A watch is desire able and appealing to me when, in addition to many other things such as design, technology, history and philosophy behind it, it has two main features: wearing comfort and functionality.
The Aquanaut is super comfortable to wear, very accurate (at least mine) and has a practical water resistance of 120 m.
I'm very (!) ... picky about the dial design of watches, therefore I don't like the dials of most Nautilus and Aquanaut models because of the white date windows which often seem ti be placed a bit … loveless and uninspired to me (sorry to all the fans!)
For me, the Traveler models here are a pleasant exception because the dial design is the most harmonious for me.

P.S.: The Aquanaut Traveler is currently the only Patek I own.
