Wenger Swiss Commando Chronograph Watch. Wenger Mens Commando SR Chronograph Watch This absolutely amazing mens Swiss chronograph by the maker of the Swiss Army knife is loaded with modern-looking dials, rings and numbers, and is a mechanical marvel. It was featured in Skymalls holiday catalog. The three sub-dials measure time in 60 second, 30 minute and 12 hour intervals. The Commando SR performs multiplication and division, and a tachymeter measures speed over a known distance. A unique locking circular slide rule converts statute miles to nautical miles, MPH to KM/H, converts currency, and converts weight or length from standard to metric. The chronograph is powered by 13-jewel Swiss quartz movement accurate to 1/10 of a second per day. There is a date display, scratch-resistant mineral crystal, luminous hands and numerals, water-resistance to 100m (330 ft.), a stainless steel case with screw-on back to ensure water-resistance, and a solid 3-link stainless steel bracelet with divers buckle and safety clasp.
