Hi,
Thank you for your opinion.
In fact I consider the Nautilus as a piece of steel jewellery, perhaps even more than many Calatrava models.
The 5124G could be an option, but the 5711 would be more worn I think.
Furthermore regarding everyday usefullness you must know that I live on the seaside. I can potentially leave at sea anytime!
I just feel that the 5711 should be my first, incase I have only one, as it would be the most worn.
Cheers
Dje
