Stealth meets solar in this all-black T-Touch Expert Solar. The titanium case is finished with black PVD, the strap is black silicone and the dial is black too, so the only things that catch the eye are the luminous hands and the information you call up with a touch of the crystal.

The appeal is twofold. First, the solar movement: cells under the dial top up the energy reserve whenever you are in the light, which removes the battery anxiety that comes with a feature-packed digital watch. Second, the weight: at around 79 grams on its strap, the titanium case is comfortable enough to forget about during a run or a long day of travel. Underneath the touch interface sit a compass with azimuth, an altimeter, a barometer, a 1/100-second stopwatch, countdown timer, alarm, dual time and a perpetual calendar.

The blacked-out finish also makes it the most understated way into the T-Touch world. It works with technical outerwear, but it is just as comfortable under a black sweater.
