The Senseg tactile display uses electrostatics to create the sensation of texture on a touchscreen.
Actually, I screwed up with the model number. The one I have is the T6, which Torgoen no longer lists, but which appears still to be available from dealers.
The Torgoen T01 sports a slide rule bezel. These aviator-style watches are like a poor man's Breitling, with battery-powered Swiss movements assembled into their housings in China. I've had mine for over six years, and I love it. The hands and numerals are large with phosphorescence that remains strong throughout the night. There's also a separate hand that reads in 24-hour time and which can be set to another time zone -- handy if you conduct overseas business.
