Mechanical watchmaking is full of compromise. There’s only so much that can be done with wheels and springs in a space smaller than a matchbox, and that leads to some little quirks and eccentricities that are all part and parcel of owning one of these little ticking devices. But has Ulysse Nardin managed to conquer the trickiest quirk of all?

The words ‘dive watch’ and ‘Rolex Submariner’ practically mean the same thing these days. It’s the default choice, and for good reason, a major player in the establishment of the category and just a really great watch to boot. Successive facelifts and improvements have rightly kept it at the top of the food chain for decades. But just because it’s a good choice, doesn’t mean it’s the only choice; here are three more dive watches you should check out before you buy a Submariner.

Most people looking for a luxury watch want either a Rolex, Omega or TAG Heuer. That’s quite simply the fact of it, for Rolex especially. And it’s easy to see why—they produce great watches, have rich and interesting histories and carry significant brand cachet. The pool of people who want something a bit different is comparatively small, very small—but it is there. So, for those people, here are three watches that you just might not have considered.

Every now and then a watch does something that is actually quite surprising. Whether it’s a feature or a function, a price point or a something plain outrageous, it stops you in your tracks and makes you take a second look. The Ulysse Nardin Sonata Cathedral Dual Time is one of those watches, but there isn’t just one thing to be impressed by—there’s five.
