Certainly I prefer your 5131P due to obvious reason, it is more classy. If I would put on a thick nautilus, my choice will be 5990, due to the additional travel time function. Cheers, Henry
Dear Gordon, Thanks for the fantastic post on the Patek zodiac series. My favourite is the tiger one due to obvious reason.... Among the enamel ones, I like to rooster most, as the composition is more balanced, filling up the whole dial.
