The modern Rolex Submariner (US$7,500) has almost become a cliche, since it can be spotted on countless wrists in nearly any bank or office all over the world. However, it’s achieved this status for good reason: it’s simply one of the best all-purpose watches you can buy. The black ceramic bezel, clean utilitarian dial, and bulletproof construction make it a near perfect choice for most people. If you’re more a pilot watch kind of guy, IWC’s latest, the Mark XVIII (US$3,950) is the archetype on which all others are based. The dial is as legible as they come and at 40mm it can even work as a dress watch on a slim leather strap. With all the work Panerai has done to keep innovating on both the design and technical fronts, it would be crazy not to mention the Luminor 1950 (US$9,100), which sports both Panerai’s signature multi-layer dial and a manually-wound in-house movement.
