is about a zillion times better, nicer, more important than any Nautilus.
The 5712 and 5980 may be hot today because the demand is big but don't forget that one day there will be 'enough' of them.
Want an example ? Look at the prices for the Rolex green submariner or new GMT ceramic bezel when they came on the market. Now look at their price .. today
5112 and 5980 will probably always keep good value but please, don't be stupid and dont buy them with this insane premium.
I would accept 10% premium but 30 or 50 % is completely nuts
