The 5110p has been my holiday and travel watch for years. Because I don't go swimming a lot and because you can go anywhere with this watch, it is always about discretion and elegance. And I am now happy to add my 5066 to every trip. Nice combo IMO.
...and Aquanaut as well a good option in summer but as for me I have a preference for the more recent design 5167 (or even better 5164 travel time but not the same league...).
