most buyers at this level probably own two or more timepieces for different occasions. They are more likely to be global in nature, so what they wear in a city maybe different to what they wear on holiday or in a warmer climate. I can't wear rose gold everywhere for example, the type of metal, complication, lug size and case thickness are all factors. I find Lange much heftier than Patek even with the same case diameter, in short it's a subjective decision based on the individual.
