Solar power changed the T-Touch from a watch you occasionally re-battery into one you can simply wear. The T-Touch Expert Solar draws energy through its dial, and this version pairs the 45mm titanium case with a leather and textile strap for a softer, more versatile look than the usual rubber.

That strap is the story here. It takes a technical, instrument-packed watch and makes it work with a jacket and jeans, while the titanium case keeps the weight low. The tactile sapphire crystal still gives you the full toolkit: compass with azimuth, altimeter, barometer with pressure graph, chronograph, countdown timer, regatta-style yacht timer, alarm and a second time zone, all illuminated by an electroluminescent backlight when the light drops.

The black dial integrates the solar cells and the LCD neatly, so the face stays clean, and Super-LumiNova on the hands and indexes keeps it legible in the dark. It is a smart fit for travelers who want one watch for planes, cities and trails without packing a charger.
