Tissot is switching to solar time. A hybrid between the traditional watch and smartwatch, the new T-Touch Expert Solar’s dial is covered in solar cells which charge up the battery. Tissot launched its first tactile watches with the Locle model in 1999. Things haven’t certainly changed with the T-Touch since it first launched with six functions (including the compass, altimeter and barometer). The Navigator featured no fewer than 150 time zones in 2004 and the 2009 Sea-Touch has a depth sensor and tells wearers the speed of the dive. The Expert Solar is in the same vein: the nonmagnetic titanium case houses a perpetual calendar with the date and week, two alarms, a dual time zone, weather forecast with relative pressure, an altimeter with a difference in altitude sensor, chronograph, compass, countdown timer, azimuth, sailing function and illuminator.
