There have been a few great designs in the watch world. The 1930s Reverso, Panerai, Rolex Oyster, 1970s Genta cases, and some would argue the IWC Portuguese watches have unique designs.
The TWINFLY is the best design out of the Swiss Watch world for a long time and is on par with those great designs!
And the Greytech is my favorite too! It's big, but wear it like you would a Panerai and you'll realize it's fairly small.
