The movement is still not as robust as a Submariner watch though. And the lack of date - while more aesthetically pleasing, is a small danger. If I were stranded on a deserted island (who knows, this may be a paradise) I would still want a Submariner as my watch - preferably with date since I'd need to keep track of the date. Plus, both watches have true water resistance which is helpful for fishing, island activities, etc.
After that, the larger rotor of the Nautilus 5711 and the date is practical - large rotors wind more reliably. Although the Nautilus movement is not as reliable as the Rolex movement. The Nautilus also has a short power reserve - there will be inevitable times that you will be sick - and if you need to tell the time, a 48 hour power reserve might be too short. The Nautilus 5711/1A has 120M water resistance! The 5712 only has 60m water resistance - which means you cannot go swimming in it! BUT! The water resistance on the Nautilus is a little more finicky due to the use of an exposed rubber seal under compression (between the bezel and the case) and while the crown is screw down, there are no other fancy gasket systems inside the the crown system (Rolex has a special double/triple gasket system where at least one of the gaskets is always under special pressure even when the crown is open).
Due to the Nautilus' rubber components being exposed, it is more likely to experience degradation and thus, there are greater risks.
The Chopard Alpine Eagle XPS however has a few other advantages. It has 100m water resistance and no exposed rubber seal. The crown doesn't have any fancy seal mechanism like the Rolex however (JLC also used this system in some of their Master Compressor watches where they compress an O-Ring to maximize water resistance - a somewhat similar concept as the Rolex). The Alpine Eagle XPS' movement is the 96 series which if memory serves me winds bi-directionally, this is notable and significant since most micro rotors tend to wind only in one direction (for example, Patek's 240 caliber, a micro rotor used in the 5712, only winds in the counter-clockwise direction). The Alpine Eagle also only needs 800 rotations a day to wind the watch fully, and it has a fairly long power reserve of approximately 65 hours. This might be a great watch to wear as a casual watch at the tennis club, a watch to dress up for nice evening dinners and shows in the city, a watch to wear while on holiday on a beach and swimming, and a watch to be worn at the office. The James Bond watch! Plus you can get stuck on an island with it! I'd take it over a Nautilus 5712 for sure if I was going to get stuck on an island - although I'd wish it had a date.
