the only option for this model, AF and K11 from what I understand do not have this model in their lineup. I have also looked but can’t find any reviews or comparisons between the DRF vs AF & K11. Makes me a little hesitant to move forward with a purchase with limited information on this watch and the DRF factory. Has anyone purchased this watch or have any experience with DRF in general. Any help would be greatly appreciated.
