I actually love the case size and shape of the world time, but at least for me the 1958 tribute, though smaller than I normally like, is without question a modern day legend. With that being said I would never buy another watch less than 40mm. And given the offerings in the line up since the geophysic, it is unlikely I will buy another one. No doubt it is a good thing that only a few watches truly inspire (in me) the brining desire to own.
