If you make me a steel Dato 1st gen with bracelet looking like the one on your top picture I would try my best to acquire one. Unfortunately on a platinum bracelet it would not be worn much by me as it would be too heavy... no matter how cool it looks. It would mostly be spending time in a safe.... which is not something I aspire to when I buy watches. They are meant to be worn....
The 5960 in steel is a superbly comfortable piece to wear and very cool on this black dial....
So my vote.... Dato I suppose.... unfair comparison however....
