Black & Tan

(1) Hamilton Khaki Seaview Founded in Lancaster, Pennsylvania, 116 years ago, Hamilton has learned a thing or two about making watches. This rugged and water-resistant automatic has all the functions you use daily—namely a date box and two time zones—and none that you don’t. $1,995; hamiltonwatch.com

(2) Bell & Ross BR02 This one is all about the deep. With its huge, ultra-luminous numerals, beefy rubber strap, and a decompression valve for serious scuba diving, the mechanical automatic BR02 is certified to a very rare depth rating of 1,000 meters. $9,900; bellross.com

(3) Festina Shockwave Don’t be fooled by its sleek carbon-fiber face. This chronograph’s classic “engine” is the Valjoux 7750, a superaccurate automatic movement that was introduced in 1974 but remains the gold standard of Swiss engineering. Put it this way: It’s the timepiece equivalent of a Porsche 911 Carrera. $5,995; festinausa.com

(4) Alpina Manufacture Regulator Providing you keep it on your wrist, this surgical-grade stainless-steel automatic never needs winding. But you’ll want to take it off anyway: The see-through crystal back lets you inspect the watch’s inner workings. $3,750; alpina-watches.com

(5) TAG Heuer Aquaracer Chronotimer With both analog time display and a backlit digital readout, the Aquaracer is equally at home in the boardroom and, of course, on the boat: It’s water-resistant to 300 meters, and the stopwatch is accurate to 1/100 second. $2,800; tagheuer.com

(6) Oris TT3 Chronograph Black The TT3’s stealthy carbon-fiber dial is more functional than it looks—there’s a stopwatch, tachymeter, and date window, and the surprisingly luminous hands are easy to read in low-light conditions. $3,750; oris.ch

(7) TX World Time Take a closer look at the dial and you’ll see it: Thanks to four independent, German-quartz-controlled motors and six hands at work, this stainless-steel timepiece displays the hour and season in 24 cities around the world. $450; txwatches.com
