I thought it would be interesting to track the origin and evolution of iconic design; design elements in watches that are so influential that their longevity seems effortless and their reimagining original.
For example, here's a Rolex Submariner 6204 from 1954, followed by a contemporary Submariner, followed by a Bremont Supermarine. While the Supermarine's dial, like dozens (or maybe hundreds) of other watch dials, takes its cue from the Rolex, it isn't unoriginal, or so straightforward that it could be considered a homage piece; though it does in some sense pay homage to the Submariner. In this example, I'm referring solely to dials.
What are some other examples of iconic design (case shape, hands, registers, dials, etc.) that have become part of collective or inherited watch DNA? Breguet hands, anyone?
