• Design & Materials: The watch is housed in a large 47mm brushed titanium case (some variants feature an 18kt rose gold bezel). It is paired with a durable black rubber strap and features an exhibition, see-through sapphire caseback.
• World Time Complication: The dial clearly indicates a second time zone along with a day/night display. The watch face or smoked sapphire crystal is engraved with a rotating or printed ring of 24 international cities corresponding to the world's major time zones.
• Movement: Powered by the Corum Caliber CO 637 (or CO376), this automatic, self-winding mechanical movement drives the hours, minutes, seconds, date, and world time functions. It beats at 28,800 vph and provides roughly a 48-hour power reserve. 
• Functionality: Local time adjustment is exceptionally practical; travelers can press an integrated pusher on the crown to jump the hour hand forward or backward without affecting the world-time city ring. 
• Water Resistance: Built for rugged durability, it offers 100 meters (330 feet) of water resistance
