The 5712, for the beauty of its dial...
It may be different if you spoke of a Nautilus Vintage, a Jumbo, for example, with a Tritium dial, as the indexes are thinner than in the new version ( 5711 ), and the problem of the 5711, ( well, for me ), is these big luminova indexes...
Approach you dial to a light, and look at your dial...
It's less evident with the 5712...Which is my favourite in SS.
Best.
